Temperature for 6800

Hi folks.
I have a problem with my comp completely locking up so I have to restart. It only happens under heavy workload like 3DMark. Often it happens again just after the restart so I believe it can be a temperature problem.

I have an Athlon2600+ that goes up to about 55degrees C as maximum. It should be able to handle that, right?

Is it possible that my gfx Inno 3D 6800 128MB is overheating? I have a chassi fan but it is not directed towards the gfx card.

How can I test this?

Appreciate any help.

55c is fine for your cpu.
There could be a number of things that are causing restarts when your computer is under load.
What are your 6800 temps?
It could also be your PSU, what brand of PSU do you have and what is the wattage?

For video card temps, right click on your desktop, select "NVIDIA Display" and then your monitor. Then from the Nvidia control panel select "temperature settings" to see GPU core and ambient temperatures displayed. Note that these cards cool down from their max load temp in a matter of seconds, so you have to use a test (like rthdribl) which allows you to watch the temp while it's running.

I think that unless you're using a big overclock, PSU and other issues are more likely cause. I agree that 55C shouldn't be a problem for your CPU.
 
Ok thanks for the info. I thought it was the temp because it often happens several times after each other, when the temp has risen. I have formatted and reinstalled winXP so it should be a hardware problem. My psu is a cheap one but has 400W so I think it should be adequate.
How high temp should the gfx be able to handle? Using rthdribl mine got up to 70C without any problems.
I have a ASUS A7V8X-X mboard and it says on their site that "Note: PC3200 Max. to 2 banks only; PC2700 Max. to 4 banks only)"
I have 512 PC2700 and 512 PC3200 running at 333MHz. Shouldnt be a problem, right?

The PSU may be a factor. The rated wattage doesn't mean too much. More emphasis should be placed on quality (stability of voltages, etc.) and the available current, particularly at 12v for the video. If you have access to another high-quality power supply you might swap to see if things improve. Or if you or a friend have another computer w/high-quality power, swap the card and run the same apps to test it.

The GPU should be able to handle high temps, over 100C by design, as I recall. The cards will throttle automatically above a certain level. In the case of the 6800's, according to the temp settings tab of nvidia control panel, that level is an incredible 135C. Running rthdribl, my GPU gets to about 80C and the mfr said that's no problem. I'll take their word for it, but if it was much higher I'm not sure I would be comfortable. Your temp sounds cool by comparison. As a matter of fact, if you're able to run rthdribl for a good while w/out crashing, that goes a long way toward eliminating GPU heat as the culprit since not much stresses/heats it more than that test.

Another area for investigation is the memory. Have you run memtest on your current configuration to see if it's stable? Try running with one module installed at a time and see if there is an improvement. Some motherboards get touchy w/mismatched modules.

Is this a new machine? If not, did you use Driver Cleaner or some other app to remove the old video drivers? That could be a factor. Also, do you have your latest bios and chipset drivers installed? Also check your VGA settings in bios. You might do a forum or Google search to see what's recommended for your system. There are a lot of people on this forum who know all about this and have posted before.

I hope that this response is not to long-winded.
 
And if none of that works, I see that there is a 23-page sticky thread on this subject in the nvnews.net GeForce 6 forum.
