What's a good, safe RAM voltage for Ryzen?
It might be a little high, but your memory should still give you about 10 years of good service that way. I wouldn't worry much, but have you tested it for stability? That is a really cool OC for a first-generation Ryzen! Get an HCI Memtest and run every memory test block at least 200 percent before you consider yourself safe. Using something like HWInfo you could also watch the DIMM temperature to see if they are getting hot during the test.
Basically, everyone I know talks about keeping those numbers under 85 degrees Celsius. I don't think you should take that literally either. What people really mean is that if you just throw something into the water too hot, it could break and cause a crazy electrical mess. But to keep your system safe, you need good air flow around your RAM sticks so they cool down properly. If you ever see those numbers creeping up like 60 or 70 degrees, then you should try to fix that by improving airflow. Here is how I got my stuff working: my two 8GB sticks are 2x8Gb b-die chips running at 1.46 volts and speeds of 3600MHz. When I push them hard with a MemTest, they stay pretty cool, hovering between the 30s and 35s, or even up to the mid-40s depending on how much stress is on them.
I have two fans right next to the ram, so it should work okay. My case is packed with fans. I just got 3333mhz at 1.35v @36c stable, but 3400 isn't stable no matter what voltage. This makes me think my SoC voltage might need to go up for 3400mhz. What do you suggest I change the SoC voltage to? What's a safe range there?
A few things might be worth thinking about: the SOC voltage is the power going to the memory controller, and just like Intel chips, you shouldn't leave this set to auto. Usually, you want something around 1.0 to 1.1 volts. Anything above that doesn't really help at all. On Ryzen processors from the 2000 series (and maybe even the 3000 series), pushing too high of a voltage like over 1.15 volts can actually make overclocking worse. "There are big differences in how memory controllers work on different CPU chips. Most CPUs will run at 3466MHz or higher when you set the SoC voltage to 1.05 volts, but the way each chip reacts changes things. Some chips get better with more voltage, while others just stop improving or even start failing faster. Every sample I tested showed trouble and errors when the voltage went up past 1.15 volts. In all cases, the highest memory speed was reached at 1.10 volts." "The Stilt said..." So...that's what you have here. I never got any success using that SOC voltage to make my 1700 cooler and more stable.
The voltage setting is already on auto mode, but the BIOS is sending out a 1.2v signal automatically. I manually changed it to 1.2v using this TweakTown page, though I might test at 1.1 or 1.15 later. Check out the guide here: https://www.tweaktown.com/guides/8506/ry...index.html
