Ok, with my locked xp2000+ AGOIA Y, I cant pass 144 fsb without getting a BSOD "Blue screen of death" saying memory dump or some crap. When I unlock, I can run a 12 multiplyer and get to 159 FSB but my chip runs at like 1624 mhz or something. So, my question is, why on a calculator does 12 x 159 = 1908, but on my computer it gives me 1624 mhz? The world may never know? I am using pc2100 ddr crucial ram with new ram sinks (extra mhz ) and my chip runs around 100 at load. I finnaly got my chip to unlock "correctly" and it registers as a 2000+ on post screen, but before it would say any model number xp except for the one I really have. Someone please help me!!
