(2x2GB) Corsair Dominator DDR2 PC2-8500 1066
XFX GTX 260 (216) Black Edition PCI-E Graphics Card
Corsair 620W HX Modular PSU - ATX12V v2.2 APFC
Coolermaster Cosmos RC-1000 Full Tower Case
Western Digital WD6400AAKS 640GB Hard Drive
Zalman CNPS 9700 LED
I've been running the system for just over a week now, and it's running very sweet... My stock 3D Mark06 score is 14302...
Anyway I want to get a nice overclock for 24/7 use, I'm aiming for 3.6GHz...
So far i've managed to get 3.0GHz which increased my 3D Mark06 score to 15210, and 3.2GHz which increased my 3D Mark06 score to 15808 these are both rock solid stable...
On the above 2 settings, I only changed the voltage for CPU to 1.2250v and the DRAM to 2.0v everything else was set to Auto...
After reading I found the board likes to over-volt when the voltages are set to auto, so for my 3.4Ghz I decided to put all the voltages in my self...
I then tried 3.4GHz which increased my 3D Mark06 score to 17048, but this failed Prime95 on work thread 1, running a Torture Test (in-place large FFTs) after 2 hours...
Here's how I set the Bios for 3.4Ghz, any ideas what to change to increase stabillity?
