I got the same board and yes it is "quirky". Bought it not knowing all the problems that come with it. I have run pc133 and currently am running 2 512 2100 ddr and works fine. I maybe got one of the better ones (ifs thats possible). The one prob I do have though is the fsb changing back to 100 everyonce in awhile. This board has so many problems it has its own forum!. Check it out maybe it will help
