Thank you all for the information. This has been very helpful.
I also want to contribute back.
My 1st post in this forum.
I've spent whole day configuring the system.
I finally reach 5GHz and passed Intel Burn test.
RAM: 2x2GB OCZ3P2133C9LV4GK @ 2133
SeaSonic M12D SS-850 850W (Silver) - with 2 8pin power
Xigmatek Dark Knight cooler
HIS 6950 2GB (unlocked to 6970 and overclock a bit)
3dmark 11 hit around 5480.
I had to bump vcore to about 1.44, a bit over 1.5 when stress test.
However, this is too much heat core 1 & 2 are over 90C.
I guess I'll have to back down to around 4.8 Ghz @ 1.36V for daily use to get around 80C full load.
I'm using a different comp for this post to get the config.
Will post a screenshot after this.
Hope someone can give me some feedback on my config. Thanks
