Specs:Gigabyte Aorus Gaming 5
9900KF
16gb 2666

Overclock is Dynamic
Vcore LC High
AC Loadline 1
DC Loadline 1

Straight to the fix, is there a way to set a minimum vcore whilst also setting a max Dynamic vcore?

My problem is I'm stable at 1.2v & lower during Prime 95 Small FFT's @4.8ghz for my day to day overclock whilst allowing vcore & mhz to drop according to usage. My issue is when at idle or during light loads like Youtube I get randoms BSOD. Recon its a low volts crash.

Secondly I tried to set AC/DC Loadline back to 0 but noticed my VID core would hit over 1.5v. If memory serves me right you can ignore VID core when using static and just use vcore readings but when running Dynamic VID is an issue and has to be monitored as it can fry your chip. Am I right or wrong on this?

Any suggestions would be greatly appreciated. As you know the 9900k's are a hot beast needing taming if you want to overclock and stop you PC catching fire!

P.s Is Prime95 a valid test these days on 9900k or are we better of using Cinebench R20 for instance?

Thank you

You need to use a higher llc and a lower dvid,that way itll idle with slightly higher volts as far as I remember

Or the other way round,check in cpuz to see,higher dvid and lower llc,or higher llc and lower dvid

When you say LLC is that Vcore LC on Gigabyte or is that the AC/DC calibrations?

So I would tinker with AC or DC by upping it to or downing it to lower dvid whilst upping my idle voltage?

Thank you
 
Ahhh I think I have said all this wrong. I'm talking about idle and (VR Control) IA AC: 1 / DC: 1 Loadline.

I understand that I have to use IA AC/DC 1. So to clarify, Vcore LC High, VR Control IA AC/DC set to 1. Dynamic for my now 4.9ghz is +0.010 for 1.24v. Its stable now as increasing the voltage for 4.9ghz increased my idle voltage.

So is there a way to keep the above settings but just increase idle voltage? Can I do this through VR Control IA AC/DC?

If I'm understanding you right the best way is to just change the Vcore llc from high to say turbo and then adjust Dynamic vcore accordingly etc..? Or can this be done through cpu internal AC/DC Loadline or leave that alone?

Thanks again Wazz for your help.

Tbh im not sure on those chips,I know on z77/3770k you just adjusted dynamic vcore and vcore llc

You'd have to test ac,dc to see
