How high do you think I can push this 550 with a lapped Arctic Cooling Freezer 64 Pro?
I had my 3600 Brisbane at 3.1Ghz full load 47c
Well I had my 550BE 0919EPMW at 3.8GHz (200x19) at 1.4V, the load temps when running prime were around 45'C. That was using the same HSF as yours (lapped also) but my case has 4 120mm 60CFM fans which shift a fair bit of air.

What I found with my chip is:

200x18 @1.3V (stock volts) = ok.
200x18.5 @ 1.35V = ok.
200x19 @1.4V = ok.

So I needed 0.5V more per 100MHz step after 3.6GHz. (This was with all other voltages at stock, NB, CPU-NB, etc)

Good luck, hope your CPU unlocks to 4 cores and is a good clocker
