On a side note, I was given a bios at Quake Con in attempt to fix an issue I had, turned out to be something totally different causing the issue. Anyway, I was told it would probably be labeled Bios 1000, but it looks a lot like 0009. I was told it had improved memory performance. I will try and get some pics up later this week of the bios settings, but as I stated already, it looks a lot like 0009.
funny that dropping the PLL helps so much, what probs did you have with it before? I've found that turning the LLC to 50% is the key (for me). I don't like having it on 100% because then it seems to overvolt under load. on 0% mines vdroops over 0.05V, it is much more stable with it on 50%.

bizarrely it seems that it can run with lower load voltages at 50% LLC than it can with 0% LLC. eg it is stable at 4.0 at 1.27 under load with 0% LLC (1.325 in BIOS), but unstable at 4.13, even at load 1.296 (1.35 in BIOS). But with 50% LLC it seems to be stable at 4.13 with 1.27 under load (1.30 in BIOS).
