They scale pretty good up to 3.6, but from there most need a lot of voltage and put out a ton of heat. Even if you are lucky enough to get above 3.6 with low voltage, it's still hard to keep the temps reasonable with air cooling. Once summer hits and my ambient goes up to 80-85f, I'll have to clock it down.

Here are my voltages:

Cpu Voltage = 1.4
Cpu Voltage Reference =Auto
Cpu Voltage Damper = Enabled
Cpu PLL Voltage = 1.5
Dram Voltage = 1.95
FSB Term Voltage = 1.3
N.B. Voltage = 1.4
N.B. Voltage Reference = Auto
S.B. Voltage Reference = Auto
4x4 is making one of the most honest statement that I've read in some time. You need to use brute force or water cooling to get much above 3.6Ghz. I will go one step further and say that every "GO" stepped chip with good air cooling should reach 3.6Ghz or you've failed miserably. FrostyTech.com reviews all the good coolers.

If you look at all the water cooled systems with 3.8Ghz+ they usually have a Vcore of 1.55v-1.7v. They use brute force to break the 4Ghz barrier.

For the air coolers, (like me) we have to wait for the 45nm quads to break the 4Ghz barrier for a 24x7 stable computer.
