The +3GHz clocks are easier if the multi is higher and the board/CPU allows it. If my CPU allowed 11.5 multi it would get 266x11.5 and 267x11.5 max CPU-Z because it's the HT that messes everything up, not core speed.
I've worked around it and here are my findings:
I found out the issue is NOT the NB or CPU speed BUT the HT ref. speed.
The maximum for everyone I've seen is around 250-268 HT ref. Mine is 267MHz HT. ref.
Here I threw ALL speed including CPU/NB/HT to VERY low and only left HT ref. speed high. HT in total ran at 1x.
The HT ref. I tried with no volts added and max volts added. In both cases it goes to a maximum of 267MHz and then freezes the system. Here was 261HT, 265HT, 266HT and then 268HT up from 266HT when it froze.

I can boot 255HT ref. now stock volts, all cores.
All this looks like a CPU limit of HT ref. If anyone gets a chip that does 270MHz HT ref. all cores, they should be able to get +3GHz easy. We need to find out how to unlock higher multipliers...
267x13.5 looks especially good.
AC. DC which is actual power consumption is lower, multiply by 0.83.
2.2GHz stock all volts, low HT gives ~177VAC max.
2.64GHz stock all volts, low HT gives ~200W VAC max.
2.7GHz max all volts, high HT, high NB gives ~330WVAC max.
NB needs those volts to achieve high speeds, yup.You only had to change the Nb voltage +0,1V to archive those high NB and HT frequencies so i assume a similar power consumption.
I think around 2.60GHz is most efficient.This system runs more power efficient (GHz vise) if overclocked to 2,6GHz.
What HT and NB total speed (not the reference clocks)? That'll make a major difference. Let me know that I'll try it and let you know.As my 9500 still did not arrive and the M3A seems to be delayed till 12/12 may i ask for CnQ enabled (or lowest possible multis set) idle power consumtion at 200 vs 240 MHz HT?
I've done my own measurements. Mine idles around ~25W and load is around ~50W max using ATi Tool.HD 2600 XT's power consumption here in idle ~30W.
I'll measure power draw at stock with all stock volts again and let you know what the DC W value is.So using an HD 2400 XT or pro instead should substract ~20W from the power usage resulting in 80W consumption for the whole system w/o CnQ.
