Maximus II Formula w/ E8400 BIOS Settings
Hey all,

I just recently got an ASUS Maximus II Formula with an E8400 CPU, and I have been attempting to reach a stable 4GHZ OC like most of the people who have an E8400.

My computer specs are as follows:

Motherboard: ASUS Maximus II Formula
CPU: Intel E8400
RAM: G. Skill PC2-8000 2x2GB (4GB) (Capable of 2.1v)

I have the ZALMAN 9700 Cooler cooling the CPU, and I've been able to achieve a simple 3.6GHz on it with 400x9 settings in the BIOS w/ minimal voltage changes.

However, whenever i try going to 445x9 or even 500x8, with some voltage increases in the ranges of 1.34-1.38, one of the cores manages to continously fail in Prime95 running on Blend after about 30 minutes.

I guess the major question is, there are a whole lot of other voltage options to tweak on this motherboard, and I am unsure as to whether or not these other voltages need to be tweaked. Some examples of this are as follows:

CPU PLL Voltage
SB 1.5V
SB 1.1V

There are quite a few more, but I am not home this minute to record all of them down.

If none of these really need to be modified, should I just keep upping the VCORE to 1.4v and keep praying for a stable Prime95?

Any assistance on this would be appreciated.

I would really like to hear from others that have reached a 4GHz OC with an E8400 on a MAXIMUS II FORMULA or similar board, even a P35 would be fine :).

What kind of temps are you seeing? That would be the first thing I would be looking at.

What stepping is that e8400?

I have the same motherboard in a second PC I use. I found this thread very useful for starters.

I will check the stepping when I get home tonight.

I'm sorry for the delay, but I appreciate the responses.

45-50 Celsius

Stress Testing
50-55 Celsius

I will also check out that thread you sent.

Thanks!!! :)



Is it possible you can specify your motherboard settings?

I've been reading that thread and checking out what users are saying on it, but I'd like to see a template of things people are actually modifying so that I can narrow my research down to more specific things that need to be modified :).

Thanks again!

Yeah the stepping is E0.

I got the same MB & CPU. So far I've been able to run fully stable through 6 hrs of prime95 in blend @ 4005MHz (445x9) with the temps at 36-37C idle and 55-57C full load. I can't find yet an acceptable temp with a higher clock, I think i'll go liquid to shoot for 4.2Ghz. Anyway heres the settings I used (as shown in the BIOS):
Ratio CMOS Setting = 9.0
FSB Frequency = 445
CPU Voltage = 1.3125
CPU PLL Voltage = 1.5
FSB Termination Voltage = 1.32525
North Bridge Voltage = 1.1265
I forgot to write down the SB voltages, but i think they go like this:
sb1.1 = 1.79
sb1.5 = 1.50

Hope this helps you out and good luck.
