Basic (I think) question about OpenFiler in ESXi environment

• Question about my off ESXi environment

  Hi all

  I have a question that should be easy to answer. We can to the bottom of our building for maintenance on a backup generator. This means that all servers must be stopped including our VMware environment. This is the first time I had to do this since we put in our VMware environment. My question is:

  After that I have put all my virtual machines do I place my ESXi hosts in Maintenance mode before turning off their or can I just turn off the host without this concern. We have active and any HA so I thought that if I them off without Maintenance mode then HA can see that in some type of error and start trying to migrate everything.

  Everything suggests that someone could provide would be greatly appreciated.

  I would say not only put your hosts in maintenance mode, but also disabling HA.  This will help eleviate all false positives.  When the power is restored, gourmands on the one host at a time, out of maintenance mode and then turn on the guests.

  I think that it will be fine to keep the active DRS, which will help balance the load as each host out of maintenance mode.

• Question Basic setting, ask questions about the buffer cache

  Database: Oracle 10g
  Host: Sun Solaris, 16 CPU server
  
  
  
  I look at the behavior of some simple queries that I start the tuning of our data warehouse.
  
  Using SQL * more and AUTOTRACE, I ran this query two times in a row
  
  SELECT *.
  OF PROCEDURE_FACT
  WHERE PROC_FACT_ID BETWEEN 100000 AND 200000
  
  He finds the index on PROC_FACT_ID and conducted an analysis of the range of indexes to access the data in the table by rowid. The first time, that it ran, there are about 600 physical block reads as data in the table were not in the buffer cache. The second time, he had 0 physical block reads, because they were all in the cache. All this was expected behavior.
  
  So I ran this query twice now,
  
  SELECT DATA_SOURCE_CD, COUNT (*)
  OF PROCEDURE_FACT
  DATA_SOURCE_CD GROUP
  
  As expected, he made a full table scan, because there is no index on DATA_SOURCE_CD and then chopped the results to find the different DATA_SOURCE_CD values. The first run had these results
  
  compatible gets 190496
  physical reads 169696
  
  The second run had these results
  
  compatible gets 190496
  physical reads 170248
  
  
  NOT what I expected. I would have thought that the second run would find many of the blocks already in the cache of the pads of the first execution, so that the number of physical reads would drop significantly.
  
  Any help to understand this would be greatly appreciated.
  
  And is there something that can be done to keep the table PROCEDURE_FACT (the central table of our star schema) "pinned" in the buffer cache?
  
  Thanks in advance.

  Your comment about the buffer cache used for smaller objects that benefit is something that I asked about a good deal. It sounds as if tuning the buffer cache will have little impact on queries that scan of entire tables.

  Chris,

  If you can afford it and you think it is a reasonable approach with regard to the remaining segments that are supposed to benefit the buffer cache, you can always consider your segment of table with 'CACHE' that will change the behavior on the full of a broad sector table scan (Oracle treats small and large segments differently during the execution of table scans complete regarding the cache of) marking stamps, you can override this treatment by using the CACHE. NOCACHE keyword) or move your table of facts to a DUNGEON hen establishing a (ALTER SYSTEM SET DB_KEEP_CACHE_SIZE = ), modify the segments (ALTER TABLE... STORAGE (USER_TABLES KEEP)) accordingly and perform a full table scan to load blocks in the cache of the DUNGEON.

  Note that the disadvantage of the approach of the KEEP pool is that you have less memory available for the default buffer cache (unless you add more memory on your system). When an object to mark as being cached is always is in competition with other objects in the cache buffers by default, so it could still be aged out (the same applies to the pool of DUNGEON, if the segment is too large or too many segments are allocated age blocks out as well).

  So my question: How can I get for a parallel analysis on queries that use a table scan complete such as what I posted in my previous email? It is a question of the provision of the "parallel" indicator, or is it an init.ora parameter I should try?

  You can use a PARALLEL hint in your statement:

  SELECT /*+ PARALLEL(PROCEDURE_FACT) */ DATA_SOURCE_CD, COUNT(*)
  FROM PROCEDURE_FACT
  GROUP BY DATA_SOURCE_CD;
  

  or you could mark an object as PARALLEL in the dictionary:

  ALTER MATERIALIZED VIEW PROCEDURE_FACT PARALLEL;
  

  Note that since you have 16 processors (or 16 cores that resemble Oracle 32? Check the CPU_COUNT setting) the default parallel degree would be usually 2 times 16 = 32, which means that Oracle generates at least 32 parallel slaves for a parallel operation (it could be another set of 32 slaves if the operation for example include a GROUP BY operation) If you do not use the PARALLEL_ADAPTIVE_MULTI_USER parameter (which allows to reduce the parallelism if several parallel operations running concurrently).

