Reducing Graphic Shared RAM by GeForce 8500GT

Hi all!
I have an Nvidia GeGorce 8500GT 512 MB Grafix card and 3.5 GB RAM. My Graphic card is using up my 0.75 GB RAM. is there any way to reduce this amount to 512 MB (0.5 GB)?
I m using Windows 7 x64 Ultimate.
Thank You

    how do u figure that, its a discrete video card it shouldnt use your system ram like onboard gpus. even then with an old system like that it wouldnt really make any difference. i had the same one with the 2.8ht for the mrs with web browsing it was slow! alot of old systems were a bit funny about ram configurations unlikely but possible
  2. You might be able to go into BIOS and disable the on chip graphics, not sure. Won't make much difference anyway.

    The System properties show that i have 2.25 GB of useable ram out of 3.5GB, (Even though 64bit Windows 7) and dxdiag my graphic ram is 1394 MB RAM...
    I really need that 0.75GB ram... i usually work with virtual machines and this much ram surely makes a difference...
    I'll try that disabling from bios, but i dont think it has that type of option...
    Thank You

  4. The system ram is not usable definitely not because of system shared RAM to graphics card. I have 8 GB of system RAM and my GTX 560 Ti has 1 GB of dedicated memory. In DXDIAG it shows that my graphics card ram is 4GB, but it doesn't hurt my system RAM:

    I see you mixed different size of ram sticks on your PC, try taking out the 512 MB one and check if it fixes it. Might be a faulty stick.
  5. It has been explained to me that the OS can allocate video RAM from system RAM but will release it if needed on other tasks.
    If you really think you need 750Kb of Ram, buy another 1GB stick and replace the 0.5 GB stick for proper dual channel operation.
  6. ok... nothing worked... and i can't buy a new RAM...
    Does Dedicating my 4GB USB for Ready Boost Help me out??
  7. *bad math... thats around 1.25GB og ram taken by my graphic card... isn't that too much?
  8. I repeat, ITS NOT taken by your graphics card. Something else is wrong. As I said, try 1 stick at the time and check if it's any of the stick's problem.
  9. no matter what ram i remove its always 2.25GB USABLE.... :cry: :cry:
  10. Did you try 1 stick at a time? Did computer work with all 4 sticks separately?
  11. no... 3 ram at a time were on the board... first removed one 512MB (still 2.25GB useable), then removed one 1GB again and again keeping the total Amount of ram to 2.5GB (still 2.25GB useable).
  12. Could you try it with 1 stick at a time?
  13. wouldnt that be too less to run Win 7 Ultimate 64 bit?? its req is 2GB ram...
    wouldn't hurt to try would it? :D
    Will try and tell the result
  14. The requirement is for smooth usage, but I once installed windows 7 32 bit (1 gb ram req) to laptop with 256 mb. Well, it lagged, but it did boot up!
  15. Here is the Result...

    1 GB Kingston Check: 1GB RAM USABLE
    GFX RAM: 754MB

    1 GB Samsung Check: 1GB RAM USABLE
    GFX RAM: 754MB

    1 GB Samsung Check: 1GB RAM USABLE
    GFX RAM: 754MB

    512 MB Kingston Check: 510MB RAM USABLE
    GFX RAM: 563MB

    All RAM Intact(3.5GB): 2.25GB USEABLE
    GFX RAM: 1394MB

    now what should i do... :/ :(
  16. I have the latest BIOS of the System...
  17. As DelroyMonjo pointed out, your operating system will automatically allocate system RAM for your graphics card. For NVidia cards, this is called TurboCache (AMD cards it's called HyperMemory). There may be a setting in BIOS that allows you to change or limit the amount Windows will allocate, but it's not necessary. If the system requires some of the RAM allocated, it takes it back.

  18. But 1.2GB is too much dude... What is RivaTuner? Does It Disable TurboCache?
  19. I have read that it takes up RAM when needed... But its Taking RAM before its needed!
  20. one more thing... 840MB is shared memory... if thats so then where is the rest 400MB?
