Thank you Doctor, and thank you Larry. Doctor let me know about Larry making the voltage mod. I bought one and set it loose on a friend's system. The kit looks nicely done, all heatshrinked. First we tried grounding it against the CDROM, but even after turning it quite a few times, nothing happened. So I yanked it out and checked it with my multimeter. Damn, it took a lot of turns... guess that's better for safety. Anyways, put it back in his system, but this time grounding it out against a motherboard mount. Probably didn't make a difference... anyways had to turn the screw about 20 times, but then the voltage started rising!!! It goes up pretty gradually, making it easy to fine tune. We set the default to around 2.00 and was able to clock his Athlon XP 1600+ to around 2100+ speeds with +.025v. His CPU is still locked, so we're running it at the maximum FSB of 166MHz. Now he just needs a better HSF than a Volcano 7.
Hey, question for all of you "in the know." Does this voltage mod work on all motherboards using the HIP6301 chip? I think my MSI 645 Pro motherboard has one of these chips. If so, then I can snag another kit (if Larry makes more) and push my P4 1.6A some more. I already have done the wire trick on it, and think I still need more vcore.
