Do you know how what causes the voltage to go above the value set in manual?

I thought it was the LLC but a lvl 1 or lvl 8 i get the same resulting vcore.

I set 1.25v manual, get 1.264 on all cores on load, and one core spikes at 1.280

There is the VID, that´s the value you set in the Bios labeld as Vcore
And there is Vcore, the readings you get from the sensors in Windows

But the chip is not applying that setting 100% correct. So there is a difference, that can very a bit, for me it is 0.02volt.

That´s the reason why the Vcore in your program is different from the VID.

So although I´m setting for example 1.25v in the bios my chip actually uses 1.27v.

The Vcore in your program, from the sensors, is the correct amount.

If you´re using the right version of the program.
What are you using?

I hope that was understandable.

Do you use HWM Monitor, there is in the first part under your motherboard the Vcore, and i the second under your chip the VID.

What are the readings there?

It's normal for the chip to run about 0.02V more than what you set under load, they pretty much all do that.

LLC acts on VCCIN, not Vcore.

im running my i5-4670k at 4.5 ghz with h100i cooler and 1.340v. Max temp on stress test after 50 minutes was 82, it goes from 79 to 81 all the time and occasionaly rews up to 82. Next day im going to try 4.6 with 1,360v its not delided

Trying to get 4.5 stable but no matter what I do it still shuts down randomly at least once a week and says previous overclocking settings have failed.

ocing by yourself is hard work mate, ive spent literaly 11 hours trying to make my i5 stable at 4,5 ghz and finally succeed.

Update on my score: i got the beta ver of corsair link and now my fans are finally working properly altough they got loud as hell on full load but thanks to this beta drivers i made my temps tamed down abit and they dont kick up more than 77 degrees now (thats roughly 5C difference) \o/

All of a sudden my usb devices go crazy and after a restart a high pitched squealing noise comes from my rig, this is when I have overclocking settings applied, when set back to default everything appears to run normally for now. Is something set wrong in my mobo?

yep it's probably mobo sided problem. From my own experience i can tell you that msi mobos suck, had them before and was never happy. Even if they cum on them and on their military class stuff, they are just crap. Ive got myself gigabyte mobo and works flawless tbh so far no flaws with it. After 3 months of use msi bricked twice (threw it away after 2nd one) now it's 4th month of using gigabyte NO PROBLEMS AT ALL smile.gif Change mobo and try to oc once again, probably the voltage you been setting on ur cpu was too much for mobo to handle and now some **** occurs.

Yeah this msi 780 ti gaming edition is also not overclocking very well, and the fans rattle when at high rpm. I should have gone with the evga classified and an ASUS mobo.

I would really like to know what would be an optimal bios config for the MSI GD65, voltage aside.
