Issue frequency RAM on CQ50 series

I have a pretty good knowledge of memory speeds when it comes to computers, but even I have a question about a specific memory. Maybe someone out there knows the answer.

My question is what is causing my main ram to laptops run at DDR2 - 667 mhz. I know for a fact it is PC2-6400 and is able to operate at an external speed of 800 mhz DDR2, but it won't. The default ram to 667 mhz no matter what I do.

The BIOS was my first choice to change this setting, but as usual the BIOS is locked.  Note to HP, you guys need to stop locking sections of the advanced features of the BIOS. This is a killer of the real deal for any future project, that I had to purchase more HP/Compaq computers. Not to mention the limitations, he puts on the system in general, in other words, it has a * beep * move on your part.

The system in question is the HP Compaq CQ50 and I modified it with updates of the game. Mainly changed the single core celeron 575 for a Core2Duo T7500 processor. The processor runs at a nominal speed of 800 mhz FSB and chipset GL40 says it supports up to bars of memory DDR2 800 mhz.

As for the memory, the system has had 2 gb (2x1gb) sticks to 667 mhz and I swapped those out for newer DDR2 800 mhz sticks (2x2gb) for a total of 4 GB. I was disappointed when then start the system and check cpu id to find the speed of the ram was the same, there was just more of it.

They are adapting sticks purchased at the same time and are registered as PC2-6400 (400 mhz), manufactured by Ramaxel technology with part RMN1740EF48D8W-800 number. Shot of another HP computer.

Which component on the system board is causing the RAM down the clock like that? I begin to suspect that the BIOS is the culprit because there is no advanced options, or really anything of use in there. Just, I want the memory runs at the expected speed, is there anything we can do about it?

System information:

Name: Compaq Presario CQ50 103WM (its been updated since the installed equipment factory)

Processor: Intel Core2Duo T7500 2.2 Ghz 6 MB cache FSB 800 mhz (original was core Intel Celeron 575)

Memory: 4 GB of DD2 at 800 mhz (operating at 667 for unknown reason) (has 2 GB of ddr2 667 orginially)

Graphics card: integrated Intel Mobile 4 series (GL40 Chipset) (also a serious bottleneck, and probably why the ram runs at the wrong frequency)

Operating system: Windows 7 Ultimate x 64 sp1

This seems to be the revelant information that future readers will have. If need more information I'll post on request. I feel there will be little or no help here, but I have to try. Otherwise no one would know that the question is there.

Hello:

This is not the info I've seen since the specifications of the Intel chipset on the link below... Max is at 667 MHz.

  • x 220 frequency RAM

    I know that the 220 x comes with DDR3 1333 Mhz RAM, so I got a second 4 GB module to add to the computer came with. I made sure the speed and timings were the same.

    However, looking at the memory in detail using hwinfo32, I see that samsung provided with computer memory supports 666,7 533,3, 400.0 and 333.3 frequencies.

    The memory module corsair that I just installed supports 400.0 533,3 and 666,7 alone. There is no support for 333,3.

    Could someonen please tell me more info on what that means and if it will affect me in any way?

    In addition, because I installed the new memory, my computer started hanging a few seconds once from time to time. This produces very rarely, maybe once every few hours, but when it's the computer becomes completely insensitive for 5 to 10 seconds. The hard disk LED flashes, but moving the mouse or typing on the keyboard causes no response - as if the computer is completely frozen. more 5-10 seconds later it again as if nothing happened.

    This only started happening after I installed the new memory - but it was in the same day that I tweaked my card to firx question 50 Hz Intel graphics drivers.

    Could someone tell me with certainty whether drivers intel or the new memory then occasional hanging happens?

    There is no errors in the event viewer that point to this and the built in windows memory diagnostic says my RAM is fine.

    Problem solved by the resettlement of these two memory modules. I initially do not introduce the new at bottom.

    Lack of support for the clock speed lower seems to be only a problem when the other memory is too slow and underclock the memory more quick to match. Since mine, both executed in their highest frequency, it will not be a problem.

    Memtest86 + finds no problems and performance with two sticks are a good bit more fast, with a value of $35.

  • In all of the possibly performance issues related RAM

    Hello

    Trying to play PC games recently, I had a few problems. Yesterday, I solved a problem of RAM where it says 16 GB installed but 3.46 GB usable by using msconfig. That has been corrected (apparently) However most of my games just get past title screens and even when they do they are slow as * / crash most of the time: nothing has changed.

    I have a GTX 770 so it is a recent issue, because he was working fine until last week. Driver is up-to-date as with all updated regularly through steam/uplay games. One glaring problem I see maybe I have 9 GB on Windows (c) to the left, but I really would not have thought that to be a problem.

