Oh yeah, what's up! I've got my MAIN machine here running a Athlon XP 2400+ mobile chip running at 2.2GHz on a K7S5A rev 3.1 board. No extra voltage mod, but I can show you if you need a little more juice. 😉 Anyway, this bad boy is running rock stable with 3 hard drives, 1GB of memory, a 6800GT, TV tuner (Hauppauge 250MCE), Promise ATA controller, Creative Live! card (yeah, it's an old ass card), and cold cathode tubes. This thing plays Doom3, HL2 and Far Cry great and like I said, it's solid as a rock! But I'm gonna need to upgrade next year as this thing is about as good as it's gonna get right now. 🙁
Manchurian, you're going to have to look on your board and find the revision number. And like Budman said, get the latest cheepo BIOS, and try your shot at overclocking. Just a word of warning, you're going to have a 99% failure rate at hitting 166MHz FSB or higher, so keep it under 166. But I highly doubt you're going to get anything close to that without a voltage mod with the processor you have. Sorry.
