Please help me understand custom core voltage vs Auto
I managed to downvolt my 9900ks to run 5ghz at 1.295v (with turbo LLC on this z390 Aorus Pro)
This is the minimum stable voltage that i feel comfortable with
Under avx load 1.220v
Never goes over 1.3v, however ofc due to LLC, much more 'static' voltage.
The stock, however ran cooler by up to 5°C despite being at 1.38v? And I'd see VR VOUT fluctuate throughout the night (idling). I'm not so sure about the averages on that, but i think they were pretty much the same to what I have now.
I've noticed differences with the liquid temps as well of course, idling at about 2 degrees more which i'd like to go back on but I don't know how.
Is there a way to run this CPU cooler by somehow making it run on lower voltage idle? Cause right now it runs at 1.25v almost at all times and I think that's contrary to what i wanted to accomplish by applying manual voltages (including VCCIO and VCCSA- as they were both at 1.25- 1.275 for like, no reason. They're now both at around 1.150, but that's unrelated really, ofc.) however of course i wanted to undervolt this cpu to increase its lifespan and because Gigabyte and other pro motherboard manufacturers are notorious for putting general auto voltages across ranges of chips that have different efficiencies..
And if there are any upsides to this custom OC, it's that under full gaming load, I've not seen this cpu (package) cross 70°C, which with Auto voltage, i'd see temps up to 80°C in load screens. Game play in all games is generally always 50- 65°C
So do you think i should just put it all back on Auto? I have only just learned to OC properly, on a CPU that comes 'pre-overclocked' and I was getting alright results, but I still don't really get why auto voltage can't scale the idle voltage down as well and instead what I'm getting is more heat out of less voltage in the chip :s lol
Anyway, sorry for my convoluted post right here, I hope you understand the pain and maybe i'm just doing noob mistakes here but I think i've done everything right and I can't find the answers so reaching out to you pros.
Thanks in advance