  I recommend to choose a lesser degree parallel to your default value of 32 because usually you gain much by such a degree, then you can get the same performance when you use lower a setting like this:

  SELECT /*+ PARALLEL(PROCEDURE_FACT, 4) */ DATA_SOURCE_CD, COUNT(*)
  FROM PROCEDURE_FACT
  GROUP BY DATA_SOURCE_CD;
  

  The same could be applied to the paralleling of the object:

  ALTER MATERIALIZED VIEW PROCEDURE_FACT PARALLEL 4;
  

  Note When defining the object of many operations in PARALLEL will be parallelisee (DML even can be run in parallel, if you enable dml parallel, which has some special restrictions), so I recommend to use it with caution and begin with an explicit indication in those statements where you know that it will be useful to do.

  Also check that your PARALLEL_MAX_SERVERS is high enough when you use parallel operations, which should be the case in your version of Oracle.

• Basic questions about the storage on ESXi

  Hello

  We are about to implement a VMware ESXi environment and I would like to get some clarification on the storage in ESXi before proceeding.

  Material: 3 guests and HP EVA4000 FC 4 TB SAN.

  We execute the file, mail, web, directory, application and database servers.

  Some of these services require quick I/O and some require data to be 'seen' by at least 2 virtual servers for HA.

  Can I use discs RDM for HA/Clustering servers and for those who need quick I/O, or can I use VMDK:s?

  If I present to you the entire 4 TB SAN ESXi can I then several virtual servers use certain parts of this 4 TB SAN as discs RDM and other servers use certain parts of this SAN as VMDK:s? (Do we have virtual HBA:s in ESXi?)

  Thank you

  Yes. But you must consider as usual VMDK of hard drives in this case, you must install the cluster file system there.

• (Basic) question about layers

  Hi all!

  I'm a little Photoshop-beginner and I have a question about layers, just as the title suggests. I have a bunch of PNG files which are the design of what happens in the UI (user interface) for an app Anyhow, I need to break down each graphic element in the files (for example, the logos, the "buttons", the small images) in different layers. How this is done more efficiently?

  Any help would be much appreciated and I hope that I have explained the task well, but if you need additional information about the files or the task, I will be happy to provide that.

  Thanks in advance,
  EM

  Use the Quick Selection tool to select each item and then press Ctrl + J (Cmd + J) that will create a separate layer. You can select with the rectangle selection rectangle if you want straight borders. Each item will have a transparent background which will allow you composite with other pictures or blank documents. Click on the symbol of the eyeball in the layers palette to the right to turn on and off and then you can view layers individually.

• A few questions about the Satellite A100 PSAANE

  Hi friends,

  I have a Toshiba Satellite A 100 - PSAANE with Vista Home Basic preinstalled in it.
  Now, I have a few questions... I mention below: -.

  (1) if I want to format my laptop, I need a CD to install for Vista Home basic... then I don't have this Toshiba CD when I bought the laptop. So how do? question: How can I format it?

  (2) can I change my Vista Home Basic to windows XP? I think it's much faster than this one. is it advisable?

  (3) I have a GB of RAM in the laptop. Increase the RAM? I think that my laptop has become to slow down. is it advisable?

  (4) and on my screen, everytime I try to change my profile screen to windows Classic view, my screen begins to blink. and after a while, the screen turns off. So I can't change that. I put the color scheme of windows vista only. What to do about that?

  Please help me friends. Thanks in advance.

  Hello

  Here, a few questions about the number:

  (1) usually, you should get the Vista Toshiba Recovery DVD. If you didn t receive this DVD then you can order it here https://backupmedia.toshiba.eu/landing.aspx or you could install the disc of Microsoft Vista.

  (2) of course, you can do this. I think that Win XP drivers can be downloaded from the Toshiba driver page.

  (3) Yes, you can upgrade the RAM. For more information, see your manual or search on this forum for similar topics

  (4) maybe it s associated with the graphics driver. Check if you can update. I would recommend additional check if you are using the latest version of the BIOS

• Technical questions about X 1 carbon Touch base

  Please forgive me, I'm still recovering after the shock and frustration generated by dealing with Lenovo Tech Support.

  I recently received my X 1 carbon Touch and I have tried to understand some - I think - fundamental questions.