    Any feedback would be greatly appreciated.

    Thank you

    Yes, you can switch to 16 GB of RAM. Windows 32 bit version cannot address more than 4 GB so to be able to use/uyilize 16 GB of RAM, you must run the 64 bit version of Windows. You can buy RAM from the reliable supplier or use the information, including prices, buy elsewhere:

  • Issue of RAM memory

    Hi, I have a 15' mid-2010 Macbook Pro with 8 GB 1067 MHz DDR3 RAM upgrade, I installed myself the 4 GB it had before... The problem is that I don't feel an optimization of the workflow, instead of that, sometimes I feel like it works more slowly than before, for example, where before he supported a lot of tracks in Garage Band, now it gets stuck and overloaded... any help how would I know if the RAM is OK , or maybe I did something wrong in the purchase/installation of memory?

  • Satellite 4090 on board the issue of RAM

    Hello.
    I have a S4090CDS/4.3 (PAS409EYV-EN9X,

    It would seem that the RAM is faulty (boots ok, as soon as you get 1/2 way through all the facilities you start getting memory errors type.).
    My question is, is the RAM on the main Board or on the processor board. Which is never someone has a part number or even a Board for sale.
    Thank you.

    RAM on most laptops is removable, as in desktop systems. There is a compartment memory inside of your laptop that you can open yourself, discovering the memory modules.

    You can test your existing RAM modules to find errors with MemTest (http://www.memtest86.com/). You just run the program, it copies itself on a floppy and with this diskette to start the tests.

    Your User Guide will be an article on how to install or replace a memory bar. Order number for a Toshiba memory of 128 MB RAM expansion is PAPA2062U. For more information about the Options for your laptop, you can visit this page: http://www.toshiba-europe.com/bv/computers/products/notebooks/satellite4090/index.shtm

    You can take a look at Kingston or Crucial to find the appropriate module for your laptop instead of buy a Toshiba that comes at a very heavy price because of the logo.

  • Issues upgrading RAM for Elite 8200 i7 Desktop SFF & CMT

    Hello.

    I recently bought 2 Elite 8200 i7... Lucky me.

    The first one is PSES, the second is a CMT. LTS such as a desktop computer, CMT and an ESX host.

    It's my plan.

    I will remove the current RAM of the CMT and put it in my SFF brining it up to 8GB.

    Then I'll buy 16 GB for the CMT...

    (1) what is the lowest latency CASE RAM can I buy for this machine? (240 pin DDR3 PC3 - 10600 1333 MHz)

    Secondly, when the 8 GB sticks are reasonably priced, I've fulfil the CMT, moving the 16 GB to the SFF.

    Given that the two boxes can use the same type of RAM...

    (2) what is the maximum RAM the WTO can take, I saw 32 GB and 16 GB quoted in different places.

    Thank you.

    Hello

    Today bought the 2 additional modules.

    32 GB works fine!

  • Related issue of RAM

    I have a G62-355DX with 3 GB of ram (I know not yet what brand of RAM is inside) then I saw this KINGSTON 4 GB ram compatible with my laptop. My question is, for example, the 1st brand of memory is SAMSUNG / 3GB (assume it is already installed when I bought my laptop), then I'll add more memory which is KINGSTON 4 GB. Will it work? SAMSUNG 3 GB + KINGSTON 4GB? or the RAM should be both the same brand?

    The mark usually doesn't matter, as long as they are at the same speed.

    Most probably the two ram slots are full, which means you will need to remove 1 module to install the new 4 GB, which means that you will destroy a part of the original memory.

    My G62 has 4 GB of HP, has a slot of 2 GB and 2 GB in the other location, yours is likely to 1 GB and 2 GB, so you would remove the 1 GB module to install the new 4 GB.

  • Issue of RAM Pavilion ze4900

    The ez4900 has a RAM in addition to what is in the Bay of RAM on the bottom of the chassis? Some laptops have little RAM soldered to the main Board, and their berries are to expand on that. The ez4900 has given me has no RAM card in the Bay. When turned on, it beeps 4 times but shows nothing on screen (screen remains black) and no action of the keyboard seems to have no effect. There is a blue light slow flashing on the bottom indicating suspend mode, and lights on the battery. Power supply has been checked and work. I haven't found an explanation to the line that can mean 4 beeps (or no beep codes for this model). So I wonder if the problem is that there is no RAM at all.

    Thank you!

    Wayne

    Thanks for the quick reply and which confirms my suspicions about the RAM. It makes sense to not use welded in RAM. I'll order a few sticks of 512 MB.

    Thanks again!

    do you, you insert the RAM sticks before or after the flash bios update? try to remove/replace the memory first.

