Well I got my athlon XP 2500+ 333 to operate stably at about 2040mhz and below 50C after 6 hours of prime 95 and another 6 of seti@home. I used a 12 x 170fsb setup - stock vcore.
I actually got it to run stable at much higher speeds, but aside from pusing temps up to 52 under load, It also involved heavily overclocking the ram. Since my ram is one of a few things I don't have under waranty right now, and I don't have any cooling (even passive) for it, I chickened out and brought the FSB waaaay back. Seeing my ram up over 300 when it's rated 266 had me nervous, OK
anyone who has OC tips for this setup, let me know
