Hmm, is that so? I guess I will raise it up a notch or two and leave it running overnight. You know what, I will probably end up backing down to 4.0GHz or so to ensure maximum longevity...

Edit: Quick question guys. When I was in the bios earlier, I noticed a setting named "Internal PLL Override". I google'd it and could not find a lot of information about it. By default its set to disabled. Should I leave it as it or enable it?

Thanks.

Well, my chip required 1.36v for 4.8GHz when I first got it. I could do 5.0GHz on 1.40v. Now, it takes 1.425v for 4.8GHz, and temps get too high to reach 5.0GHz now (needs 1.47-1.50v or so now). Others have reported the same as well. They claimed it was "degrading". But I honestly think its just a burn in type thing. Because I've been rock stable with the higher voltages now that its set in there.

PLL Overvolt / Override should be disabled for under a 48x multiplier. It can cause a cold boot issue, where your machine doesn't want to turn on from a cold start. Since this is your neighbor's machine, and maximum long term safety is at stake here, I'd leave it off.
