For the test run that accompanied the pictures here were the settings:
CPU Voltage: BIOS:1.35v Real: 1.344v
CPU GTL Voltage Reference (??): BIOS: AUTO
CPU GTL Voltage Reference (??): BIOS: AUTO
CPU PLL Voltage: BIOS: AUTO BIOS Hardware Monitor:1.648v
FSB Termination Voltage: BIOS: 1.34v Real:1.28 to 1.30
DRAM Voltage: BIOS: 2.1v Real: 2.14 to 2.16
NB Voltage: BIOS: 1.34v Real: 1.52 to 1.55
NB GTL Reference: BIOS: AUTO Real: ??
SBridge Voltage: BIOS: AUTO Real: 1.07
PCIE SATA Voltage: BIOS: ?? (I will assume AUTO)
All "Real" quoted are under prime95 load. I saw ranges of voltages in some cases during the 24hr test.
The pattern I used to find stability was to raise the vNB as high as was safe and my cooling allowed, then step by step upped my Vcore voltage until 24hr prime95 passed. Then I went back and low balled the vNB step by step upping it until the sweet spot was found for 24hr stable.
I did that for 3.6GHz and now trying to finish 3.7Ghz. One other thing is I would have never reach a stable "safe" 3.7Ghz without the Pencil Vdroop mod. My Vcore would have been way too high, I know because I tried before applying that mod. Here is the link, it is only for some ASUS boards: Pencil Vdroop Mod - (I used a 3B pencil) http://forums.techpowerup.com/showthread.php?t=60341
You have to have allot of patience as I have had prime95 failures after 7, 12, 13 and even 20.5 hours. The 20+ almost killed me but I want to stick to the plan.
Assuming my latest stability test passes the 24hr mark the only "unsafe" for 24/7 voltage in my opinion is my vPLL (1.648) which is +0.048 over the guidelines I captured from this thread and some others.
I have queried on this thread for some advise but so far have not received any replies.
