I've never heard of LLC before yesterday, I don't know its function or how to change it, could you go through it please?

Really useful to refer to your motherboard manual for instances like this. The descriptions are sometimes vague but at least familiarize yourself where stuff like LLC are based in bios. Probably read mine 4 times over lol.

My LLC is set to HIGH. I imagine this is equivalent to the ASUS board but drop it one level like wazza suggested and see what cpuz reports. Ive used LLC as a rough baseline to determine how much volts my OC needs at a certain frequency but theres still NO substitute for setting and testing specific amounts.

My guess is that you might not reach [email protected]. May need more, possibly less. Each chip is different and require slightly different values.

for me to be stable at 5ghz it takes 1.48vcore but i cab that got Intel OC warranty plan

You want to have some proper fun get that and just go all out on it ^^
Guess i have not won chip lottery on cpu

How does offset mode work exactly? When I turn on offset mode I can't choose which voltage to put it at, so how do I know where it's set?

Zeed · 28 Feb 2013 at 16:52

it uses factory cpu presets more or less. Chip knows at what mhz how many volts it should need. You can add extra on top of that.

My offset is set at +0.20 right now. What effect does this actually have?

wazza300 · 28 Feb 2013 at 17:20

it adds +0.0200v ontop of the cpu's default voltage,llc will add some more aswell

The use of offsets are useful for energy saving. If you really want to push your chip, its recommended to disable features like:

C1E
C3/C6 STATES
Thermal Monitor
EIST aka SPeedstep (seems to be different opinions on this one)

Doing so disables use of offset afaik, leaving you to rely on vcore and LLC.
Which method you use is up to you. Offset seems like a good way to prolong life of chip.

I'm back. I've ran 5 runs with a Medium LLC and +0.20 offset.

You may notice the temps are the same, however, throughout the test there was a broader spectrum of temps. They went from as low as 68c to as high as 77c. The average was about 73-4c across all cores. However, this was at 100% obviously, and I can't think of an instance when I've ever ran a CPU up to 100% usage. What do you think I should do? To me it looks like a stable 4.5GHz OC but given that I'm not experienced in it I'm very aware that I could be wrong and would like some input

wazza.. you using sabertooth z77? if so what bios version is that??

Mine doesn't look identical, although it has all the same parts. I've not got around to downloading and installing the latest one on the board yet. Is there something in those pics you need help with?

nahh im using a z68 v pro,they are all similar though same as gigabyte boards

pretty much universal in the way they overclock

@the op have you tested with lower vcore? +0.015v or +0.010v for example

yeah looks identical to sabertooth bios, was like wtf

i dont have some of those options

If your happy with the OC, you could set a longer stress test (3-6hrs). Even then best thing to do is just use your pc as normal over next few days and see what happens. Typically stuff like gaming, folding at home and encoding will stress cores close to their max and potentially reveal instabilities where programs like prime or even ibt couldnt uncover.

Your temps are decent for that OC but they can be reduced further if your able to use a lower offset. I dont use offsets myself so best listen to wazza on this.

If you really interested, next step would be to try reducing PLL voltages but i dont have enough experience with that yet as im still tweaking my own system.

heres why i use offset

idle

load

it clocks up and down depending on load

I've noticed my voltage often sitting around 1.02-1.13v. I think I'll keep that as it is. I don't know if it's worth pushing for 4.6 with current temps under stress. What are your thoughts?
