Ryzen getting high cpu voltage

[Adarsh Singh]

Ryzen CPU receives high voltage (1.45+V) even when idle with Ryzen balanced power plan.

is this okay?

ive tried using balanced powerplan and it helps to lower the voltage(0.8V) on idle.

what should i do?

I wouldn't trust it on auto voltage at all, I tested mine to see and it went up to 1.5v on idle and non OC'ed only @3Ghz. Dial in a fixed voltage for sure, what have you dialled in for frequency?

My motherboard's default voltage was an offset equaling 1.375v for stock with the 1600X.

 

I was able to bring that all the way down to 1.28v for stock and 1.331v for a 4.0 GHz overclock.

Yeah, my 1700 I have clocked at 3.7Ghz @1.2? Volts, nice and stable... I did have it at 3.8/3.9/4.0 Ghz, but stability issues, and only running stock cooler so decided to ramp it down a bit to 3.7Ghz.

I could drag my village down till 0.66V with Ryzen master. But hwmonitor was showing the same 1.35 v. Which one should I trust?

 

Yes I clicked apply on the top of Ryzen master

I honestly don't know which readings are most accurate. I've heard the latest version of CPU-Z works well for voltage readings.

The Ryzen chips don't get damaged from the voltage they are designed to be able to operate at a higher voltage than most CPU's, but yeah you should dial it down a bit

Since I have to do 1.28v for stock and not that much higher for OC (1.331v), I'm wondering if the load line calibration on my Asus Prime B350 Plus is a little funky considering you've got an eight-core working at less voltage.

 

Or it could just be XFR being weird with voltages since it ramps up two cores to 4.1 GHz? I know XFR is working because I see it happening all the time in Ryzen Master. Since that's a really high frequency with Ryzen, that probably ups the voltage requirements a bit for stock.

R7 1700 and on stocl settings I get 1,417V at idle and 1,2V at load.

So if that's stock, I won't even worry about it.

Yeah, more likely to be XFR I think, but every chip is different too, so could just be silicon lottery at work too. Not much difference if you think about it though, your 1600x had a base frequency of 3.6 and boosts to 4.0, whereas mine is base 3.0 and OC'ed to 3.7Ghz, so don't think that 0.05v is bad at all really. It would depend on your usage of course, but might be better to turn off XFR and apply an OC across all the cores instead. Make sure you save a profile of your current settings though just in case you decide you were better off how you are now.

 

OP, might be better to dial the settings into the BIOS directly than through ryzen master. It also only tells you in there (ryzen master) what you have set, not what is currently being used.

 

Also CPU-z latest version is buggy IMO, I haven't changed any settings at all, and all other apps are reorting correctly the voltage +/- a little... but CPU-z was reporting that my vcore was like 2.7V at times, which would have killed the CPU for sure, when I saw that I obviously checked with other apps and in the BIOS etc and definitely still the same 1.28v - not the first time I've seen buggy voltage reporting either. I'm not trying to alarm anyone or anything, just saying if you do see much higher than expected voltage, verify via a few other apps and check in BIOS just to be on the safe side.

I've actually already created profiles for my stock + undervolt settings and OC settings.

 

Since I'm not doing anything that really needs the overclock anyway (even stock I'm still above 144 fps in the games I care about), I'm going to stay stock for the sake of CPU/mobo life until I need the extra performance. That said, the video editing performance is phenomenal with the overclock. Lol.

 

Though I wonder. 1.331v is still pretty low for Ryzen; I wonder how much life I'd be shaving off my CPU or mobo anyway. On the mobo side of things, the power phases and VRM heatsink are really only lukewarm during torture tests while overclocked, so those certainly aren't frying, and during those same tests I never saw temps higher than 75 C on the CPU. Gaming is nowhere close to those temps either. Usually like ~50'ish.

If you don't need the extra horses, then maybe not bother... but I'd definitely not let it go on auto voltage, that is attrociously over volted IMO. It shouldn't be shortening the lifespan at all IMO, look how much voltage it can kick out at stock settings. So, if you are only dialling in a reasonable OC of less than 1.45v, to be on the safe side say 1.4-ish then there should be no significant amount of life lost, if any TBH. Just have adequate cooling and make sure to run stress tests to be sure it will cope with it like that.. and that's a worst case scenario too, so running a game or whatever would never give that amount of stress, only things that come close to artificial loads are things like video rendering etc, and even then maybe not as it might depend on the GPU you have and offload some of the workload to that, also depending on the programs used too. There's many variables, but I'd say you would most likely be aware of any programs that were very CPU intensive anyway, unless it's a new program you're using.

I would leave it on OC'ed all the time if I were you, but only if you have adequate cooling etc as above, just make sure it's a stable OC first, and then monitor it while gaming to see what the average is, I would say it's not likely to be a problem.

You can correct that with llc in the bios to run at 1.2 all the time to save heat on your idle

Depends on the mobo, on b350 we haven't got access to LLC settings. On mine I don't have access to offset voltage either, so run it full throttle all the time ATM.. I will get an itx board when they finally come out with some (good ones I mean).
