Known 8800Ultra problems

[eitai2001]

Hi.

My client has a Asus 8800 Ultra.
When he plays games, it just plays fine for a while and then just hangs ... and in Vista, you can get back to desktop. If you wait long enough, it comes back then hangs again almost instantly afterwords.
He had a XFX 8800 Ultra XXX before that, and we thought it was an overclocking problem ... but the overclocked card did the same thing ... only quicker.
We have swopped every other component except the Processor and drives ... which we can see are not the problem.
It seems to be something with the gfx card.
Its not overheating either.
The rest of his system is:
Gigabye GA-590SLI-S%
AMD FX62
Transcend Axe Ram 2x1GB 4 4 4 12 DDR 800
700W Thermaltake Tough Power (we changed this too)

I plugged it into a UPS to prevent variable current into the PSU

Any ideas?

I have read of a problem with the drivers for the 8800 range of GPUs that involve a memory leak. Have you tried the newest driver?

This sounds like a driver issue with Vista. I have been reading a lot about this, and there is no solution. Getting an ATI seems to be the only option/fix.

We have tried, old new and beta drivers. The issue is not purely with Vista ... does the same in XP ... except in Vista we can get back to desktop ... in XP we have to reboot.
It also seems to me that it has something to do with the memory or memory buffer.

Make sure your motherboard properly supports the card. I had an issue where my old mobo didn't. PC would boot but as soon as I tried to run any 3D apps it would crash. Took me a lot of digging to find out the mobo didn't support the 8800.

Same problem with all the games?

The latest Nvidia beta driver come out on Monday, it was supposed to fix a related issue with the Memory Manager, I'd try that out.

Thanks ... will let my client know to try it out.
Also ... I know that this board "usually" supports the 8800.

There is nothing wrong with the hardware (mobo or 8800), it's an issue with microsoft OS and Nvidia drivers.

Did your client install the 2 hotfixes that MS released for vista which deals with memory issues??

Also does your psu have the 2 pci e power connectors connected to the card . If it doesn't this could mean the card is being under powered.

Not sure about the hotfixes ... will tell him to check it out ... the PSU is a Thermaltake 700w Tough Power ... it has 4 PCI-E Power Connectors for SLI ... I even borrowed a Gigabyte Odin 800W to try it out ... same cr@p