    If it doesn't work, try this:
    Press windows + r, type "msconfig" > Startup tab > advanced options > mark 'Maximum memory' > select '2048 '.
    Restart your computer and check if it works.

  • After Effects CS5.5 - Performance very serious issues w/RAM Preview

    My system: Windows 7 Professional, two-processor Intel Xeon X 5650, 12 GB of RAM and a NVIDIA Quadro FX 4800.

    Problem: RAM Preview in CS5.5 give me less than 2 fps (Yes - two images per second). It's even with the simplest compositions. I created a project of 1080 p 23.976 with two solid layers simple and retouching position and scale values to one of them without other effects to be switched on. RAM Preview gives me 1.8 fps.

    I still have AE CS5 installed and it gives me strong and predictable results with RAM Preview. When I create a similar test inside the CS5 project, it creates the RAM Preview almost instantly and displays good real-time (23.976 fps).

    My settings for CS5 and CS5.5 are similar (and I tried many variations in my attempt to solve this problem).

    PREVIEWS

    Fast previews: Adaptive resolution limit 1/4

    Compatible OpenGL and two sub-options for active OpenGL.

    MEMORY and MULTIPROCESSING

    Reserved for other applications of RAM: 4 GB

    I tried different settings for multiprocessing, which translates the same less-than-2 fps previews RAM. Currently I have MP'ing activated with allocation of 1.5 GB per background CPU and real processor used is 4. Yet once, no matter what I set it to, I have the same problem of performance.

    On my screen magnification ratio setting, I use 25% and my Resolution/Down sample is on the quarter. In my preview, I tried setting my default resolution to "Auto" to "Quarter" without any difference.

    In short: on the same machine, RAM of AE CS5.5 preview offers terrible performance. Preview RAM CS5 offers excellent performance.

    Well, I got my answer and all is well in the world.

    After uninstalling all AJA (and even turn off my Kona card), I lived even horrible RAM previews. Then I Dove which was actually installed on my PC and here I found entries that refer to something as "Matrox Utils". I had not installed anything to do with Matrox. I'm not a big fan of the MXO2, but we have a few floating around the office and after asking around, I found my enemy - one of my co-workers used my machine when I was last week and it has installed and used the MXO2.

    So now I guess I have to install my AJA stuff and everything is good. Thanks a lot Szalam and Todd (and everyone else) for pointing me in the right direction!

  • The bloody sound issue with XP (DV7-2000 series)

    OK, if someone has managed to get IDT Audio Codec 100% functional under Windows XP?

    100%, I mean:
    -work the three speakers
    -headhones jack sound
    -cut the touch button turns on properly

    It's the box of dirty work, or nothing but box works...

    sp41398 - is the best driver to date (subwoofer does not work, always red button mute). The fate of two speakers and headphones.
    sp43935 - the last driver I could lay my hands on. Subwoofer only doesn't work, no sound from headphone jacks. The mute button is OK.

    The problem is obviously not in the drivers (*.sys, *.dll) themselves, but in the registry settings. Maybe the INF files are also well screwed upward. I tried to install sp43935 and returned to some settings in the registry as sp41398. I managed to make the speakers work with the subwoofer (with kind of a sound distortion at high volume levels, however). So I just replaced all the files *.inf sp43935 with sp41398 of the *.inf files and installed the drivers updated the. They acted exactly as sp41398 drivers, although the file *.sys and *.dll from across sp43935 most recent.

    Then? Any thoghts? Maybe someone has already solved the problem?

    I finally managed to mod the driver for Windows XP, so that it works almost perfectly.

    Indicator LED works properly, its fate of headphones, Speaker Subwoofer seems to work and no hack stupid devcon is required.

    The only problem now is that the IDT Control Panel works correctly. Well, already it did not work at all.

    If there are still users with Windows XP out there who want a better driver, let me know and I'll upload the driver somewhere.

  • Satellite L350-141 works with 4 GB of RAM?

    I want to improve my Satellite L350 up to 4 GB of RAM. BIOS accept 4096 MB.
    But I can't install an operating system (xp prof. or 32-bit vista)
    My L350 boot from CD DVD, but if the installation program does not start I have a reboot.

    My question is: will my Satellite L350-141 work with 4 GB of RAM?

    Hello

    I think that he should t be a problem with the 4 GB of RAM.

    But as you probably n t known, Microsoft Windows 32 bit OS cannot use the full 4 GB of RAM due to the limitation of the 32-bit operating system.
    Microsoft has published several articles and documents concerning the issue of RAM of 4 GB.
    If you want you can google for this question.

    Fact is that only Windows OS 64 bit (XP or Vista) would be able to use the full 4 GB of RAM.

    The BIOS and Chipset also support 4 GB of RAM to make sure that the laptop and windows would be able to use the full memory.
