CPU: Ryzen 1600
Motherboard: Asrock B450M Pro4 (BIOS version updated to 3.50)
RAM: ADATA XPG GAMMIX D10 (2x8GB), what Thaiphoon burner reported: https://imgur.com/a/NQideja
I tried CL16-16-16-16 with 1.40V DRAM, 1.10V SOC, Gear Down enabled and Spread Spectrum disabled, still wouldn't boot to Windows: https://imgur.com/a/aH9AVVg
But the XMP 3200 MHz with CL16-18-18 is stable at 1.35V DRAM and auto SOC voltage. Is there something I'm missing? I could bump the SOC voltage up, but I've read that many motherboards may deliver a higher voltage than what the BIOS and software utilities report (Claim: https://www.gamersnexus.net/guides/3251 ... fe-voltage and someone refuting it after suspecting that the voltage measurements was done incorrectly: https://www.reddit.com/r/Amd/comments/8 ... e/dv03gjy/ ).
Update: I decided to load up the XMP profile, bump the speed to 3333 MHz with the same XMP timings, set DRAM voltage to 1.40, SOC voltage to 1.1 and enable Gear Down. I'm able to boot into Windows and currently conducting stability tests. If it works, I then plan on disabling Gear Down and run the tests again.
