Just use manual voltage set and see what LLC option fits you best (to get nearest to the voltage you have set)
For me it's Ultra High setting.

My voltage is showing much lower than in the BIOS, and I do have LLC turned on. I'm not sure where else to look.

Not to familiar with GB overclocking as terminology for given bios setting is different than that of the Asus bios which I'm more familiar with however I believe from what I can ascertain from this thread, that you may find helpful, the following settings may be the key to a manual vcore method of overclocking that board to 4.6 with that proc.

 

RATIO CHANGES IN OS [ DISABLED ]
CPU THERMAL MONITOR [ DISABLED ]
NTEL BOOST TECH [ ENABLED ]
MULTI-STEPS LOAD-LINE [ LEVEL 6 ]

 

Please give the thread linked above a full read which I think will help you get where you want to go.

Just a note from my perspective. Theses boards, P67, Z68 & Z77 come choke full of power saving features by default, which is a good thing, and there are many settings in bios relating to these features. Although they can be problematic initially when trying to reach your max overclock, hence the need to disable them, it is always a good idea once you get your system stable to revert back to them for a multitude of reasons. Keeping accurate notes along the way is always a good thing especially the effects of all those setting as it relates to system voltages at idle and under load. The whole goal should be to find what voltages are necessary for stability at a given clock. Once established you will know what droop, for example, is acceptable for your hardware to be stable. When you re-enable the power saving features you will then know what to look for out of those settings which makes reverting back a bit easier. Who needs a full blown 4.8 OC rockin 1.45 vcore 24/7 to browse the internet? short answer... no one. Hence the useful benefits of your proc down clocking to a 16x multi and approx. 1.0 vcore when it's not needed to perform the task at hand. If that means, in the end, you end up with a max 4.6 vs 4.8 overclock to have these benefits you are not loosing that much in terms of overall performance and well worth the trade off IMHO. GL

I believe it's an bug with Gigabyte mobos and CPU-z. I ran another program and the voltage is showing correctly haha redface.gif.

See my post 9948

BTW CPUz incorrectly reports my Vcore as 1.17 (I wish it was -its reporting VCT I think) and have to use Easytune 6 for a Vcore
I guess the only real way is with a voltmeter...
post #9506 of 10697
I am new to OC'ing and I have been trying to find a sweet spot for my voltage offset for a few days now and subsequently need some feedback from the pros.

I have my 2600k @ 4.6GHZ with V offset to -0.65. I ran Prime95 for 12 hours and when I woke up my temperatures were: 51/58/60/55. The max they reached during the night was 65/74/75/71 according to RealTemp.

The key to all this is to keep lowering the V offset until the computer no longer becomes stable, right? Since -0.65 worked, I should try -0.70 and then -0.75 ect until I can get it as low as possible while being stable, right?

OR

Should I stay with my V Offset with what it's at and keep raising the multipler until it becomes unstable? I dont know which direction to go.

Some notes about my rig:

I do not run my rig 24/7. I work all day and come home to a gf and puppy so my computer wont be on until 9ish to about 11ishPM, at which point I am using it for games/web browsing ect no folding. Some nights I am not on it at all. On occasion, it will be on for longer than a few hours like on a Friday night which would be from 9ish to 3am.

Can some one clear up these questions for me, please?

I think you shouldn't go really low offset because the idle voltage can get too low and then it wont able to keep your CPU on when doing nothing. By the way what is your vCore shown in CPU-Z when your CPU is fully under load with that offset value ?

Ok you could lower down your Core Voltage more but you should check your VID (you can see its value in RealTemp when you click on the time since you opened it) and depending of that you should use the - or + sign for setting the desired vCore (there is an explanation for using offset somewhere here on the forum) .. It's also important to see which LLC option works the best for you. Mine is Ultra High which gives me almost exact voltage as I put it in Bios (with minimal vDrop). When you do that you can lower down your vCore with bigger value of offset to get lower temps but you should also use Blend stability test for at least 12hrs which is, as most of people said here, enough for testing if your CPU will crash or not. I did 20 hrs with 1.248v on 4.6 Ghz... Enough for me...

Offset

Once you have 'found' your desired overclock, assuming you have followed the guide above, you should be using manual voltage and the correct level of LLC to determine and eliminate the vdroop as much as possible, then all you do is the following:

Once you know what vcore you require under load, using cpu-z you can work out the offset by using the VID. When running your cpu under load to read vcore, you can do the same to read the VID. That can be achieved by running prime with cpu-z and realtemp. The difference between the load voltage in cpu-z and the VID you see in realtemp is the offset amount you're looking for.

For example if your VID is 1.3875 under load and your cpu-z vcore under load is 1.4275, the offset will be a positive amount from the VID, so it'll be +0.040 (1.3875 + 0.040 = 1.4275)

If the VID is 1.3875 and your cpu-z vcore is lower, say 1.3675, the offset will be a negative value of from the VID, which is -0.020 (1.3875 - 0.020 = 1.3675)

Well, I dont have a static OC. My OC scales back when the computer is at idle. I have never messed with the Vcore, I only used the V Offset to achieve this OC. I mean I understand whats being said, but is it bad that I dont have a static OC and am allowing to scale it back if I go AFK for a hour or two?
