3900X + Asus rog strix x570-f gaming = 1.488 volt cpu

[Zejtan]

Hi folks.

ive been reading around abit ant stumbeld upon the fact that some motherboards overvolts ryzen cpus.

So, i checked. 

Apparently i should have around 1.25 volts for my 3900x.

 And im on 1.488 volts in cpuz.

 

I went into bios and set cpu volt to manual, but it doesnt allow me to manually type in a set voltage ?.

Instead i can set an "offset", in either "-" or "+".

So i tryed that and set - and 0,23125, that what i tought would land me at around 1,24 volts.

quit and save changes. Aaaaaaaand wont reboot. after turning it of/on twice, it went trying to restart and did 3 krasch-restart attempts and started in failsafe mode. 

That i could reboot from and get into bios and put it back to auto and computer restarted. so, here i am. with my "toasty" 1,488 volts. ANy ideas ? suggestions on what to do ?

 

-bios is updated in armoury crate.

-cpu cooler is corsair H150i

-cpu temps are "reasonable", but a tad bit on the high side compared to other 3900x setups.

 

Best Regards from sweden.

p.s spelling errors, grammar and such is what it is.

On single core loads and short bursts its normal. This q has been asked a bunch myself included. On all core loads V will drop to 1.3 range.

hi, this is not the first time this has been reported by users. 

 

actually its been a thing since first gen essentially. 

 

 

tl;dr: its normal low current voltage, once the CPU is put under load, the voltage drops. so does the CPU clocks.

thank you booth.

i did a cinebench R15 run ( 2997 score ) and cpu droped down to 1.24 during test

that voltage offset crashed most likely because you undervolted it too much. Note that sometimes performance just drop with undervolt even though frequency reports is stable and it doesnt crash, this is still a sign of instability.

Mine will do 1.32v all cores in Cinebench R15. Gigabyte board default settings. Cinebench should be around 3250. 2997 is abnormally low.

havent done to many, but my higest that is saved was 3100 points. the one i did with 2997 was just to check the voltage, if it droped. but when you say i should have another 150 points, it makes me wonder

My highest score for default setting is 3279. When it's overclocked to 4.3GHz, the score is 3375.

 

Do you have lots of things running in the background to eat up CPU resources? Or your CPU runs hot for some reason? The boost clock depends on the temperature.

ill have to chekc it abit closer,

shouldnt be anything running in the background and temps as far as i know was decent.

but ill give it ago tomorrow again ill chenc back in here

I only changed my voltage to 1.3 because at that I do not have the CPU fan ramp up and down like I do if I leave it on auto.  That was so annoying

it looks like im doing around 3000 to 3100 with stock settings, havent been tinkering anything specially with overclock on cpu.

but im going to. hopefully i can find some really good "how to" for ryzen.

That is what mine does stock as well.

Will among CPUs have such big variants? I only reduce the vcore by 0.05v in the BIOS. Otherwise, I do nothing to CPU. My 3900X isn't a good overclocker. It needs 1.365v to be stable at 4.3Ghz, So I just run it at default.

so maybe i just didnt get a good ticket in the silicon lottery then =/
