QPI/VTT Volt ~ auto
System Agent Voltage ~ auto
DRAM Volt ~ Auto (1.8v)
And I;m going to try it with 4.3 ghz just to stay down a bit. Leaving my vCore on auto, and then adjusting later.

 


Read my post above yours. LLC will should fix you up, try the settings I've provided and report back. tongue.gif

I agree it's probably droop causing instability under load, load CPUZ and see what your voltage is under load as well that could give us a better idea too.

LLC: Level 6
Disable: Real-Time Changes in OS

Give that a whorl for a quick and dirty OC.

Edit - Also watch CPU-Z to make sure that your voltage isn't fluctuating too much. Make sure that it is sitting at the same. (Ignore small voltage changes .01 / .02.) LLC will help your chip stay at a certain voltage under load. Also keep in mind that your voltage won't read 1.315 in Windows because of LLC it will be a tad higher then what you set it at.

On your particular board LLC6 works wonders, was the best number to set it at for me when I had that board and does work very well for others.

Put in what you advised. Here is how it looks so far. Basically, been using Prime95 for a little over an hour, not really doing anything else, gonna run it til I go to bed (would run 24 hrs, but room mate is "sensitve" to light. I try to get him to let me fold through the night but he says "Have you seen that thing?.. if it a f-ing disco ball! And I smile with pride...).

I used to have that board with the 2500k. For some reason gigabyte hasn't released a bios update to enable cpu-z to read out the v- core correctly; if you haven't figured out why your v-core is wrong. thumb.gif

Did you ever notice any boot looping? Mine might be tied to the overclocking failures I have had in the past (I say in the past with hope here, smile.gif ), but I have heard a few of people with the problem.

Also: Looks like I am switching to team OCN for my folding! I posted this same problem over at MPC and didn't get but one response, who basically said the chip wasn't designed for those speeds so I shouldn't expect them... Didn't give me any advice or anything. Since I spend most of my time at OCN, I guess it makes sense to switch!

Edit: After 3 hours of blend test, it still runs and temps are holding. +1 rep!

Also, Any tips where to go from here?

Another Edit: These are the results after running IBT on extreme...

Yes. Boot looping on that board and most Gigabyte boards from the Z68 line-up are or were common.

 

Although glad I could help with your OC, good to see you've got it up and on the road to stability :)

 

If you've got any other questions man just let us know or shoot me a PM and I'll try to help ya out as much as I can. thumb.gif

Would those settings work for a ud4? I thought i had a 4.5 stable oc at 1.35 but well i thought wrong. Right now I'm starting over at 1.39 vcore atm. Sry to highjack you thread just seemed like people here have some experience with giga boards.

No, go ahead. Now that mine runs without crashing, I can begin to whittle down the voltage or up the clock, haven't decided yet.

But yeah, like he said, the LLC is what made mine crash. I never knew whether to leave it off or to crank it up... Just put in what he said, and it should work. Boards are very similiar, so it would most likely work for you too.

Just to make sure LLC is the multi load line for a gigabyte?
