Overclocking Pentium M (banias)

[robertk2012]

I got a couple of these and would like to see how high I can overclock them.

Edit: I only have the chips so I will be building a complete system around them. No advice needed on PSU, ram, hard drives, or case just on a motherboard and potential problems I might run into.

As far as form factor I dont care.

What motherboard would you reccomend?
I dont want to spend a ton of money on a motherboard if I dont have to.

Any advice?

There is pin mod for them for 533 FSB last time i checked.

For extreme overclocking of Pentium M, the best setup would be an Asus CT479 adaptor board and an Asus P4P800/P4C800 type motherboard, modded for voltage. Check out Xtreme Systems because a lot of like minded people hang out there. I do know that you're not going to set any speed records with a Banias. IIRC the top stock speed was 1.7GHz so the 1.7-2.0GHz range is probably the limit for "easy" overclocks, beyond which you'll need to go water cooled or some kind of freezing (LN2, phase, dry ice, peltier). Dothans seem to get much higher, hitting 2.5+GHz on air cooling and some have gotten 3GHz+ freezing them. Next chip beyond Dothan is Yonah, and those crazy foo's are hitting 3.5GHz+ with extreme cooling.

There really isnt a cheap solution for using these on a desktop is there?

Im really not looking to set any speed records, I was really just wanting to play around with it.

There are no cheap solutions for a Pentium M desktop. S479 boards are expensive and to use the CT479 you need to buy that and an appropriate Asus board. It's very easy to do the pin-mod to 533MHz FSB though. I have a Dothan 1.5GHz running at 2.0GHz simply by doing the pin mod.

The bad side about using the CT479 is that your aftermarket cooling options are limited. But definatley look at the P4P800/P4C800 series board like Zap recommended.

I'm using a P4P800-VM, but it lacks any control for overclocking using the CT479. I'm only using this because I wanted a mATX computer.

Which board would give the most control for overclocking?

I am using the CT-479 with the Asus P4P800-VM. Running my 1.6ghz dothan @2.4ghz. The board doesn't have overclocking in the BIOS, so I have to use clockgen, but it's been 100% stable at 2.4ghz on stock voltage the entire time I've had it.
