The later Bios's dont allow a very high FSB which no good for me as my E6300 has a multi of 7 . The 0401 Bios lets me hit 3.4ghz but the 0801 bios limits me to 3ghz.
you also need to whack the full amount of volts on this mobo if you want a high fsb and then it needs active cooling.

Has anyone tried high speed memory in this board? With the price of the 1150MHz stuff coming down I'm getting tempted....
Getting a good overclock is not guaranteed. The CPU, motherboard, RAM and the loose nut behind the keyboard must all be just right to get the optimal overclock. The P5N-E SLi is a great dual-core motherboard, but it's 3-phase VRM struggles with Quad-Cores, not least because of the truly horrible Vdroop. Quads suck power and you need a motherboard that can deliver power smoothly and consistently, which is something the P5N-E SLI struggles to do unless you really crank up the volts and, as pegasus1 says, actively cool the Northbridge.
Given the fact that the latest BIOS is a beta, I'm hoping that means there will be another one on the way at some point. With 0801 and 0703 my overclock is severely limited, and while that is fine with my current 0608, my RAM doesn't seem stable even at stock speeds.
I am using the original bios it came with 
It runs stable at 3.4ghz. I did run it at 3.6 but was worried about the amount of volts I had to send thru the cpu which was running too hot for my liking. I thought as its so stable I didnt want to break anything upgrading the bios for no reason.
One quick question tho. Could someone confirm if you can boot from a HDD connected thru one of the USB ports?

Well an update
Left pc on overnight as usual and it was frozen when i got up
Rebooted and it froze again within half an hour.
Then i tried 0703 and couldnt even get to windows with that one so ive had to go back to 0608.
Luckily Q6600 support was added in 0608

For me the later bios's didnt bring anything usefull, i spose i would only update if i wanted 2 x 2gig mem support but then id need a CPU with a higher multi to get a decent OC.
gutted, keep trying though, I'm sure you will get your 4 sticks stable at their rated speed soon
I seem to be running quite nicely on this board.... it's nothing phenomenol - but ok for £60.
Upped the cpu to 333x9 (3GHz) & it's stable with 1.4V and 1.3XXV on the northbridge.
4x1GB Crucial Anniversary running @ 3-3-3-10 2T @ 667MHz

I was going to get one of these to mount on the northbridge heatsink - will it do the job?

It needs an 80mm fan to be honest, that fan produces virtually no air movement for the noise.
