Question Seemingly weird Ryzen 5 Voltages

[epiczombiekill]

I just upgraded to a Ryzen 5 1600x and was curious about the voltages I'm seeing in HWmonitor

At idle I'm seeing 1.4-1.46v, but under load with P95 I'm seeing 1.2v, temps are a tad high at idle 40c-48c though under full load at 4.1ghz it doesn't go above 70c
Everything in the bios is stock other than some custom fan curves

I've heard 1.4v+ is dangerous for these so I wanted to check to make sure it's safe, though I ran my 4690k at 1.45v for the better part of a decade so I'm assuming as long as temps stay in check it will be fine, but any advice/info would be greatly appreciated

Thank you all in advance

Hey there,

What mobo are you running, and what bios version?

I'd suggest by starting with a vcore offset. If you are hitting 1.4+ regularly at idle, then you could use an offset like 0.10, which would bring the voltage down to about 1.3 which should be fine to run the chip at all core load (3.9ghz)

Just to be clear, running Prime95, you are only hitting 70c? You need to test the CPU with small FFT's for stability testing. I suspect your temps will go very high, up to 80+. What cooler do you use?

Forget comparing to older Intel CPUs,things have changed since then, for Intel as well as AMD.
First Ryzen series are good up to 1.5v without any danger. It's normal for voltage to be high at idle. it ensures stability but it doesn't run at high power so that's fine. It's also normal for voltage to drop under load (Voltage droop) because power goes up and what counts is Watts which is actual value for work.
Which cooler are you using, 1600x doesn't come with factory cooler ?
1600x boost works best up to 60c, if it reaches over, boost drops and performance is lost. so you may need larger cooler.

After doing some digging I'll probably just leave it alone, the motherboard is a GA-AB350M-DH3 with the most recent bios

As far as cooling goes I'm using the stock aluminum AM4 cooler with the copper core, with MX-6, as of an hour of testing on it tops out at 74.8c on small fft, the 5c difference is because I got tired of hearing my Jetflos @100% and turned them down a couple days ago

I'm also not entirely sure a voltage offset is an option in this bios, though it's very possible I missed it but I'm not super worried about it, other than I'll probably find an AM4 compatible bracket for my old 212 Evo, unless there's something better nowadays

That's actually pretty interesting, though I hadn't read anywhere else about boost working best up to 60c, but that would make some sense since in games it seems to top out around 60c

I'm using MX-6 with the stock aluminum/copper core heatsink though I'll probably get a compatibility kit for my 212 Evo soon just to get the temps well below 60c for the summer, at least I'm assuming it will since it kept my 4690k@5Ghz around 75-80c

Thank you btw I really appreciate the information, I've never regretted waiting to upgrade so much, and this was just the cheapest option I could find second hand after my Devils Canyon died

1600x was my first Ryzen. bought it first day when i became available to replace Fx 8350 system. Run it on Asus prime x370 pro and 16GB of 3000MHz RAM. Later on I gradually upgrade to 2700x, 3700x and 5800x (on x470 MB) as they became available. i experimented a lot and being an old time (since 386) overclocker started tuning then rightaway. Because it didn't come with factory cooler (only non-x did). I used series of AIO coolers. as I upgraded CPUs. First CM Nepton 140XL and 240 and 360 Arctic. From very beginning, temperature was a guide for it' s performance in auto modes. all until 5800x run best (frequency boost) up to 60c, except a bit of tuning with PBO and voltage, nothing else was done or produced any better erformance, just good cooling. Zen3 (5000 series) although officially (by AMD) 90-95c are actually best with some 10c less than that.
Unlike older CPU generations, frequency boost is sudden and fast so voltage and temps are also "nervous" and correspond to them. So best start is to cool them at least a bit more than absolutely neccessery.
