P5N-e SLI's weird FSB overclocks

I've been overclocking my cpu. I've been at it all day. I hit a wall at 2.6 and read online that my mobo had a memory problem from FSB 1200 to 1333.
1200FSB is were I hit the wall so I lowered my multiplier to 8 but the only OC I sould get to post was 1400x8(2.8) It was rock stable at stock voltage. I changed the multiplier to 9 and it booted to 3.15. I had to raise the voltage to 1.35 to get it stable.
I can not get any OC over 1200FSB to even post other than the above mentioned. I don't understand why my mobo is being so touchy.
I just got the latest bio's 1002 and its the same story. My temps never go above 61C after a hour of cpu burn-in.

Sorry for the long post and thanks for the help!

Hey,

I have a pretty similar combination running for over a year now. MSI P6N SLI FI (650 SLI also) and an E4300. At first I could do what I want but the system won´t run stable above 265 MHz FSB. I tried pretty much everything regarding Voltages, settings and checking for FSB holes.

Then I sat the FSB to 335 - I don´t remember why. But the system posted and ran stable. I played with the settings then and well - the system is running 100% stable for over a year now with FSB 340 at STOCK voltages for everything.

I figured out that I had to go over FSB 333 MHz to force the board to switch to that FSB strap. Your problem sound pretty similar to me - I suppose it wouldn´t hurt to try to go straigh to FSB 334 and look if it works. A good friend purchased the same system as me at the same time and what I did worked for both of our systems!

Greetz,

Bolle

Ok, that´s pretty strange... Did you also set the correct RAM settings, just to be sure that the resulting memory speed wasn´t the problem?
