The motherboard and gpu are refurbished :/ I'm running now 2800 14 14 14 14 32 at 1.25v stable. I've tried 2933 but it show errors in memtest.

Not sure if im doing right in DRAM Calculator, i've tried this. I was wrong, ive search that is Nanya A DIE, not Hynix :/ I've found this datasheet with same memory: https://docs.google.com/spreadsheets/d/1dsu9K1Nt_7apHBdiy0MWVPcYjf6nOlr9CtkkfN78tSo/edit#gid=527992713

Hi, I've a CMK16GX4M2B3200C16 Hynix (Edit: NANYA A DIE) (2x8GB) and can't reach 3200MHz CL16. Mobo MSI B450m Gaming Plus, Ryzen 1200AF OC 3.8 1.25v, PSU Corsair CV550 and GPU RX470 4GB Mining OC 1310MHz 940mv. With XMP profiles always get BSOD or exit games, manual mode fail anything above 2800MHz. I've tried SoC 1.15, Ram voltage up to 1.4v, used DRAM Calculator... nothing seems to work properly. The best i can get stable is: 2800MHz at 1.25v SoC 1.05v and CL 14 16 16 16 32. This is about the same latency of 3200 at c16, 10ns. Should I keep trying to reach 3200 or is enough on this config? RMA? Is CPU problem up to 2666 on specs? Ty a lot for your help :)
