So, I have bee having some issues with random crashes. Always happens when playing a graphically intensive game and only when SLi is enabled. Cruising along at 60fps then bam...a drop to between 1-4 fps then a BSOD and restart moments later.
GPU temp never climbs above 65c
CPU temp never hits 45c
Using Rivatuner I locked in the GPU fans at 100% and that made little dif.
On a whim I decided to take a peek inside, make sure all fans were workin and clean and such and I noticed something. My PSU only has 2 6pin connectors and my 8800s require 4. So what I did (without really realizing it) was just used the "molex combiners" that came with to turn two 4 pin molex into a 6pin power connector (I did this twice to get the other two 6pin connectors that I needed and each time i did it thats the only thing on that rail....didne plug any other components in).
What I noticed was that the two true 6pin connectors were plugged into my top card and the "fake" ones were on the bottom one. So just for fun I split em up. A real and "fake" on top, and the same down below.
Booted up and so far haven't had a single crash. The best way to crash the system before was to use Rivatuner to bump up the cards to 600/950 speeds.....that would lock er up FAST. Now the thing runs just fine at 650/1000.
So, could that really have solved the problem?? What gives?!?!
