Hi all,
First thanks in advance for any advice.
Heres my setup:
CPU: Pentium 805d 2600mhz OC'd to 3800mhz
RAM: PQI 2 1 gig sticks PC5400 ddr2 memory
Hard Drive: 2 Hitachi 7200 RPM drives as RAID
MB: Asus-p5nd2 SLI
CDR: 1 multi DV-everything
Power: 550w power supply
Cooling: Kingwin Water cooling
Video: Radeon x1800xt 256
Sound: Soundblaster Audigy 2
Fans: 2 80mm Fans
I'm a hardware guy--I generally know my stuff, but I'm truly stumped with this issue. This involves gaming and my girlfriend, so you can see the gravity of the situation.
The problem is this: When I play very intensive GPU 3d games, I get visual artifacting and crashing shortly thereafter. I am certain the GPU is crashing because it will play for a minute, GPU crashes, screen freezes, the "GPU recovery" screen comes up and says "we recovered your GPU crash".
Ok easy enough right? well, let me complicate things. I'm running a pentium 805d(2600mhz) @ 3800mhz. I am water cooled on my CPU and GPU. CPU temp is really great, the computer crashes about 70C on the button, it runs under load at about 50, currently 37. No CPU problems, to further that, I dropped the CPU to stock speed.
So the GPU when I put the water block on removed the heat sinks from the memory modules and I was able to run most intensive games like that for a long time (7 months or so), it concerned me that they had no heat dissipation, but games seemed to be fine with very minor visual artifacts. I eventually got RAM Sinks, and even those ram sinks were too hot to touch when they got going.
Enter Neverwinter Nights 2, the ONLY game my girlfriend will play with me, so you understand the critical importance of this! I basically get visual artifacting GALORE, then crash, usually within 5 minutes or so. The problem is that this has been an issue that has been getting progressively worse, now it is only a minute before the GPU crashes.
Heres a big sticking point though. I did a program called SpeedFan to see how much wattage my computer is consuming, sure its a hog. It calculated me to need an 880 watt power supply. Whoa! I have a nice 550. Could it be that during heavy load I do not have enough power going to the system? There are some indicators that this might be the case--once in a while my HD will lose power, a fan will not start up, and just recently, even though connected, my video card on boot said "You haven't connected your video card power supply!!". Maybe all loose wires, but..hmm, could a bigger or secondary power supply fix all this?
So my problem: why are my games crashing? My video card should NOT be effected by my CPU overclocking! Never ever crashes any other time. This visual artifacting happens in all GPU intensive games. Why would my GPU overheat at all--especially with water cooling! The core temp on the GPU is pretty cool according to ATI's own program, doesn't get much above 60, with water cooling stays below 60. Is it possible the RAM modules have degraded?
Basically: Why in gods name is a stock-speed video card crashing constantly--even when I make SURE things are cool!
Here is what I did to test things out:
1. Reinstalled the game many times, same results
2. Tried various drivers old and new
3. Stock-speed CPU to eliminate CPU possiblity
4. I removed the water cooling on the video card, put back on the brand new normal VGA cooling unit (fixed nothing)
5. Adjusted in game settings to test longevity before crash: higher settings, faster crash. Lower GPU settings, lasts a longer.
I'd appreciate ANY ideas here, and thanks for reading all this!
