Does any overclocking expert know which 4 pins control the voltage on a Slot 1 Celeron? This is how you do it on a slot1 coppermine...

For slot 1 coppermine, the voltage selections are handled by pins A119, B119, A120, & B120 either grounded or open (giving you multiple voltage possibilities from 1.3V to 2.05V).

How does this work on a slot 1 celeron (and which pins do I need to tape to get 2.1V and 2.2V)? Thanks.

Actually, I found the solution at Tom's Hardware
Changing the Core Voltage on Any Slot1-Motherboard



<< As you can see, the default 2 V setting that is supplied by the CPU has already got VID0 'not connected', which cannot be changed by taping the pin. This is why you cannot reach 2.1 V or 2.3 V, both need VID0 'connected'. However, you can achieve 2.2 V, by covering the pins for VID2 - VID4 = A119, B119, A121. >>



So 2.2V should be easily done
