My friend is giving me a AMD 2600+ mobile for free and I plan to replace my 2500+ with it. Currently, I'm able to get 200 X 10.5 (2.1ghz) out of my chip at default voltage with the stock HSF on a Shuttle AN35N. What kind of overclock or speed gains can I expect from this little upgrade, as I am not too familiar with the mobiles (with stock amd 2500+ HSF). Thanks in advance!
