Which processor would be the best to overclock??

[Blondell]

cC0 or cB0 stepping

P3-800
SL457/SL3XR cB0 S.E.C.C.2 Vcc Core Voltage - 1.65 V

SL463/SL3Y3 cB0 FC-PGA Vcc Core Voltage - 1.65 V

SL4MA/SL4CE cC0 FC-PGA Vcc Core Voltage - 1.70 V

SL4KF/SL4BY cC0 S.E.C.C.2 Vcc Core Voltage - 1.70 V

Go with the choice 3 or 4. There's no reason for you go with the cB0s. so good luck.

I have the 800 bC0 secc2 and can get 130mhz fsb or 1040mhz max from it.
I am pretty sure the cC0 would do better.
I do not think the secc2 or pga form would make a difference unless you are using a pga in a secc2 board then I think the pga would do slightly worse.
