I've installed Server 2008 R2 Sp1 on a Gigabyte 990FXA-UD3 with an FX-8120 and the CPU sits at 98% maximum frequency 100% of the time instead of downclocking as expected (and observed) as it does Win7 Pro. If I manually set the "maximum processor state" in power options to something lower like 50%, the CPU will clock down to that defined maximum and sit there.
Has anyone experienced this type of thing before? Any ideas how to get the system to downclock when there is no load?
As an aside, I did install the scheduler patches for Bulldozer before I noticed this issue. Not sure if it's related at all, though.
*I think this may have something to do with the Hyper-V role. However, my other Hyper-V box is on a Phenom II X6 1045T and power management seems to functioning without issue. The host's CPU frequency is dropping all the way to 28% when load is very low.
