Getting a few more mhzs

To get a few more out of your northbridge,lap down with 400 grit paper then a final lap with 600 grit....... this gets you a few more. A good heasink with a high speed fan say over 4000 rpm with get you 2-3 mhz while a good lapping will get you another 3 mhz. Its just that lille bit more if your at top end......... The higher the fan rpm the more mzhs increase.
Cheers............ for those of us who just need alittle more.............
