Xtreme X.I.P.
I noticed that about the PWM section too, Dave. On the K9A2 I have, at full load even the heatsink on the MSI would hit above 75C. There is no telling what the MOSFETs were running under it. On the ASUS, even when the PWM section is receiving 166W it wasn't too warm to keep a finger on.
I did some power testing with a Fluke clamp style ammeter.
This is at 2900MHz (200 x 14.5):
vCore, Idle Current, Idle Power, Load Current, Load Power
1.375V 7.0A 84W 11.8A 142W
1.400V 7.3A 87W 12.4A 149W
1.425V 7.7A 92W 13.1A 157W
1.450V 8.2A 98W 13.8A 166W
These numbers represent the power going to the PWM section. On the ASUS board, the AUX12 connector by the PWMs seems to be the sole source of power for the CPU while the ground plane seems shared. As such, these numbers represent the amount of power being used by the CPU in addition to the loss (as heat) in the PWM section. Since the PWMs stay so cool though, I'd say not a whole lot is lost there as heat.
For ACC, I tried -12, -2, 0, 2, 4, 6, 10, and 12. Nothing seemed to actually help anything for me.

Particle's First Rule of Online Technical Discussion:
As a thread about any computer related subject has its length approach infinity, the likelihood and inevitability of a poorly constructed AMD vs. Intel fight also exponentially increases.
Rule 1A:
Likewise, the frequency of a car pseudoanalogy to explain a technical concept increases with thread length. This will make many people chuckle, as computer people are rarely knowledgeable about vehicular mechanics.
Rule 2:
When confronted with a post that is contrary to what a poster likes, believes, or most often wants to be correct, the poster will pick out only minor details that are largely irrelevant in an attempt to shut out the conflicting idea. The core of the post will be left alone since it isn't easy to contradict what the person is actually saying.
Rule 2A:
When a poster cannot properly refute a post they do not like (as described above), the poster will most likely invent fictitious counter-points and/or begin to attack the other's credibility in feeble ways that are dramatic but irrelevant. Do not underestimate this tactic, as in the online world this will sway many observers. Do not forget: Correctness is decided only by what is said last, the most loudly, or with greatest repetition.
Rule 3:
When it comes to computer news, 70% of Internet rumors are outright fabricated, 20% are inaccurate enough to simply be discarded, and about 10% are based in reality. Grains of salt--become familiar with them.
Remember: When debating online, everyone else is ALWAYS wrong if they do not agree with you!
Random Tip o' the Whatever
You just can't win. If your product offers feature A instead of B, people will moan how A is stupid and it didn't offer B. If your product offers B instead of A, they'll likewise complain and rant about how anyone's retarded cousin could figure out A is what the market wants.