  As you know, to win 8, Lenovo doesn't have a custom recovery solution / owner. However, there are a score of Lenovo recovery on the machine. I'm /assuming/ this, somehow, can be used through the default / built-in mechanisms of recovery Windows, but I want to know exactly how without necessarily experiencing myself with it.

  In addition, the computer seems to be equipped with a mechanism of alternative stand-by, fast recovery called Intel or something like that. It is enabled in the BIOS and apparently makes use of a hidden partition of ~ 8 GB on the SSD. However, I find no indication of this mechanism working. There are no settings that I could find in Windows. I changed the BIOS to 'Immediately' setting in order to test the functionality, but put the computer to sleep does not seem to generate behavior that is somehow different from regular sleep.

  In any case, I would like advice or information on my questions above. I understand works the thing of recovery fast in order to decide if I want to recover the partition or not. I would also like to know my options I should never need re - install the delivered factory OS without actually crossed the steps. I would also if someone could tell me the best way to get support from Lenovo.

  / * I called Lenovo technical support with these issues. The person sponsor and those to whom I then was sent to had no idea what I was talking about. They had difficulty understanding terms like partition, standby, sleep, resume, and even software/hardware and implementation. It was suggested that my computer may be Intel and Lenovo not... They seemed to really come from an age of the computer. I asked to speak with someone who would have some basics of the machine that Lenovo delivered to me. I find it reasonable. At that time, I was told to talk to a knowledgeable person, I have to pay a fee. Seriously?

  elfstone,

  To find out how to work the various Windows recovery methods, please see this Microsoft Web site:

  http://Windows.Microsoft.com/en-us/Windows-8/restore-refresh-reset-PC

  The sole purpose of the recovery partition is to work with the "All delete and reinstall Windows" function of Windows 8.  If you have specific questions about the factory recovery that you can't get items from Microsoft, let me know.

  Regarding the plan of hibernation from Intel, as you noted, it takes a partition dedicated to your SSD which cannot be used for other purposes.  The only parameter in Windows is inside the application of arrangements of Lenovo in the power section.  Lenovo calls this function "in waiting for 30 days.  The only thing you can do is it turn on or off.  Here's how works "waiting for 30 days:

  1. When you close the lid, or otherwise put the system into standby mode, the system of standby for 3 hours.

  03:02 hours, the system will wake up and check things like not attached AC, wake-on-LAN not activated, USB device not attached, etc..  If conditions permit, the system will enter wakefulness of 30 days for example deep sleep.  If the system returns in normal mode to 'sleep'.

  3. deep sleep means that the content of the memory is written on the special hibernation on the SSD partition.  It is very similar to the traditional hibernation except what happens faster using methods of BIOS instead of Windows methods.  But this isn't anywhere near as fast as normal sleep/recovery.

  4. the system out of deep sleep when the cover is opened or when you press the power button.

  You have found the BIOS settings, but in fact they are ignored when Lenovo settings (and package of dependence of the Lenovo parameters) are installed on the system.  I don't really know why this design choice has been made.

  Personally, I don't see value in 30 days standby, not enough value to want to give up my expensive SSD 8 GB.  I exclusively use sleep/recovery.  The battery will last several days.  And if I'm going to be away from the computer for a long time, then I'll just stop it.

• General question about the updates and version number

  I have a general question about versions and update.  I'm new on this and am in the deep end of learning I want.

  In vSphere web client, I see the following versions (these are exactly as the seller, he left a few months that I have screenshots in my documentation that match)

  Version - VMware ESXi, 5.1.0 1612806

  Profile - Dell (updated) ESXi - 5.1 - 799733 (A00)

  I am trying to familiarize themselves with the Update Manager and I noticed that there are a lot of patches and updates available.

  Lists of Update Manager 5 patches as "Missing" with Red x but directly above them are a list of patches with green tick indicating that "installed" - it is perhaps obvious, but im guessing 'installed' means really installed when displayed on the screen - there is an update installed, labeled "ESXI 5.1 all the update 2-' would be able to tell that it has been installed by the details of profile/version above?

  I don't think it's a big deal at this stage, but if I install all missing patches and then the details of the version/profile change in summary screen?

  I hope this makes sense.

  Thank you

• A question about the virtual processors in the prompt

  Dear Sir

  I have a general question about the number of virtual processors in the guest system.

  I use VMware ESXi 4.0.

  Say if my physical host has only 2 cups carrots (with or without HT should be the same), then is - it true that I can only attribute 2 virtual processors per virtual machine?

