CMK16GX4M2B3200C16 Hynix can't reach 3200MHz

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 :)

Could you post a screenshot of what you tried with DRAM calc?

 

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

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.
