CPU: E7200 vid=1.1375
MB: P45 UD3R, bios ver: F9
RAM: 2 X 2G of OCZ reaper 1066(5-5-5-15)
So, right now im running at a FSB of 500 with a multi of 8 to get 4.00Ghz on my C2D. All the setting are pretty much AUTO(lol yea) except vcore which is set to 1.3475 in the bios(1.312 CPUZ). Right now my system is 100% rock stable and I wanted to see if i could go further on the OC. So I lowered the FSB and put the multi to the max of 9.5X.
Im trying to go for 4.15 with the following bios settings:

but within 45Minutes of prime small FFTs i get rounding error. Anyone have any tips or pointers to make this OC more manual and stable? All help is appreciated. Am i hitting the max for the cpu or am I missing some settings?
Thanks!
