How to increase the RAM memory on a virtual computer.

Hello!!!

My 4.1 infrastructure

vCenter Cluster with 4 ESXi host

I installed a VM with OS Linux Centos 5.5

VM has 2CPU, 2G_RAM, 7_GHD

I want to increase the RAM up to 4 G.

I have increase up to 4 GB with vSphere. But when I run MV, I run commands such as 'free' or 'top' and I discover who recognize only 3 GB

But here:

http://KB.VMware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1014006

This behavior is expected and does affect adversely the operation of the guest. Physical address extension (PAE) will not allow the guest to recognize all 4 GB of memory.

Does anyone know how to increase?

Thank you very much.

JOs.e

As you may know, 32 bit OS' are limited less than 4 GB of RAM, unless the EAP is enabled, and it will impact your server when it starts to use on 3GBs of RAM.

I suggest that using a 64 bit OS, this way you can throw all the RAM you want in it.

Anyway check this: http://www.cyberciti.biz/tips/redhat-enterprise-linux-4gb-plus-ram-support.html

If you finish by activation of EAP, make sure you only take a snapshot of the VM as VM/backup.

  • How to increase the video memory on Portege Z830 - 11 M?

    Hello!

    I have a Toshiba Portege Z830 - 11M. I want to increase the video memory.
    I don't know if it's possible and how to do it. I tried to open the bios by pressing the F2 key (as in the product specifications, I received with my laptop) and I arrived at the Toshiba help settings. The ESC and F1 keys open the Windows startup settings. If anyone can help me, please advice.

    Thank you very much.

    Hi Mishal

    In general the Portégé Z830 - 11 M is designed to escort us in usual daily activities such as sending mail, Office Automation and communication internet and feature thin and lightweight design allows us to take it anywhere.

    Hardware configuration has limited the performance of course, but at the same time offer excellent multitasking and long battery life. As far as I know on this machine you will not find any option to increase the performance of the GPU and everything that it works automatically.

    According to some feedback non demanding games should be playable with this graphics card too.
    I can't imagine that you want to play games with this machine so I would like to know what it is to ask about the graphics performance more.

    Hello
    pls help me! I have this laptop, and I want to increase the video memory from 8 MB to 128 MB, because for the moment its share only 8 MB. How to do this?
    I am grateful for!

    Hello

    the machine cannot tell what size memory it should use. He has the ability to use 128 MB. But he will not use memory that is really necessary. So if you don't play games 3D or something like that, you don't need as much memory video.

    Hello just curious if anyone knows how I can increase the video memory on my new yoga 900. I looked at the bios screen, and I don't see an option to change it. Thanks in advance.

    Good day and welcome to the community.

    The amount of memory used by the integrated video controller depends on the total system memory, and is controlled system (vs user).

    Hope this helps to clarify.

  • How can I increase the RAM (memory) for my computer to hp dc5750?

    I bought one of these pc hp dc5750 form small factor that invade now right-handed ebay.  It came with only 1gig memory 80gig hardrive and processor bicoeur AMD Athlon 64 x 2 2.0GH but I can not know the socket type I think it's an am2?  I'll update my AMD Athlon II X 2 215 2700 MHz proc @ in my hp p6203w, but it is an am3 I think and I was wondering if the motherboard will accept an am3 as my another hp witch will take either.   I had also (lots of memory Samsung - 2GB (2x1GB) PC2 - 5300U - 555 RAM NON - ECC Unbuffered 240-pin) off ebay thinking they were a matched set, but when I got them one had a 1R - 8 x and the other had a part number x 8 - 2R

    I was woundering if I ran these two stick and the two 512 original supplied with the pc that are 1R - x 8 a face cards will be it atcually be able to use all 3 concerts cuase I saw a diagram that shows the configuration of two 1gigs and 2 512 in slot 2 and 3.   but he said someithing on all correspondence.  Once I put them all in the computer it says there 3gigs but I don't know if it of using everything or if Im better off just runing the two 1gig sticks or both will have to be 1R - x 8 or 2R - x 8 (it is the motherboard that has all the right to side by side 4 memory slots and not in separated couples and the other model nuber 8305-65U)

    Oh yeh Im runing win7 64 bit

    Type of socket original title: hp dc5750 and memory?