  Is it possible to give 4, 8 virtual processors in virtual machines?

  In my drop down menu I can NOT choose more than 2 virtual processors per virtual machine, I want to just make sure that it is not the problem of license.

  Thank you very much.

  Hi Nanfang,

  linanfang wrote:

  So the general rule is the number of vcpus don't CAN NEVER exceed the number of physical processors. Is this correct?

  Replace "physical cpu" by "physical cores" and you are right, because a vCPU is mapped to a kernel. For example, you can assign 4 vCPU with a Quad-Core processor.

  If you think about it, it makes perfect sense. If you would be able to map 2 vCPU to the base, the vCPUs had to wait for them all the time because the physical kernel can simply perform an action at a time, why you would decrease the performance of your virtual machine by setting 2 vCPUs.

  It is not changed in vSphere 5.

• Questions about the installation of ColdFusion 9.0.2 version of existing in version 9.0.1

  Hello

  I'm currently running ColdFusion 9.0.1 enterprise edition and plan to upgrade to version 9.0.2 version. I understand that this requires uninstalling existing 9.0.1 and perform a new installation of version 9.0.2 version. My concerns are below:

  1. for the installation of the 9.0.2 version the 9.0.2 installer (demo / trial version) must be downloaded and the existing serial number (used in version 9.0.1) can be given during installation to convert it in fully registered mode - please correct me if my interpretation is incorrect here. My question is will the existing serial key (as shown in the page Admin of CF 9.0.1 version version) work with the 9.0.2 version as well?

  2. There are many features that are present in the current 9.0.1 version - for example the sources of data configured in the Admin see Y page there a way I can save these configurations of the existing version and to migrate settings to the new 9.0.2 install, or what I have to do the entire configuration manually after the installation of new? Data sources is something I can think; What other configurations can I save, if such a provision is available?

  3. in the installation of the 9.0.2 version there is a question about "configure the Web server for CF Connector" allows me to add Web/sites Internet servers during installation. If I select "built-in Web server" as the option (so do not configure any Web-site Web server), can I change this and configure Server/site later, after compeleting installation?

  What would be the things I need to be careful during this installation to version 9.0.2 from 9.0.1?

  Thank you!

  Arun-

  I did a successful version 9.0.2; installation answering my own questions, for the benefit of future development-

  1. Yes. Only the serial number is required (as shown in the Page of the CF Admin of existing facility)

  2 configurations (for example: data sources) can be exported. Go to CF Admin Page, click on packaging & deployment, click on Archives of CF. Basically, you export settings as files with the extension archive. car. Once exported from the current installation, it can be imported by clicking on the button deploying car file.

  3 server configuration can be modified (Add/Remove) by using the "Web Server Configuration Tool" which is installed by default with CF 9. You can find it under program files (windows OS).

  I had some problems during the installation. After installation, the CF Admin page would not be made. Virtually no cfm page don't take charge, because the extension is not known by the IIS (or the server you are using). To set this up, use the "Web Server Config Tool" mentioned above. This launch and activate the check box that is on the rendering cfm pages (forgot the exact name). Once this is done, cfm pages must load. I had to enable this and then do a reinstall but.

• Question about the interruptions and priming

  Hello

  I had a few questions about the startup and interruptions in a virtualized environment

  Assuming that, plenty of virtualization (no material assistance to virtualization of memory ).

  1 initialization: in an ordinary PC, the boot process starts with the BIOS, to expansion ROM, back to the BIOS and MBR secondary boot record, then grub (is it) and finally the operating system. In a virtualized environment with VMM running directly on top of hardware (Native VMM), how is the initialization of the different process, as I understand it takes BIOS-> Expansion ROM - > BIOS-MBR-> other record secondary-> VMM-> OS--> applications >. Am I right on that?

  2 breaks: VMM examines the source interruptions prior to the interruption, so in a multicore environment, assuming a 2 processor core, how the VMM decides on the kernel for which the interruption in intended, prior to shipment of the interruption. Interruptions are tag ID, said core ID?

  Thanks in advance

  It is simplistic but essentially correct.  A metaphor would be a little better thinking that the hypervisor/vmm is an operating system, except that the process on this operating system are requests or comments OSes.  If the BIOS-> OPROM-> BIOS-> MBR-> hypervisor-> init process of the hypervisor-> reviews of fork () s operating systems.  This can become blurred by the design choices (for example Xen/Hyper-V init start a coded parent hard partition that makes hypercalls privileged to fork() guest OSes; ESXi init runs a very limited subset of applications directly on the hypervisor and ESX Classic is somewhere between these approaches).

