Overclocking on an Asus a7v8x-mx

[thermalpaste]

I have an athlon-xp 2000+ with an asus a7v8x-mx motherboard. THe board has dip-switches that let you either select an fsb of 100/133/166. Whenever I select the 166fsb, it detects my processor as a 2600+ which is absolutely fine, but after the post screen windows-xp doesn't boot up. Is it because the PCI bus exceeds 33mhz?
Has anybody overclocked on this particular board?

I've never overclocked on that particular board, but you'll know whether or not it has an agp/pci lock by going into the bios and seeing if it will let you set the agp bus speed to a specific value. If it doesn't, it probably doesn't have a lock.

no, it doesn't. I just discovered that I can overide the PLL settings using software and overclock it. But the moment the PCI bus goes above 35 Mhz, the PC restarts.

I'm running my PCI bus at 37 mhz on a A7V8X board... I'm guessing it's your processor that's limiting your overclock. My 2000+ (Palomino core) won't go above 147 mhz FSB. I'm running steady at 145 FSB though.

The board does not have a PCI bus master lock. It does however have different PCI bus frequency divisors as I'm sure you can see in the BIOS. When raising the FSB to 150 the 1/5 divisor kicks in (making your PCI bus run at 30 mhz) but unfortunately there is no 1/6 divisor (not sure about your mx board though) on the A7V8X. That's what's limiting this boards overclocking potential.