    + 1 on the suggestion of Nirmal - contact HP support, but--

    All very hit and Miss. Miss Aries matching is not a good idea and miss-corresponding to the quantity (2x512MB - 2 x 1 GB) often fails. You can get lucky and the machine will start, but the RAM performance will suffer without worrying.
    There only seems to be a lot of people who are able to run the 3 GB of RAM (laptops for most), but it's a strange configuration.
    Better to have two sticks of 2 GB and (assuming that Win7 32-bit) only have access to about 3.25 GB of that you still get the benefit of the dual channel performance.
    I have an old (built in ' 05) PC with an AMD 939 socket cpu and experimented with two 512 MB and two sticks of 1 GB (I have 2x512MB sticks all the time), the computer does not start in windows with this configuration.

    AMD made a number of processors with the Athlon 64 x 2 designation. Several are socket 939, others may be AM2. He must know exactly what processor and the motherboard to know what are the components.
    If the RAM is DDR2, there is a chance of the cpu/motherboard are AM2.

    The upgrade to a HP or other OEM PC can be a minefield that they often use a design of the 'special' motherboard (if you use the HP chipset drivers this is probably one of their 'special'), and with 1 GB of RAM and only a 80 GB HDD in a matter of form factor small with a cheap food you get what you pay for.
    Personally - you better made to buy the parts from someone like new egg (if you are in the USA) and assembled the unit yourself. Basically, you try to make a silk on a scholarship...)

  • Satellite L300 PSLB8E - how to increase the ram clock speed

    I have a laptop which is equipped with 2 slots for ram PC2-6400
    1 - Samsung module M4 70T5663QZ3-CF7 [800 MHz] 2GB
    2 - Samsung module M4 70T2864QZ3-CF7 [800 MHz] 1 GB
    GPU: Intel GM45
    Processor: Intel Core 2 Duo T5870 Mobile @ 2000 MHz
    According to the manufacturer, this kit allows you to work with the 667/800 MHz memory speed, but the problem is that reference programs show the actual frequency of the ram at 399 MHz.

    Question No. 1:
    (a) why not clock the memory works in 800 MHz but only 399 MHz,
    (b) how to change to a 800 MHz

    Question No. 2:
    I'm going to buy a processor
    Penryn Core 2 Duo T9600 processor (1066 MHz FSB) (2.80 G) Hz or T9400 (2.53 G)
    and install it in the computer
    and increase the memory of 2 x 4 GB 800 MHz (8 GB)

    I explained that this possibility is provided for by the manufacturer according to the Maintenance Manual for:
    Toshiba computer
    Satellite L300/L305
    Satellite Pro L300
    EQUIUM L300
    SATEGO L300
    (PSLB8x/PSLB9x)
    (PSLBAx / PSLBBx)

    If this operation will help to improve system performance

    I put t know what programs you use and if it is good or not if this info can be good and perhaps not. I put t know. The fact is that you n t have one any influence on the functionality of memory and I doubt that you can do something and change some values.

    Exact specification for laptop laptop does not for me but I think that Satellite L300 must have Intel GM45 chipset and I presume that for your motherboard FSB is 667 MHz. You can improve up to 8 GB and compatible 4 GB RAM module has PA3670U-1M4G part number.

    Upgrade CPU on Satellite L300? I put t know man. A friend of mine has this model of laptop and I don t know if it's the right decision to spend money to upgrade this old model of laptop budget.

    Hello

    Shared graphics memory is controlled by GPU driver. You cannot add or edit it manually.

    More depends on the Windows OS you use, because the 32-bit system can manage max 3.2 GB of system memory.

