I agree. With the Corsair unit and the Coolit Eco, high end air cooling is dead. It just doesn't know it yet.

Hey I finally got my Phenom II 550 BE to 3.9Ghz running stably , compared to my previous Overclock of 3.8Ghz ... Here is my setup:

FSB x Mult = 205Mhz X 19
VCore = 1.5250V
NBVoltage = 1.2V
Load Temp = 46C
Cooling = Arctic Cooling Freezer Pro 7 Rev. 2

--EDIT--

What a great cpu! I just started working with a 555BE and have been very pleased with the overclock. All four cores unlocked and running at 1.21v at core vid. It was stable at 3400 at this voltage. I bumped up to 1.26v and ran the four cores at 3700 for hours of Prime95, Battlefield 2, SuperPI. Maybe not enough to declare success but very encouraging.

It would run @3800 1.26v but would fall out of Prime95 within an hour. Booted @3900 1.26v but was very unstable (superPI would run some times and not the next; Prime95 lasted a few minutes).

Now trying 3800 @ 1.31v on all four cores. Prime95 is running in the background while I type here. If this is stable, I'll go up again.

Zalman 9700 cooler
Gigabyte MA790X-UD4P
Simple corsair memory @ 800
3800=200fsb*19
Vcore= 1.31v
no other changes from nominal bios

Stable 4 cores at 3800 MHz, 1.28v, C3 stepping, north bridge +0.1v.

I can get 3900MHz with 1.34v and run Prime95 for about an hour, but temps slowly creep up until at about 51c, I get a reboot.

51c is cool as cucumber. Bump your voltage some more. It should stable out.
