What is the maximum safe voltage for DRAM in Ryzem?
It might be a bit high, but your memory should still provide you with ten years of solid performance. I wouldn't stress about it, but have you checked for stability? That's an excellent OC choice for a 1st gen Ryzen!
Get HCI Memtest and run each memory test block at least 200% before you consider winning. Using tools like HWInfo can also help you track the DIMM temperature to see if they're getting too hot during the test.
What's too hot for RAM? It has good heat spreaders and operates at a reasonable temperature.
Most people say 'anything below 85C', but I don't mean taking that at face value. What they really mean is you're likely to become unstable and act irrationally before things get too hot. It's important to ensure your case has good airflow around the DIMMs so they stay cool, especially if temperatures rise.
The situation involves two fans close to the RAM, which is acceptable. My device has a lot of fans already. I recently received 3333mhz at 1.35v with 36c stability, but it isn't stable at 3400 regardless of voltage. This suggests my SoC voltage might need adjustment for 3400mhz. What adjustments should I make to the SoC voltage? What is a safe range?
Here are a few relevant quotes:
"SOC voltage refers to the voltage to the IMC, and similar to Intel, it's not advised to keep it on auto. Generally, you aim for 1.0 - 1.1v; above 1.1v offers little benefit.
On Ryzen 2000 (possibly 1000 and 3000 as well), values over 1.15v can hinder overclocking."
"Significant variations exist in how the memory controller functions across various CPU models. Most CPUs maintain 3466MHz or higher at a 1.050V SoC voltage, but the response differs. Some models scale with increased SoC voltage, while others either don't scale or even show negative scaling. All tested samples exhibited negative scaling—more errors or training failures—when a SoC voltage above 1.150V was used. In every case, the highest memory frequency was achieved at ≤ 1.100V SoC voltage."

The SOC voltage was set to auto, yet it consistently displayed 1.2v based on the bios. I adjusted it manually to 1.2v following the instructions on that TweakTown page, but I plan to test 1.1 or 1.15 next.
Keep this in mind: when adjusting voltages, ensure monitoring comes from within the OS using a suitable tool...such as HWInfo64. The voltage displayed in the BIOS won't match the actual reading during OS boot. This discrepancy occurs because the CPU in BIOS runs on a single core while the OS's power management isn't active. It doesn't reflect the environment inside the operating system.
