Pin 21 question

[yipikayee]

* If I tape it, can I run Celeron333A at 100 Mhz BUS on any BX motherboard that supports only 66 and 100Mhz BUS?

* If I tape it, can I change CPU voltage?

* If I tape it, can I change multiplier like
3.5x100, 4x100, 4.5x100, 5x100?

From what I know, you CAN up the bus speed by interrupting pin 21. You can change voltage without it, and as for the multiplier, I believe you can futz with it without fooling with the pin, It's only for bus speed. But a word of advice. Rather than taping it, try enamel paint or epoxy. Tape gets things all gunked up.

Make sure it's pin b21.

Still won't be able to change clock multiplier. But voltage won't be a problem.

FYI, I've never had problems with clear scotch tape. No gunk, no mess.

I'd worry more about the paint scraping off when you insert the CPU, or leaving some paint pieces in your MB slot.

I would have to agree with Shocker, I have had B21 taped for 100mhz fsb and the pins for 2.2V for about 30 days now. I also used clear scotch tape with out problem.

Hope this helps!

The way to change the voltage is as follows:
Find the pins A119, B119 and A121, tape them, so they DON´T have ANY connection with the slot. Be sure that they are taped correctly, ´cuz if, i think but cant remember, pin B119 is conneted and the others are not, the CPU gets 2.6v!
With B119,A119 and A121 taped the CPU gets 2.2V. Just be sure to have good cooling!
