Freezing - finding the problem

post #1 of 3
Thread Starter 
I've experienced total system freeze ups recently when my system is under strain in a visually intensive game. I figured the issue was the GPU, and after some testing in Furmark it appeared that the GPU was indeed overheating and crashing.

However, I just got a new GPU tonight (HD 6950), and I still experienced a freeze up in a game. I decided to run a Prime95 test to get a better grasp on what's happening, and almost instantaneously my Worker #1 is failing, with the message "FATAL ERROR: Rounding was 0.49609375, expected less than 0.4." This is very odd, since my system has been totally stable for a couple of years now.

My system is
E8400 overclocked to 3.6 GHz
4GB OCZ Reaper PC2-6400
Radeon HD 6950
Asus P5N-D motherboard
650w Corsair PSU

My bios settings are
vcore 1.325
dram 2.11
ht 1.54
nb 1.54
sb auto
ram 4, 4, 4, 15, auto


Where do I even start to diagnose this problem?

I would start by putting all your bios settings back to stock to verify your overclock is not the problem.

I'm going to gradually work my way back towards that. I gave the vcore some more juice, upping it to 1.3625 volts, and after an hour of Prime95 testing it seems to be stable. I'm going to see if I still have any freezing issues at this point in game.
