View Full Version : I swear NV screwed up with the odd memory sizes (320, 640)

I've been betting that improper detection due to not being coded in the driver or whatever is making the 320mb 8800s to be detected as 512 because it is seen as >256. I think I've found a little proof:

I think really what that comes down to is the application just not detecting it correctly.

I dont think NV could make THAT big of a mistake
They leave the mistakes for drivers ;)

yeah my GTXs get detected as 1 gig when it's just 768, it's just the way the program is written

i have to agree, you cant blame NV for the developer coding short commings...

If this is the only short coming of the 8800 series, then I think it's safe to say that Nvidia has hit a homerun on this series of cards. I realize the drivers could be better, but the cards are still a spectacular achievement for Nvidia.

I think he's coupling this with the fact that many are experiencing memory leaks in the drivers when playing games like F.E.A.R.:

Up to 6 pages now and all G80 cards mentioned.

more like 15 pages

and a continued communication with XFX has only resulted in them saying "We cannot reproduce the issue... NVidia cannot reproduce the issue either.." etc etc. I've been offered an RMA but I highly doubt it is a problem with the hardware.

They can't reproduce the issue? Well I wonder what they're doing right.

Jackpot! And yea it is about 15 pages.

This is why I'm drawing this conclusion:
Well i'm having same problem with my Sparkle 8800GTS 320MB on WinXP with 158.19, 158.22 and 160.03 drivers. It seems to be somekind of memory buffer problem. I have noticed slowdowns in Oblivion and Test Drive Unlimited.

I made a screen (http://www.zone.ee/orbiklaps/pildid/memusage.jpg) of Riva Tuner video memory graph after Alt+tabing while playing Olbivion. At the time when slowdown begins, non-local video memory usage starts growing. But weird is that local video memory is not fully used up. Sudden downwalls at graph are spots while i alt+tabed out of the game and back to it. It seems flushing video memory buffer or smth.

This thing should be solved soon, it's getting annoying.

My theory is that applications are seeing that it has more memory than whats available. In the 320mb case being shown as 512, that's a 192mb deficit. Cards with 640/768mb don't see the issue as much because games aren't really taking advantage of more than 512mb yet like they have been with 256. The tool in my OP was the Ubisoft Detection Tool v1.7. It may come with other Ubisoft games. I would like for others to see what results are shown for them. I may try to contact Ubisoft to see if this is a known error and where the issue actually lies.

I never had any issues with this...Every game plays fast all the way through after 2 hours of playing it.

You have a GTX...this is more specifically geared towards the 320s.

If you buy a GTS 320mb card, you get what you pay for. Sorry. :(

Look on the bright side, it still beats the pants off of the 8600 GTS.

That's no excuse man.

Nope, it's something that they need to fix, and it even happens on the GTX. Happened on mine in both FEAR and Oblivion.
