ok, here's the problem, I can change the multipliers in bios now. I don't understand why, but for some reason I go to 11.5 and it's fine (that's stock for my 1800+), but when I go to 12 it boots back up at 11... I can change the multipliers in the lower ranges (below 11.5), but it can't, for some reason go any higher. My board is the XP333-R, and I've got the voltage high enough to handle this... 1.95. I also don't understand why the multiplier seems off normally. I adjust it (even in the lower ranges), and it always seems a little off. not by a whole half a multiplier, and not by the round-off error produced by an unconsistant FSB, but like by a signifigant ammount. I think my unlock was clean, I can see no causes of error in my job... well, I'm gonna retry it, but I think it's fine. Any help is appreciated, thx.
