epox 8kha+ o/c non-compliance

[Bartokomus]

Just switched from the a7v266e to the Epox, and it is indeed faster seeming, but when i try to o/c through the bios, it only allows me to bump up the memory speed to 133; i did that through the jumpers and then selected 133 through the menu option. when i try to change the any other o/c value, it allows me then locks up on the subsequent reboot, irreguardless of the increment i chose(vcore, frequency, whatever). The funny thing is, I have the same board with a Xp 1600+, and i o/c 'd that thing to 1800, with memory speed of 143, and a high multiplier(sorry, forgot which one). anyways, i had a lot of flexibility, and played a lot. if anyone has any thoughts, i would be very greatful. thank you.
