PNY 8400GS, is it 256MB or 512MB ??

Hey guys quick question regarding a friends Geforce 8400 GS 256MB PCIex card.

This is retailed as a 256MB card, with various online comments/specs stating it 'supports 512MB'

Windows reports this card as 512MB .. !!

Whats the deal ?

More about 8400gs 256mb 512mb
  1. Maybe the it takes up some RAM. (check if there is 256mb ram missing) or its just a mistake in shipping.
  2. According to the guys in green, that card can only have 256 MB.

    http://www.nvidia.com/object/geforce_8400.html

    TurboCache is listed as one of the "features" available on an 8000 series card so perhaps it IS possible that the card's drivers can address 512 MB... just only 256 MB will be physically located on the card. That said... please tell me your friend isn't a gamer. That card is junk for games.
  3. sure not a gamer with that card, no just a basic internet user.

    The system seems to report the full amount of RAM, so it doesn't look like the video card had taken an extra 256MB from system.

    And as it's a PCI express card and not AGP, there was no BIOS option for AGP apature size, or other settings to use "shared video memory"

    I'm just wondering if it was a freak of nature, or a mistake on the production line.
    It's just the comments I found about "supports 512MB" that I wonder what it means.
  4. Can you link to some of the online comments/postings you referenced?
  5. New egg lists several brands "Supporting 512MB"
    http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&DEPA=0&Description=8400gs

    While some vendors are offering to-spec cards, some are typically offering overclocked or otherwise enhanced editions. XFX, for instance, is offering a GeForce 8400GS with support for 512MB of DDR2 and a 990MHz shader clock rate.

  6. It only has 256mb on it. The other 256 is from a feature called NVIDIA TurboCache. http://www.nvidia.com/page/turbocache.html

    "How Does it Work?
    The revolutionary TurboCache technology utilizes the additional bandwidth of the PCI Express graphics bus to reach higher levels of graphics performance than traditional video memory solutions, delivering the performance and features you expect from NVIDIA graphics hardware. By allowing the graphics processing unit (GPU) to share the capacity and bandwidth of dedicated video memory and dynamically available system memory, TurboCache turbocharges performance and provides larger total graphics memory."

    I actually have a 8400gs in one of my computers. It isn't half bad at 3d games at the lowest settings. But if you expect to play any 3d games in the future you might want to go at least 1 card higher.
  7. Thanks for the answer, it just seemed wierd as it didn't seem to take system memory.

    Guees it takes it as required (in-game), so at idle when I check the system memory, it all appears to be there.

    Yeah it's not really for gaming anyway, it a basic 'general use' PC.

    Thanks again

  9. You do realize they only have a 64 bit memory bus also.
    The 1st card I had in my system when I got it was a 7300LE 256mb (advertised as 256mb card)
    I was surprised to find out what it really was:
    128mb dedicated on-board memory
    128mb system memory (to get the 256mb)
    said it could go up to 512mb (feature of the card)
    so what I had was a:
    512mb card with a 64 bit memory bus using 384mb of my system memory to get the 512mb
    TurboCache = TurboTrash

    Personally i want the ram on the card and the systemram to stay differant but it seems that both camps are going with it.soon you will need a MOBO to take 6 Gig of ram 4 for Vista(2 for it to waste tying it up doing background stuff)and 2 to use and 2 for the gpu to nick.

  11. I'm still pondering when I get the 8800GT if I need 512 or is 256 enough. Some think it's overkill but I would rather have enough than not enough unless it's a hinderance.

  12. Are you serious? Its an 8400. Who cares how much RAM is on the card!
  13. Stay far away from PNY, got a 7900GS and it's crap....
  14. lol I hear ya guys,

    Like I said it was a basic internet PC, nothing fancy.

    I was just curious about the amount of RAM it was reporting, but it's not a gaming machine.

    Thanks for your help.
