My Rig:
CPU: Phenom II X6 1055T
Motherboard: Gigabyte GA-880GM-UD2H
Graphics: ATi Radeon Sapphire 5770
Memory: 8GB G-Skill Ripjaws DDR3
Cooling: Antec Kuhler H20 620, push/pull fan configuration on radiator
Case: Antec Nine Hundred with all fan slots filled (total of 7 fans in case, including the 2 on the radiator)
PSU: Antec 550W
When OC'd to 3.5GHz this thing idles at around 19-20C and hasn't ever gone above 42C under extended Prime95 load in a warm room.
The problem is, when I try to take the FSB even from 250MHz to 255MHz, the thing freezes when it tries to load Win7. I've tried every combination of voltages and multipliers for the NB, Memory and CPU that I can think of, and nothing fixes it. I'm pretty far from hitting the "heat wall," and I think my PSU should be adequate. I can't figure this out.
Here's the CPU-Z screencap for my CPU and memory (I did have to slightly overvolt it to even get it to 3.5GHz). Let me know if you need others.
I appreciate any tips you can give me. Thanks for reading.
