MikeOne Posted August 9, 2020 Share Posted August 9, 2020 (edited) 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 :) Edited August 10, 2020 by MikeOne Link to comment Share on other sites More sharing options...

The 1200AF is a Zen+ CPU, it should be capable of DDR4-2933 as far as I am aware. https://en.wikipedia.org/wiki/Zen%2B Edited August 10, 2020 by A Computer Guy Link to comment Share on other sites More sharing options...
MikeOne Posted August 10, 2020 Author Share Posted August 10, 2020 (edited) 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 Edited August 10, 2020 by MikeOne Link to comment Share on other sites More sharing options...
LeDoyen Posted August 10, 2020 Share Posted August 10, 2020 did you build the computer with these sticks or did you upgrade them on an existing build? I often find that during upgrades, some secondary timings were not changed when selecting the XMP profile, and the bios keeps those of the old kit, causing BSODs or failure to boot. I usually solve this by going back to the default ram settings, applying, restarting to bios, re-enabling XMP, and then they are all set correctly.

MikeOne Posted August 10, 2020 Author Share Posted August 10, 2020 (edited) 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. Edited August 10, 2020 by MikeOne Link to comment Share on other sites More sharing options...
geraldleb Posted August 20, 2020 Share Posted August 20, 2020 Solved using suggestion found on forum. Enable xmp. Make sure xmp timing settings are correct. However change or set trC to 56. Voltage to 1.35. Multiplier to 32. Stable 3200 performance in w10 pro on x570 board ryzen 9 3900x. Link to comment Share on other sites More sharing options...
