Some of you might already know this, this is for those who might not. I have been overclocking on a EP45-UD3R for more than a year now. I've always kept the BIOS that came with my board(F5) as it caused me no considerable problems.
I bought a Q9550 about a month ago and overclocked it easily to 4Ghz 471x8.5 and was quite satisfied for a while... We all know what happens next, the need to go further. It seemed by board would not boot and ounce past 4ghz with a 471 fsb even though I was running relatively low volts to achieve 4ghz (1.31vcore). The FSB wall seemed unbreakable no matter how many volts I threw at it.
For some reason I had the idea last night to update the BIOS on my mobo to F11. After the bios update, I could boot into windows at 4.25ghz with a 500fsb! So I tried a 533fsb, bam, booted into windows at 4.5ghz at 1.31vcore. Now these clocks weren't stable, but it goes to show that the FSB "moat" I was running into before was evaporated by this BIOS update. Hope this helps some of you on your quest for high clocks!!
