I havent even touched pll voltage with my current clock. pll overvoltage might need to be enabled for the 4.8 that I will probably go for though. Next weekend that I can, its back to overclocking. Must hunt for the magical 4.8 numbers.

My short OCCT and LinX tests passed, but Prime95 failed once it reached the second test on blend, so I've bumped the vcore up +0.005v to see what happens then, this time I will run Prime95 first, then OCCT, then LinX (if I get that far before a BSOD of 0x...124).

There were no stability issues with that voltage on my previous/current 4.5GHz clock that worked fine. I am now trying (as I post this) the same PLL voltage with a drop in vcore by -0.010v, which previously crashed me. Also interestingly I don't know if it's me not noticing this before, but when watching the CPU clock I notice a slight .1-.5 variation every second or so in the MHz, I don't remember seeing that before reducing the PLL voltage considerably.

Anyone here on the thread have any interesting findings to add?
I think the variation you saw is actually normal and I think it happens no matter what. At least it seems normal for me (and my PLL Voltage is still on Auto for now as I am testing other settings that I need to test).

Search for threads made by me to find it, it's on this same category board.
Yeah, but that's socket 1366.

Generally, Internal PLL Overvoltage shouldn't be needed until exceeding about 5GHz. Generally.

good to know. Ill leave it alone unless I am at a last resort for a setting to change and test to see if it makes a difference. Now I need to figure out when I can make a good two day time window for overclocking, with no sleep.....

With no sleep? Why?

Anyway, you're right that it's more of a last-resort type of setting. That's exactly what Juan Jose at ASUS says (he's their Senior Technical Marketing Specialist) .

I watched one newegg video with an overclock guy from asus and that was it. Read a few guides, and many posts here. Overclocking this chip was the easiest I have done. First build was a 775 and then I went to the first i7 (had to up to sandy bridge because psu problems), and I could never really push those too far. They were complicated, but at the same time, I do not think I took the time to overclock as I have my 2600k.

I normally just have trouble sleeping when overclocking. I get so into it, and I hate leaving my computer to test just to see it fail in the morning, so I try to get it stable and leave one day to just sit and watch it test basically.

Well, I've hit a wall with the speed and volts I can go before exceeding reasonably sane temperatures under stress testing. I can't quite get 4.7GHz without increasing vcore, though still below my safety margin of 1.40v unfortunately the temperature increases a bit beyond 75C under stress at that point.

My current settings are something like as follows:
Code:
CPU Settings
----------------------------------------
CPU Multiplier: 46
VCORE.........: 1.365v [OFFSET: +0.025v]
LLC...........: Level 3
DRAM..........: 1.575v
PCH...........: 1.059v [AUTO]
VTT...........: 1.076v
PLL...........: 1.548v
SA............: 0.925v [AUTO]

DDR Settings
----------------------------------------
Clock.........: 1333 [MANUAL, AUTO gives 1066? :S]
Timings.......: 7-7-7-20-1T

GPU Settings (as I currently use Intel HD 3000)
----------------------------------------
GT Voltage....: OFFSET +0.005v
GT Clock......: 1200MHz (Pending further increase and testing)
Any suggestions or does it seem good?