    For example:

    * (32 bit OS) *.
    System memory: 2GB | 4 GB
    Dedicated video memory: 128 MB | 128 MB
    Shared system memory: 702MB | 1214 MB
    TOTAL available graphics memory: 830MB | 1342 MB

    * (64 bit OS) *.
    System memory: 2GB | 4 GB
    Dedicated video memory: 128 MB | 128 MB
    Shared system memory: 702MB | 1631 MB
    TOTAL available graphics memory: 830MB | 1759 MB

    Hope I could help you

    Hello

    In the specification of [Toshiba P305-8915 | http://www.csd.toshiba.com/cgi-bin/tais/support/jsp/modelContent.jsp?ct=DL&os=&category=&moid=2234100& rpn = PSPCCU & modelFilter = & SelCategorie = 3 & selFamily = 10 73768663] I saw grapich memory could be changed, but my question is how to do this? I have search and I can not find it.

    Ideas to change the graphics memory?

    As far as I know shared memory cannot be set by the laptop user. It depends on the RAM upgrade. With more RAM, graphics card will use more memory for the graphics operation.

    As you can see in the specs that your laptop can be upgraded up to 8 GB of RAM.

  • How to increase the video memory shared on Portege M100

    I have a Portege M100 and I would like to increase the shared video memory. In the technical documentation: 16-64MB shared video memory
    I have 768 MB of RAM
    but he can't do it in the Bios or Windows.
    where can I do it?

    (I'm french, sorry for the bad English)

    Hello

    As far as I know this laptop has an Intel graphics card.
    for example on an ATI card graphics it is possible to set manually shared memory, but on an Intel shared memory graphics card will be determined automatically.
    That's why you can't find any options to change this value.

  • Satellite A200 - how to increase the graphics memory?

    Hi, another question.

    I am unsing an A200-1CC, it's an Intel 945 Express Chipset Family settled. I tried to install a game that requires memory graph 256Motets. I received an error message "Shadow Pixel 1.1" maybe not supproted... and the page the maanufactured FAQ told me be sure to habe 256 MB in use.

    The A200-1CC has a 1024 MB of RAM and uses only a little over 100 MB memory graphics. I have check the Intel web page. My 945 Chipset supports Pixel of the shadow; and memory maximum grpahics used in 256 MB. So I increased my mother-2048 MB memory card today. However; It shows still 122 MB graphics memory in use. Page intel says that sometimes you can adjust the DMTV in bios, but that does not apply to my system.

    Any chance to get used to 256 MB graphics memory? -I use a Vista system...?

    Thanks in advance for any idea you may have.

    ;-) Ingo

    Hello!

    No, you can increase the video RAM and there is no option to change this.
    The video RAM will be assigned automatically, but you can t change that.

    I know this good news of aren t but in my opinion the Intel graphic card is not designed for games. An nVidia or ATI card graphics would be a better solution for the game.

  • HP Pavilion g7-1219wm how to increase the video memory.

    Hello

    Question is simple. but the answer is impossible as HP make it harder for us to be able to take advantage of its total capacity on the products that we buy from them.

    was announce on this computer laptop specifications that the video memory can be up to 1973 MB.

    memory dedicated only 384 MB and can not be change, why shops you can use up to 1973 MB. Which for me is false adverticement other wise, they explain how you can get this amount of RAM.

    If some now knows it please explain and post in this forum.

    Thank you

    Jred452

    Hello:

    In fact, the answer is simple.

    Change video memory cannot be done by any means by the user.

    Video memory mapping is automatically assigned.

    The announced video memory is correct if the video card has to use the shared PC system memory.

    Go to your windows experience index window and click on the detailed report.

    It will show you how many dedicated graphic memory it is, it is the amount of system memory dedicated (normally the zero with a discreet graphics card) and the amount of system memory is available for the video card.

    This is whence your 'until 1973 Mo"- additional system memory that can be automatically assigned to the video card if necessary.
