My son and I did this with one of his systems. We spent about 6 hours on the first processor and 2 on the second making the modifications (it really helped to know what we were doing). So far, his system has been stable at 375MHz but not at 450MHz. > > That's the hard way. For the easier way, see the various dual > celeron articles at: > > http://www.cpu-central.com/ Our preference would have been to do it the easier way (with the MSI converter boards), but he was unable to locate any within the timeframe that we would have needed them so we modified the slot 1 processor boards. I've also heard that there are converter boards available with jumpers to effect the change, though I've never seen them or anyplace claiming to have them so they may not exist. Doing the mods to the processor boards wasn't too bad but it is fairly tedious and requires pretty good soldering skills. Also, had I not had a stereo microscope I doubt that I would have been successful (the wires and land patterns on the boards are pretty small).
