    (Retro!) Best Pentium M for overclocking

    Hi folks! I got a good deal on Ebay for a CT-479 to go with the P4C800-E Deluxe I found in a dumpster(!) and I'm wondering which CPU to get. Dothan, of course- and I'm looking for highest performance, not necessarily highest OC %. As such, it looks like my options are either starting with a 2Ghz/400fsb or 2.13Ghz/533fsb chip (there's a HUGE price difference between 755->765 and 770->780). Looks like 2.6Ghz won't be a problem and I'd really like to try for 2.8+. Thoughts?

    Sorry thread necro but I was literally going to do this soon as well.

    I was looking at getting the 780s as they're pretty cheap on fleabay atm.

    Just an FYI from my experience dothans have hard max frequency walls, which increasing voltage does very little to. In a laptop I did a PLL mod to get one to 2.4GHz. It could boot at default voltage, but it was unstable. To get it fully stable I had to add .112V IIRC. That's a lot of voltage just to get something from bootable to stable.

    They don't oc a lot...but they had great performance back then, compared to desktop chips using older architecture.

    What was weird was that people were hitting almost the same clocks in laptops as in desktops. The best people could do in laptops was 2.66GHz while people overclocking dothans in desktops only got around 2.8GHz on air.
