Lower llc (normal/auto) causes vdroop that just keeps going (droops until crash even if i increase vcore). Then if I go up to high/ultra high/extreme I get the SAME results from all 3 but ultra high/extreme are more jolty while high is smooth (all have slight vboost). I have never heard of LLC working the way you describe, I understand your approach though, gives you a little bit of playing room.
@Hellsrage Your LLC seems to be functioning more similar to mine. If you graph your vcore I am sure you will see that on high you probably got a vcore jolt that caused the worker to crash, Where as on ultra high it was more stable through-out. LLC sometimes produces the same results on each setting but will be more jolty if its up to high or occasionally could spike down if just not high enough (even if its just a jolty jump back down to idle vcore it can still cause workers to fail)
That's one reason I didn't even mentioning trying out High and Medium.
They somewhat act a bit differently than Ultra and Regular. The reason why you failed using High and Passed on Ultra with the same voltage settings and values is that, Ultra reacts faster to load than High. As a result, if you can graph it using OCCT as@dmfree88
mentioned, you will see that Ultra has a higher average voltage during Load than High.
Trying out 4.7 is not a bad idea. Just make sure you can cool it down. Also make sure your VRMs get a good cooling. As that would also yield you lower CPU temps. I can get to 4.7 without a problem using the multiplier by using an offset of +0.075 Regular or 1.464 at load.
But note though as I only use AIDA Stress Test not Prime. You'll need more Vcore using PRIME. Am I stable using AIDA? On a daily basis yes. Gaming? yes. Completely stable?
But that is just my preference. @dmfree88
No, it's not that strange. Maybe just the way Gigabyte designed it. Remember the UD3 is not made for the Hexa-FX's. They are meant to be used with 6 cores the most. That's one reason why people can't get better clocks than the UD5s and UD7s using the UD3.
It also has a bad effect Temp-wise since Vcore goes higher than the Voltage at Idle. The more load your system is subjected to, the higher they go, the hotter is your system. It's useful if the Vcore stays at the max during Load. You can just predict it would stay there. But naah!
It jumps back from minimum to maximum at a random behavior. Thus causing you trouble when trying to stabilize.
But I came up with a technique of my own to counter this.
I first set my frequency to my desired value. Adjust the Offset on a given LLC( Regular to start with), Test. If it's unstable, I add a step of an offset, stable? Look at the Temps. Too hot for my taste, I would back off the offset and use Ultra LLC.
For example, If I use +0.100 on Regular, Stable but too hot, I back down to +0.075 at Ultra. (to net me a Vcore that lies between +0.075 and +0.100 on Regular). Test again, If I could pass the stability testing with that setting, I go back to the BIOS and use +0.100 Using Ultra and use that setting as a daily set-up. (Temps while stressing will be much much higher than your daily temps you won't even reach half of what you get on a daily basis).
I have yet to use an app that could stress all 8-cores at once for longer time. So I don't worry about temps after stressing. Edited by mus1mus - 10/16/13 at 5:55pm
