6 months ago I would have scoffed at anyone talking about 'burning in' a CPU and getting better performance.. Can't give you a good reason, just did not seem sound to me..
Now, I feel different.. I have a 366 (SL36C week 28) that I bought pre-tested to do 550 at 2.2v..
It was real stable at 2.2 but I experimented with lower voltages to no avail..
This is with pretty normal heat sink and Globalwin CPM Fan... Also, even at
2.2v I could not get stability at a higher FSB, i.e.. 103 for 567...
Now after several weeks, nothing else changed, I tried 2.1v... Rock solid..
Bumped it up to 103, still stable as can be.. So, unless I'm overlooking some other
variable, ( I have not knowingly changed anything else) looks like there could
be something to 'burning in' after all..
