I sorta did, each CPU is different even if they are the same make/model.
But my advice is to buy a new cpu. GO EBAY!!!
You all need to start taking some risks. My 3800+ 2.0 ghz stock is now lapped and running at 2.4Ghz daily and ist been going for over a year on the stock fan.
Lapping is one of the ebst things you can do to your CPU to lower temps.
