I have just bought a celeron 600 (cCO stepping) and an asus FCPGA slotket. I put them into my abit BH6 (v1.0X and ss bios) and ended up with no post or anything at all. The drives fans etc were all on but there was no signal on the monitor and no reassuring startup beep signifying a cold bootup and all was well. The voltage was set to cpu default(1.70v) on the slotket and everything else is fine with the system because I put my 550 katmai back in and everything posted and booted normally. What could cause this? Has anybody run into this problem before? I'm hoping that its a bad slotket not a bad cpu because of the trouble I went to to find a cCO stepping 600(they're being discontinued, supposedly). I was thinking there was a voltage problem but I've heard people with the same board that I have having no problem putting a celeron into a v1.0 BH6, actually at firingsquad.com they did the exact thing I'm trying and were completely successful with little trouble and an old bios that did not support cellermines. I'm itching to overclock this thing. Thanks for any input you can give me.