  There is a subtle distinction between "hypervisor" and "www."  The "hypervisor" is the operating system of single root (e.g. ESX) who interacts directly with the hardware and has access to everything; a hypervisor is not to be used to run virtual machines.  When we talk about a "hypervisor", the tendency is to describe something which is a BONE (although usually a minimal OS designed only to run virtual machines).  The "www" is the layer that allows a virtual machine run: it provides the interposition, virtualization and emulation services and can be plural (for example a vmm by guest operating system).  Architecture of VMware deal with these two separate components, while most other virtualization platforms merge the two.

  Strictly speaking, the interruption is not transmitted to a guest operating system - receives the hypervisor (or rather the VMM it transmits to the hypervisor), the hypervisor drivers interpret the interruption (for example reading package of NIC, I/O process of HBA, the timer tick completion), then after a new appropriate break in the guest OS.

• A question about type

  Okay, at the risk of exposing me like a complete jerk, I need to ask a question about type.

  I use Fireworks CS4 to design a website of 40 to 50 pages. Most of the site is composed of ten stories, each taking two to five pages of the site. I use ghraphic and pictures to break up the grey type and illustrate the words. I anticipate using 14pt Arial for my policy. The text will be displayed on a 'unique' (that is to say, not repetitive) texture.

  I put on my pages with photos and other graphics, and I glued the type of original stories around the images. (I don't use Lorem ipsum for text space booked because I wanted an accurate measure of the screw-the-page notice words.) In other words, I wanted to be sure that everything fit and don't let no troublesome space at the end).

  I know that I do not export the type with images in Dreamweaver. I'll remove the text in Fireworks when I export, then paste it in Dreamweaver so that the pages appear as I have originally designed the.

  However, my question is this: If a reader opens one of my pages with his default computer to, say, 12pt Verdana, if it screws up the layout of my page? As I said above, I have designed the pages at Arial 14 pt. If the type will flip off my pages - or type will inches less on a page - if the Player browser is set to a different font size or point? If Yes, what can I do to make my pages (or contraction) to adjust the reader his reading preferences?

  Thanks again for your help. Of course happy that I do not use my real name on it.

  When you write the HTML code, you place the images next to the paragraphs they are associated if the police or the window changes size, then the whole of the document is redéroule, but logically, everything to its planned place. This can be frustrating for people who are used to define exactly where the images appear with respect to the text and even kerning and spacing to make a line "so." You will have awkward gaps somewhere, let it go... let the way you free from this concern.

  Everything is in a box, however. In this box, you can put images repetitive or expandable. So yes, you can put a background behind the text, no repetitive image on each of your pages and you should be able to set the box so that duplication of the background image will not appear if it is larger than the active area. (I think it would be in the CSS overflow divs property... you'd have to check).

  Here are some tutorials using broad, non-repetitive background images for the page. You could adapt the technique to a content div:

  http://Line25.com/tutorials/basic-Web-page-background-techniques-with-CSS (scroll down)

  http://www.WebDesignerWall.com/tutorials/how-to-CSS-large-background/

  On the other hand, however, lines of text that are more than 2 to 2.5 wide alphabets are difficult to analyze. If your site is intended to be text-heavy, you might be better off with a fixed width for your text box.

  I think that the comment the blogger relates using Fireworks Slicing page to export HTML code, which gives you a fixed design, based on a table. The HTML code, you can export FW is not for live sites. It's just for prototyping. It is better to use CSS for layout, rather than tables, because the code is easier to maintain. I came across this interesting tutorial (the author uses Photoshop, but any graphic program works if you want to follow along):

• A few questions about the difference between the Satellite P70, L70, S70

  Hello, I have a lot of questions about the P70, L70, S70 series that come with a 1920 x 1080 panel.

  (1) what are the differences between the L70 and S70 series? With the exception of the RAM and HARD drive capacity, books seem pretty identical.

  (2) P70, L70, S70 doesn't support a 2nd HARD drive or it's just the P70 series that support?

  (3) all the three (P70, L70, S70 series) come with the same TFT panels?

  (4) of the above series, which supports mSata?

  (5) all the model of each series are delivered with support from mSata? For example, it could be that L70 - a - 13 m supports mSata is not the case of the L70-a-146?

  (6) all the foregoing, are delivered with a S - ATA II or III S - ATA interface?

