faulty gfx mem??? help

[omenire]

Been having probs with this card for months now, and I've hit a brick wall

now. Essentially the prob is, when playing games, I get about 10 mins into it

and the comp freezes, either returning to windows eventially or bsod with

0x00000050, 0x0000000a, or 0x0000001e stop errors, pointing to usually

either ntoskrnl.exe or nv4_disp.dll. I have reinstalled (then driver cleaner) my

mobo, gfx, and many other drivers, as well as software. As the dll in the stop

error nv4_disp is a gfx driver file, I have tried pretty much all available nvidia

drivers, several times, with diff setups with mobo drivers... all to no avail! I

have also tested the memory with memtest and it throws up faults, so i

swapped my crucial pro for my old ram, and it still throws up probs when

tested, hence I'm thinking gfx mem probs... Any ideas people??


Asus K8N nforce3 250g
Crucial 2x512 xms3200c2pro (at stock)
amd64 3400+m (at stock)
Gainward 6600gt gs 1960xp (at stock 500/900, enhanced 540/1150)
good psu 650w true power, braided

ps yes the fan is working and the power is attached to card, plus I just did a fresh reinstall of win2k pro, onto a diff hard drive ( and all drivers) and still get the same probs??!

What timings do you have the memory at, and have you tried increasing the DDR voltage at all?

[cloasters]

You could slow down from overclocked to stock and see if that helps.

Have you checked the temp of your video card ?

I have an ATI 9800 Pro that was running in my box and when I started playing it too kept flipping (returning to Windows) till I got thinking about the heat that that card produced; it gets its air from the inner of the case BUT it blows its hot air BACK in the case again. Not a good way of cooling things.

Then I got searching on the web and found an early version of the Arctic Cooling VGA Silencer ... It takes air from the case, cools the GPU, BUT then blows it out the back of the case into the room !!!

Anyway, since I mounted that on the card and some passive RAM coolers (heatsinks) it hasn't done that anymore !

OK first off, there is nothing wrong with your video card memory. If anything its your system memory or motherboard, but for the time being lets assume they are OK and try something else.

You said you have the power connected to your 6600GT, now what I want to know is did you use a dedicated molex line from your PSU to power the card, or did you use a shared one. Most Molex cables have 2 or more piggyback joins, so that one cable comming out of the PSU can be used to power multiple devices. For stability, and always better overclocking results, use a DEDICATED molex from your PSU, that is not plugged into anything else at all.

If that is already the case, then you might want to try another driver. The best driver package for you to be using is the 76.50 Valance Studios / Xtreme G modified set, which you can download from AOAFiles.com

Next, try removing one of your memory sticks. You are on a S754 board from memory, and they are always more stable running 1 stick than two, particularly at high speed. The fact that the memory can run at its stock speed, doesnt mean that the S754 CPU's onboard memory controller can handle TWO of those sticks at the same time, and they are already fast sticks, so I assume that could be your memory problem.

Remove 1 stick, and it should not have any memory errors, and if you want to run two sticks, use a 2T command rate, and reduced speed (166Mhz probably).
