I got my Ryzen 5 2600 to a stable 4GHz, but it took 1.3875v to do it. My question is; is that OK for everyday use? Gaming? What's too high?

Is that VCore, or Core Voltage (STI2 TFN)? one is the VCore output of the VRM... the other (STI2 TFN) is the actual core voltage inside the CPU. You can see them separately using HWInfo64. On some boards they read very close all the time, others not so much. It just depends on where the VRM sense point is.

With my SoC voltage at 1.1375v and VCore at 1.32v, LLC Mode 1 (MSI b450m gaming plus) I have a stable 4.0 Ryzen 5 2600, at <65c under load (Rosewill RGB single rad AIO.)

I tested as high as 1.42v with as low as 4.05mHz and couldn't get more than a minute into prime95 without errors. I most definetly lost the silicone lottery there.

But to get back on subject, try adjusting your Load Line Calibration, and upping your SoC voltage just a little to try to back down on the VCore voltage a bit.

Also, what are you using for cooling?

I did a bunch of bench runs last week on a very low quality same R5 1600. It took over 1.55vCore to stabilize 4GHz for benching and nearly 1.28vSoC and 1.45vDIMM for DDR4-3466CL14. Ran like a champ though.

I don't know. Whatever Ryzen Master uses in the section referred to as Voltage Control (V)/CPU Voltage.

I'm using a Cooler Master Hyper 212 Black Edition. Temps never got out of the high 60cs running Intel Burn Test except for a momentary spike into the low 70Cs once or twice. I've been gaming with it for awhile since and all seems normal, including temps. I just had no idea what to consider safe for voltage is all.

I'm not as well-versed at this as you guys, so I'm probably not going to get that deep into the weeds. Just wanted a safe 4GHz.

1.33-1.38v is the max recommended safe voltage for zen+. Your 2600 seems to need a ridiculous amount of vcore to reach 4ghz, most 2600's can do that with 1.25v.
What motherboard are you using? My old gigabyte b350 d3h needed 1.35v for 3.9ghz and on my current asus board I only need 1.3v for 4.02ghz.