  (7) who is the best of these series listed? I'm trying to understand what makes the big difference of S70 to P70 except for the envelope for example.

  Thank you in advance.

  > (1) what are the differences between the series L70 and S70? With the exception of the RAM and HARD drive capacity, books seem pretty identical.

  What models Sat L70 and S70 do you mean exactly? There are different L70-xxx-xxx and S70 models on the market that supports different hardware specifications.

  (> S70 2) P70, L70, support a 2nd drive HARD or is - it just the series P70 that support?
  As you can see in this [Sam P70 HDD replacement document, | http://aps2.toshiba-tro.de/kb0/CRU3903II0000R01.htm] the P70 series supports the 2nd drive Bay HARD, BUT even if there is a 2nd HARD drive Bay, this does not mean that you can use the 2nd HARD drive. In the case where the 2nd HARD drive Bay are equipped with HARD drive connector, you can use the 2nd HARD drive

  I also found the [Sam L70/S70 HDD replacement | http://aps2.toshiba-tro.de/kb0/CRU3703HG0000R01.htm] the document on the Toshiba page and there I see this 2nd HARD drive Bay is not available

  (> 3) all three (P70, L70, S70 series) come with the same TFT panels?
  See point 1). Different P70, L70, S70 models were equipped with different material parts.

  (> 4) of the series above, which takes in charge mSata?
  As far as I know that some P70 models are equipped with an mSATA SSD of 256 GB.

  (> 5) do all the model of each series are delivered with support mSata? For example, it could be that L70 - a - 13 m supports mSata is not the case of the L70-a-146?
  See point 4) not all models supports the same hardware specifications

  (> 6) all of the above, come with a S - ATA II or III S - ATA interface?
  I don t think that SATA III is supported. I guess it would be SATA II

  (> 7) which is the best of these series listed? I'm trying to understand what makes the big difference of S70 to P70 except for the envelope for example.
  Not easy to answer because there are too many models released in Europea.
  And not all models are available in each country. So I guess you will have to look for the models that have been released in your country.

• where to post a question about iTunes on the iPhone?

  I have a question about a problem with iTunes on the iPhone (iOS), but I do not see a 'Community' with this title (or anything close;  I have no idea what "iTunes U" means).

  For lack of a better idea, I just posted to the community "iTunes for Mac", but I don't think that's true.

  It should probably be posted in the community Using iPhone Apple Support communities. I'll ask a host spend your question in iTunes for Mac, if it has not already been moved.

• Satellite U405D - several questions about overheating/disassembly/upgrading etc.

  Hello

  I have several questions about my old one by Satellite U405D-S2910

  1. when it works, after 2-3 hours (I run usually small programs such as safari, msn messenger and bsplayer) CPU gets 85 to 90 C (178-188). When I play age of Empires 2 (come on, its an old game) like 2-3 hours, it stops. What could be the possible reason? Furthermore, let me inform you about the climate of the city I live, 30 c temperature - humidity 25-35% (today).
  PS. CPU is AMD Turion 64 X 2 Dual-Core Mobile Processor. Model RM-74

  2. I'm going to disassemble my laptop in order to clean its cooling units (I think at the rate of overheating is this). It does seem like a desktop computer, so complicated. Ive seen a disassembly not to not (btw, its so difficult to spell dismantling :) I think Im going to do this. What are your suggestions on this subject? experiences could help me?

  3. my laptops is Ram 2x2gb PC5300 DDR2 667 MHz SDRAM memory, I want to replace RAM memory 2x2gb MACH XTREME DDR2 1333 MHZ CL9 NOTEBOOK. Should I do it? Fit my portable, stable work? any suggestions?
  PS. motherboard chipset AMD M780V

  4 - Finally :), should I use OS 64 - bit or 32-bit OS (win7)? what OS would you use if you were me?

  Thank you.

  Hey Buddy,

  1 + 2. I think everything is related to a higher internal temperature and you must clean your laptop using a jet of compressed air. That is why it s not necessary to remove, just blow softly and soon the air through the laptop. You can buy such compressed air which squirts of each computer store I think and it takes only 5 minutes.

  3. in my opinion he should forget this update! The speed of the RAM is related to the FSB of the CPU and as much as I know about Satellite U405D it s 667 MHz so it s already the RAM faster than you can have. Save your money and buy a larger HARD drive or in the best case a SSD that can really improve the performance!

  4. in my view, the answer is clear: Windows 7 64-bit.
  Only a 64-bit OS supports full 4 GB of RAM. ;)
