I'm currently engaged in tuning an A6-3500 Llano APU (2.1 ghz/2.4 turbo) for HTPC use via network streaming. I would like it to run as quietly as possible so I'm underclocking/undervolting it.
The thing is, when I drop the multiplier back to x17 (at 100 bus speed for 1.7 ghz) the CPU speed stays maxed at 1700 at all times, even when the system is idle. The outcome is that my temps aren't nearly as cool as I'd like. When it's at its default speed the CPU speed drops back to 700 mhz when idling (or sometimes 1400).
Is this a feature or a bug? Or am I doing something wrong?
