Title: My video card...a Bug? Or mix up by the manufacturer.
Post by: EAD_Agamemnon on November 16, 2007, 10:40:47 pm
Back in May I bought an Athlon 4000 2.1 Ghz from DELL. With it I got a GeForce 7300 LE with 256mb.....now heres the strange part.

In dxdiag, under display, it shows the card type and name...but it shows the card memory as 512mb...whats up with that? On a computer my mom recently got (it arrived in the mail a couple days ago)....she has a GeForce 8300 GS with 128mb....and it TOO shows up as having 512 memory in dxdiag. Whats up with this?

Go fetch GPU-Z (http://www.techpowerup.com/gpuz/), install it, run it and check what it says about your GPU. Or RivaTuner or AtiTools or some other GPU-related tool that lets you observe the properties and settings of your card. It's a pretty much non-bribable in that regard, it should tell exactly what your GPU has eaten...

It is likely that both cards are set to borrow some of your system RAM ans use it as extra video memory as default *points finger at DELL* especially since both are budget cards... although especially for the 256MB one, I don't think it's actually necessary to dedicate system ram for it in addition to it's own memory. Donating system RAM for GPU usage is OK if you have *plenty* of RAM. If you don't, you might want to check in driver settings if you can find anything like that and possibly disable it, it'll free more system RAM for program usage which will likely end up improving performance more than using it as video memory. Anyway, if I'm not completely wrong, DXDiag only tells you how much VRAM is usable from the POV of the operating system, it doesn't separate the card's own and borrowed system RAM in that regard AFAIK...  so it's the most probably reason for this.

Other possibility is some driver conflict/bug, and the least likely possibility (especially since two different cards are doing this) is that someone in the manufacturing facilities has screwed up to your advantage and the cards actually have more memory than bargained for. It's very unlikely though, but screw-ups like that in smaller scale aren't unheard of - I personally have an XFX GeForce 7600 GT XXX-edition, which is supposed to be factory overclocked core to 590 MHz, but instead it's overclocked to 650 MHz, so I actually got more than I bargained for, and I'm not complaining. :p


EDIT: Also, this conversation might better belong to GenDisc or Gaming Discussion since it doesn't directly have anything to do with FreeSpace. :)

INFERNO! Our Last Best Hope for FreeSpace3

You might want to rephrase this sentiment. Not only does it open the whole FS3 can of worms and whether or not anything community-made could or should be called FS3, it also is kinda inconsiderate towards all other campaigns and mods that are not Inferno. Some might find it even downright insulting.

As Herra Tohtori said, the cards are almost certainly using Turbocache or something similar to pool off system memory, in addition to the onboard memory of the card. Different programs report such things differently.

I was about to move this to gaming but then I saw your edit on the Inferno thing, so I might as well leave it here for now. :p

Go fetch GPU-Z (http://www.techpowerup.com/gpuz/),

Thx for that... I meant to do this earlier, but you gave me the opportunity: I moved that link to my sig.  :yes:

It's Turbocache. I used to have it in my system. I recommend you switch out that 7300 immediately. Turbocache causes a lot of problems with some games like Half Life 2 or SWAT 4.
