Sandbridge on UEFI BIOS Mobo?

[Gordo74]

Any motherboard with UEFI currently does not support Native Power Management in any degree.

Really? Can't see it affecting my computer.

It doesnt if you have NullCPUPowerManagement, but it will not sleep without sleep enabler and it will not speedstep/turbo. Just one speed at one voltage 24/7 with no sleep if no extra kexts are involved. With Gigabyte (which still uses BIOS), native power management (sleep without a kext, speedstep/turbo) all works flawlessly.

Is this still the case?

Motherboard with UEFI BIOS DO require NullCPUPowerManagement. Everything works fine if you don't plan on sleeping your computer (Fine for me, I don't use sleep ever), however, if you will be using sleep, you should look at other motherboards. Other than that, the system works great.
