Sure could use some help here.

My new system consists of;
Abit AV8 with K8T800 chipset
2 512 Corsair 4000 DDR
2 Hitachi serial 120's striped
AMD64 3800
eVGA 6800 Ultra
580 watt modular power supply

The video card is using seperate molex power connectors, instead of the factory pig tailed system. Without any real tweaking it posts a 90.3 FPS Doom3 score. After playing Half Life2 for an hour, it locks up and reboots, then displays a screen that the video card doesn't have enough power. When this machine was first put together it had a 480 watt psu, so when that screen popped up, I said sure lets step up to the 580. Which btw you only plug the power cables you want to use with it, in the back of the psu. Sure helps keeping the wires tidy in the acrylic case.
I am starting to think this is a heat issue, before I change the bios or something I shouldn't, thought I would call on the "PR think tank".

It is most likely a heat issue. I had that problem when running 3dmark. I cleaned my heatsink and it worked perfectly fine.

OK my first question is which drivers, secondly did you completely remove old drivers, and also check to see if there is an available BIOS Flash for the 6800 to fix small bugs.

It's definatly a sensative card mate. Mine would give me voltage issues on my 420w Generic, hell, it wasn't too thrilled with my 500w X-Conn dill I used 2 cables, each plugged into its own special port on the back of the X-Conn. As far as heat goes. I dont have a case ATM (wink, giveaway, wink) so its all siting on my mobo's box, no fans on it at all; CPU is WC'ed but not the GPU, waitting on the brass maze 4 top for it., and my room goes from 35 F to 75 F in my room (open window cold boot to heat on & comp running all day).

My GPU has been telling me 50c Idle, 65c load for right now. I remeber when i was pushing the OC it seemed to give me crap at 80+c so check your card for that range.

I am at a loss here. Put 5 Stealth fans on it, two blowing in on the cards, one blowing out in the top, one out on the back and one blowing in in the front. The Hitachi drives are mounted in squirrel caged coolers blowing in. I bought a smoke test kit from a plumbing store and the air s exchanging and hauling @zz through the box. Installed a Zallman Flower CPU cooler. Updated the bios on the Abit board, used a utility to remove ALL of the Nvidia driver, then did a fresh install of the latest Nvidia driver.
After an hour of CS, it just locked up on me again
I have invested a couple bucks in this thing and feel that this should NOT be happening. Any other ideas?

Raise the AGP voltage to 1.8, make sure that AGP Spread Spectrum and VGA
BIOS Cacheable are disabled, and also ensure that fastwrites are disabled.

Last but not least, (and only for the time being, for testing purposes), set AGP to 4x.

If it still locks up after all that, I would consider returning for a replacement from another brand such as BFG.

Redigieren

If I ever see any signs of bugs in my stuff that I order I will immediately RMA.
With tons of products sold every day there will be duds out there. This one I feel is a dud.

My first video card I bought was an fx 5600 and the fan didnÂ’t work out of the box. So I just zip tied a case fan on it and called it good.

Tek, I just couldn't turn my stuff down that low. After further investigation, the PSU that was installed in the system was a 500 watt modular psu. The guy installed it because he thought it would look the best in the acrylic case, but did not listen to my caution of the low wattage. After I installed all the fans and a couple 120 Seagates for storage, when the computer first boots now I get the 'votage warning'. I have just ordered a Thermaltake 680 watt psu , that oughta take care care of the voltage issues. My only concern now is at full load wouldn't that power supply pull more than 6 amps? better check the breaker and circuit situation.

BTW with the settings turned down it only does 84.5 fps with the video stress test in the Counter Strike Source screen. When it is normal it does 134.5fps, heck of a difference....need more power
