At this point some pentiums are expensive, if you luck out your p133 may have open multipliers and be overclockable.

That is what I would do in your case.

Thanks for the help. Glad i have some options with CPU upgrades on this board.
I recently got myself a P1 133mhz (https://www.cpu-world.com/CPUs/Pentium/ ... -133).html) and im going to try and install it into my system. Gonna upgrade later on when i find myself a 166 or 200mhz P1 for sale at a reasonable price. Im thinking i'll stick with the pentium processors for my PC and not go crazy since I have no previous experience working on these older systems. I can build a new, modern system just fine, but there seem to be some key differences when working on new vs old systems.

As for installation of the 133mhz, how to i need to change the jumpers from how they are set as of now for my 100mhz?
Anything else i need to take into consideration or tweak before installing the 133 CPU?

Leave the 75/90/100 jumper where it is now (set to 100 = 66MHz FSB)
Leave BF1 as it is now.
Set BF0 to the opposite of what it is (can't make out if it's on 1-2 or 2-3 now, but whatever, you want the other option) for 2.0x multiplier.

That should give you 2.0x66=133MHz

Wouldn't adding a COASt module also increase performance?

Thanks, will try this out.
