Thanks for the feedback on OCing my k6-2 500, I've come to the conclusion that it's pretty much a lost cause. Now I have another question, any ideas on why I can't run it at the default voltage settings with any hint of stability? At 2.2v I get random BSOD and any higher I get registry errors repeatedly (and it doesn't even get very warm). Right now, I'm running it at 2.1v and it seems stable. I thought these things were supposed to be able to run at 2.6v with no problems.
