thats suck :/ u need to have luck for get better clocks. whats making 2 cpu different than each other? silicon quality only?

2 cpu's produced next to each other can clock very differently. Microscopic differences and impuritys make them all unique.

But there is still some merit to the batch hunting, some batches produce a higher number of good chips compared to others.

So bying one chip from the net without even knowing batch is pure luck. Checking batches in forums etc might improve your chances by som percent.

Bying more than one chip increases your chance for a good one even further.

Asus tested 100 2600K, and without "Internal pll overvoltage" they found this:

1. Approximately 50% of CPUs can go up to 4.4~4.5 GHz

2. Approximately 40% of CPUs can go up to 4.6~4.7 GHz

3. Approximately 10% of CPUs can go up to 4.8~5 GHz (50+ multipliers are about 2% of this group)

So if you buy 50 2600K, one of them should do 50+ mp.

With "internal pll overvoltage" enabled in bios you should add 3-5 more mp and that is the odds.

Later batches might push the percentages in either direction from what Asus found, and that is why we are all hunting
