I have 13 of these boards, and I've noticed something odd happening some of the time; The board will reset either the FSB overclock to normal, or it will reset the memory timings. If you go back into the BIOS after resetting the power, it will bring up everything correctly as it was set initally.

This will only happen once in a great while, but it can really set me back and I cannot find any information on why it would happen. All but one are running the latest BIOS revision, but it seems that all the previous revisions had the same problems.
