RAM performs well at 3000 MHz but becomes unstable at 3200 MHz. Overvoltage is a known concern for memory devices.

In brief, I just assembled my PC two days ago. Here are the details: [PCPartPicker Part List](https://pcpartpicker.com/list/79xFPn)

Begin by installing RAM in slots 2 and 4. Next, you can manually tweak the DRAM voltage. If it remains unstable at 3200 with a 1.35 setting, increment the voltage by 0.01 gradually, up to a maximum of 1.45.
Isn't this just the memory they've checked? It doesn't automatically mean it's completely incompatible, does it? I might have gotten a bit carried away, but I'm in agreement. Yes, the RAM is in slots 2 and 4. I'll try raising the voltage slightly, thanks for the suggestion.
To a certain degree, these kits have been tested and confirmed to function, though not always at the advertised speed. Regarding Ryzen, I wouldn't recommend using a kit not listed on the official line. Try configuring the default memory settings in BIOS, adjust the memory voltage to 1.4, set the memory frequency to 3200, save and exit. The board will handle the timing adjustments. After startup, the timings may appear quite loose but are likely stable. I haven't performed extensive memory testing with Zen II, but during the first-gen testing I discovered some configurations with 3066MHz C14 that outperformed higher frequencies like 3200 or 3333.
DRAM Voltage (CH A/B) was the sole setting I could adjust manually. It started at 1.2V and moved to 1.25V. It appears to function correctly; I ran Memtest64 and observed no errors over about 30 iterations. With XMP it would terminate near loop 6 if configured to abort on error or crash with a blue screen if infinite loops are enabled. Game performance remains stable as well.
