Just setup this system yesterday and let it burn in for like...5 hours with sisoft. Overclocked it to 1750 so far (166 fsb sync with mem) on 2x256mb crucial pc2100, but the darn thing won't boot up with my pc3200 samsung stick. My samsung pc3200 boots up in my 8k7a rig with no problems also, can anyone give me some advice?
