I have some left over parts which I could use for upgrading my wife's computer. Those are Cedar Mill Celeron D 356 (3.33Ghz, 533 FSB) PCCHIPS P23G Motherboard 1GB of DDR1 PC3200 GEIL Memory She currently uses Athlon XP 1700+ (@ 2.17Ghz) I was going to overclock this Celeron D 356 but PCCHIPS Motherboard won't let me do it. On the same motherboard, I used to run E2160 1.8GHz @ 2.4Ghz by using BSEL Mod. I have been googling for BSEL Mod guide for Cedar Mill Celeron for the last several days, but it is nowhere to be found. Could it be because people are not interested in this old CPU or it is not possible to do BSEL mod on Cedar Mill? I want to know how I can push its 533Mhz FSB to 800Mhz. Please help me. Thanks.
