Windows 7: Cant set overvoltage for Intel e8400

Cant set overvoltage for Intel e8400

Hi guys,

Been a long time since my last post, years it seems, but less on that matter:

I tried to overclock my Intel e8400 from the stock 3.0ghz to the "internet proven safe" 3.6ghz.

I have set the timings for the Ram modules to 5-5-5-15, and set them to a 6:5 auto ratio with the FSB clock so they would clock as the CPU does.

I have set the voltage for the vcore to Auto and it seemed to work until reaching a limit that is 3.5ghz (or 389x9), but upon raising the FSB clock to 400mhz the system became unstable in Linpack, Became BSODing and lowering the multiplier to 6x and the clock to 2.4ghz(400x6).

I have then decided to change the vCore from the Auto setting to a manual 1.3v. After booting the voltage didnt change from the one Auto set from the bios for the 3.5ghz mark(which was 1.294v), and it obviously started BSODing in Linpack as well).

I tried raising it to a 1.33v vcore and 1.24 for CPU Termination for added stability, but the clocks still didnt change. Even tried raising the voltage for the Ram modules from 1.8v to 1.84 but no dice.

Any suggestions, or is 3.5ghz the most upper maximum of my system? Why cant i overvoltage my CPU over 1.29v? Could it be due to the FSB:RAM ratio?

EDIT: It seems that setting the FSB:RAM ratio to 1:1 solved the problem. Both the FSB and RAM are working at a steady 400mhz, with good system stability.
