Cool and Quiet with new higher overclocking (continued)
The AMD processor driver (amdk8.sys 1.1.0.18) was installed.
http://www.amd.com/us-en/Processors/TechnicalResources/0,,30_182_871_9706,00.html
Before this the system was running the native Windows XP processor driver (07/2002).
The version of the processor driver installed in a system can be found in the Windows device manager.

Updated DFI LP UT NF4 Ultra-D to Bios 414-3 (for TCCD).
Major improvement:
- Dual channel memory modules can post without error and operate in DIMM 1 and 3 (yellow). Previous bios 310 and earlier posted with error when modules are in DIMM 2 and 4 (orange) (hitting F1 can bypass error and boot). I think bios 316 or after fixed that.
- Cool and Quiet (CnQ) can now operate stably up to the same high frequencies of CPU, HTT and memory attained when CnQ was not enabled.
- CnQ HTT and memory were improved from 293 to 317 MHz (at least), CnQ CPU from 2.64 GHz to 2.85 GHz (at least)
Tested:
HTT to 317 MHz
CPU to 317 MHz x 9 = 2.85 GHz
memory to 317 MHz 2.5-4-4-7 1T
Have not tested between 317 - 328 MHz (or 2.85 GHz and 2.95 GHz CPU) which is semi-stable without CnQ.

Between idle/light load to full load,
voltage swing (from 1.1 V to 1.40 V) * 1.10 = 1.40 / 1.1 = 1.27
frequency swing (HTT x 5 to HTT x 9) = 9 / 5 = 1.8
current swing between idle and full load = (1.40 / 1.1) * (9 / 5) = 2.29
CPU VDD is switching between 1.2 V to 1.54 V, CPU frequency from 317x5 to 317x9 MHz, a difference of 80%.
Idle/light load CPU and system temperature drop about 5 C as VDD is decreased by about 0.34 V using CnQ.
