P5N-E SLI + 400Mhz FSB?

[starcraftfanatic]

I'm looking forward to OCing my E6750 to 3.2, and I was wondering whether my mobo will run ok at that speed. Will there be any problems?

I can't find a lot on that board. I would guess it will as a 650i. Might take some tweaking and work though.

Why don't you just try it and if it doesn't do it then quit?

whats the way to change the setttings to 400Mhz FSB and boot with it without saving it to the BIOS so if there's a problem, it will start up at 333?

There isn't.

You set 400 MHz FSB and then save it and it tries to load. If it doesn't POST you clear the CMOS and try again.

Go in 3-5 MHz increments... you'll be fine.

Will there be stability issues before it doesn't post. and do I have to press a button on the motherboard to reset it?

The stability issues will be in Windows and will either restart the computer or will cause other issues.

Read the sticky at the top of the thread about OCing. I was under the impression you had and were just asking if your board would do 400 MHz Bus.

I was just wondering how severe, I OCed my P4 to as far as the limited bios would go, and realized I wasn't getting sound, so I had to scale back, I was just wondering would I have to be running a few stability tests every time or whether the results will be obvious.

Every 5 MHz steps I run 10 minutes of Prime95. If I get no errors I'll reboot and add another 5 MHz.

When I get an error I bump up core voltage. If I get another I'll bump it up again. If I get another I drop the multiplier and see if it's something other than the CPU causing the problem at that speed.

Once I reach my goal I'll run Prime95 for 8 hours on SmallFFTs for CPU stability then 12 hours of Blend for overall stability.

Edit: This is the safe way. I really don't care and jumped from 266x9 -> 333x9 -> 400x8.
