I tried 1.55v cpu PLL for like 10 minutes of prime95 blend, seemed alright but I went back up to 1.6v cause like you said, anything under that is red... worries me =)
I don't think CPU PLL undervolting affects temps for me but I am currently testing 1.43v (-0.02v lower than my 24/7 OC) combined with CPU PLL 1.6v.
I think my choice for this testing tonight will consist of:
-2 to 3 hours of Black Ops
-8 hours of prime95 blend test overnight
Why? Back in January I had a 4 hour Prime95 blend stable OC crash in Black Ops, needed more vcore, surprisingly! =D
 Black Ops played just fine about an hour and a half at lowered voltage, but that's no indication of stability, it's currently Prime95 Blend testing overnight, I wish you all luck with your testing.
I'd like to thank everyone that made this BIOS possible as a few suggestions/bug fixes in this topic were included in F308 (command rate bug fixed, C0 power state limit is now default, lower CPU PLL available).

What's the purpose of dual 8pin power connectors? Also, for example my PSU has a 4+4 and an 8pin connector, can I use both without problems or must I use some adapter?
You only need to use one of the 8 pin connectors, plug in your 4+4 into one
of them. Any one. Both 8 pin cpu power connectors are only for extreme overclocking, I run a rock solid OC using just one of the 8 pins.Edited by Scorpion667 - 3/9/11 at 12:39am
