    OK you can get over 500MHz using a decent air cooler on the NB. The trick is a few extra tenths of volts on the chip, and things are safe so long as you keep it cool. BIOS versions 1.5v and 1.9v are good for this too. The phase cooling was there just to get a WR for the FSB speed

    BIOS 1.9v, wtf? hehe *edit* - Nvm, you meant BIOS 1.5 + 1.9v on vmch right?

    vmch mod is a must on this board, BIOS won't give more than 1.45v... I'm seriously considering this, and of course will buy better cooling.

    Out of curiosity: how high was ur vichio?

    Check FUGGERS thread, its the bios found in there.

    Not sure if Johnny found the same, but anything above 1.5v on vichio makes things worse for me

    No I was actually pointing out there are two good BIOS version 1.5 and the beta 1.9. the vmch mod is definately needed, running mine on air about 1.6-1.7volts iirc. vichio works best at 1.5v as Highland3r said we both found that at uber high FSB is hampers the clocks if you up the voltage from 1.5volts.

    Had no idea there was this beta 1.9 version... Is it better than 1.5? I'll try to find FUGGER's thread, but if anyone has a link I'd appreciate it

    Will also look for AB9's vmods, I think someone already posted here in XS, I remember seeing it once.

    And weir,d vichio actually helped a bit when I tried to get 450 fsb stable... But I'll stick to 1.5v

    Thanks for the help guys, when (and if) I mod the board I'll post the results here, I see my e6300 crying already!
