newbie overclock question

[Salacious B Crum]

I have the ASUS Crosshair hero VI I have a very stable overclock at 3.95 when I have the voltage set to auto I noticed that it idles at 1.43 and when I load it in aida64 it drops to 1.39 stable so I figured I would manually set the voltage to 1.39 did that and in aida64 it drops to 1.34 - 1.35 I think I've read somewhere that there is a setting to maintain voltage or at least idle at a lower voltage it just seems backwards in my case any help would be appreciated.

 

On another note I reported that aida64 and corsair link were reporting accurate temps against Ryzen Master and it still does but I have noticed that somewhere along the way while using my PC that changes back to the 20C offset when I reboot it again they report correctly anyone else seeing this?

 

Edit: R7 1800x

he got a 1800x

be sure to include that in the thread next time @mrbilky

The drop in voltage is owed to insufficient LLC (Load Line Calibration) during high current draw/load. What LLC does, depending on the setting, is make your board pump additional voltage through according to CPU load. There's always a small drop in voltage when the CPU is under heavy load, and that's what you're seeing. To overcome that, you find the LLC setting in your BIOS and increase it accordingly. The best I can recommend is looking up tutorials from reputable sources pertaining to your board/CPU combo. Usually they will hint at LLC settings and the like you should use for a certain overclock.

 

Insufficient LLC can lead to instability under load obviously, so it's best to increase it the more aggressive the overclock (due to the increased current draw). Bear in mind though, you have to be a bit frugal with that setting, as being overzealous can lead to some massive momentary spikes in voltage, especially during stress tests.

TY! That did it totally stable at idle and load no spikes after an hour of aida64 thanks again!

Any time!
