If so can you get the mobo stable at high FSBs when running the 5:4 dividor? ive been assusrd this board will do 290FSB odd as it was tested before i bought it.
when using this divider i get instability at over 250FSB.

Using the ddr 400 mode i can top out at 256MHz but then the ram tops out at 510MHz, im pretty sure theres more in the CPU but the mobo is holding me back.

Also at 5:4 ratio PAT is disabled, is this normal for 875 boards?
