The end of underclocking and undervolting?

I ran some tests today to get my head around speed/load/power draw. On my HTPC, I have CrystalCPUID running 3 frequencies (1, 2, and 3 GHz) with 3 voltages (.8, 1.1, and 1.275 respectively). http://www.plymptonia.com/pictures/Power_Load_chart.jpg I ran each of the frequencies at idle and load, and w...

The only accurate Brisbane temps I've been able to read are from Everest with it's generic "CPU" sensor, but CPU 1 and CPU 2 are both clearly wonky (-1, 20, etc.. when the CPU is reading 30)

By the way, do you get accurate temperture readings? What are you using to read them? (I've heard Brisbane's don't have accurate temp readings in some/all cases)

I'm currently planning on using 5x, 10x, and 15x (overclocked) for my 3 CrystalCPUID speeds. I'd love it if the black edition went down to 4x, as my HTPC spends about 80-90% of it's time idling. My "G2" Sempron LE-1250 goes down to 4x, but neither of my "G2" X2s did. You'll want to avoid odd multip...

Athlon x2 5400+ Black Edition specs?

Anyone know where to find these? The AMD website is really bad, and I looked through the documentation, and can't find anything related to this chip. ADO5400DSWOF

Specifically, I'm looking for the voltage ranges, min and max multiplier (can it do 4x?), etc.

Anyone? Thanks!

There's no mistaking if C&Q works, CPU temp & frequency shows a big drop at idle. AMD utility is low-level and proprietary so I doubt anything else will work as well.

So 3.0 GHz when I need the performance, 1.6 GHz when not. That's a bummer. I don't think it's a voltage thing - it's either an RMClock bug, or (worse) a BIOS/CPU issue. It's not a supported way to use the CPU, I'm sure, and RMClock is, at best, a great hack. Since I'm using an HTPC, manually switch...
