Someone please tell me what is going on.

Okay, Z77 Extreme 4 POS motherboard. Bios is set to Load level 1 (the one where the Vcore stays level through all levels of processor utilization), per core ratio is all set to 40, bclk is 100 and vcore is 1.200V on FIXED MODE!

okay, looking in AXTU and CPUz the Vcore on 100% load is reaching 1.384V on 8 phase and it is bouncing between 8 phase and 4 phase (1.208V on 4 phase).

Pulled the GPU to see if my issues with overclocking was power related due to the high draw GPU, but I am still having issues. A 600 watt with 42 amps should be able to stabily run a i7, 2 HDD, 2 DDR3, and a DVD drive, yes? Heck, a feaking 400 watt should be able to. So this leads to one of 2 issues in my mind. Either a screwy PSU that don't deliver steady power, or the motherboard is screwy which I still do believe.

If it is the motherboard, then why the heck can it not steadily provide the power that the BIOS is telling it to rather than jumping around. it makes little sense to me at all.

And just a FYI on what else it is doing, I have it set to run 30 passes of burn test and it is on run 15, its been 2 hour 9 minute on that. Issues did not start until about run 12. It ran 1.200V 4 phase until then.
 
Do you have LLC enabled? If you have vdroop it will help to compensate for it. Alot of times it will over compensate though. Which is what it looks like its doing. Some boards have a disable setting, but some dont really disable it, but just makes it in a kinda of a low level auto setting.
 
in it hat case it is set to level one. It is not a on of, but a how much in my BIOS.

and your image is funny.

On that one I have no idea if its Level 1 is the lowest or highest. Its job is to compensate on CPU voltage under load.
 
If its on Level 1, I would try like Level 3 and under load see if the difference get smaller or larger in voltage. If it gets a larger increase, then I guess your stuck with Level 1 being the smallest. You would think they would give you a disable option.

Thats a problem on alot of boards with LLC, they over compensate the CPU vdroop and run your CPU voltage higher then you wish.

on level 3 it is running below the set volts. Got a screen to show it. So on level 3 if I overvolt to get the stable 1.200V it will be far too high on low load events. :(

I have my LLC on auto. Clocked to 4.5ghz. with 1.360V set manually, it will under load flog between 1.360 and 1.375.
 
Well when I get to 1.300V it starts hitting the 80s on most cores. The hot core hits it at about 1.250V. And to me, as far as I have been told, that is too hot on these chips. :(

And ill try it at auto and set it to 1.150V and see if it will run.
 
Eh, left it at 1.200V and set LCC to auto. Its running right now on burn test, but the vCore is 1.120V, so expecting a BSOD at any moment. I'm gunna let it run though. Might be something that is freaky and be stable lower with it on auto. Never know. GTX 480 is back in though.
 
Yeah, 80s is alittle on the hot side.

I would just keep trying different levels and see which one kept the voltage closer to your manual setting under load.

yep.
Its running upper 50s and mid 60s on the hot core with it on auto currently. Waiting for burn test to finish, then a day of prime and it will be fine. Or would 200 burn test runs be fine? takes 5 minutes to run 1 pass, so 1000 minutes to run 200 thats 16 hours. That would be a solid test of stability, yes?
 
Okay, it looks like the stock settings offset is .09 volts more or less. I know 4GHz is sort of stable at 1.200V, so I have it set to 1.300V and running 30 runs now. Temps seems to be good, low 60s on 3 cores and upper 60s on the hot core. Should be good now. If it can finish all 30 runs, then Ill start a 24 hour run of prime to make sure its stable. Then try 4.3 again to see how that runs. Hoping to get 4.5 if possible. Knowing the offset should help, and it will just be volt adjusting now.
 
Okay, Ran like 15 or so passes of burn test and 4.5 hours of prime 95 with the setting on stock and vCore of 1.300V (running 1.208 under load), and it is stable. I will test more tomorrow when I don't have anything to do on the computer.
 
So your saying its dropping from 1.30V to 1.208V under load. Thats at 4.5ghz.? If so and stable thats pretty good. If you have any problems, like said you could try the different levels in LLC to see which one keeps it closer to what ever you have the voltage set to manually, which I guess from your post is 1.30V.
 
Yes, its dropping from 1.300V to 1.208V, which is fine. I set it up .100V originally because I knew what was stable. And I am not running 4.5GHz. On this chip on this board that was running at 1.450V which had temps in the lower 90s, which is boil your water and fry your egg temps, especially with the space heater of a graphics card that is in there. I am running 40*100 currently. I will try to run 43 later, as I liked that speed, but I will have to write down my settings from current to be able to get it back to normal if I can't stabilize it at 43.
