Ryzen Memory Help

Hi guys, I hope you can help me with an issue I am having.

I built my Ryzen machine a few months ago but have not been able to get my RAM up to a decent speed, I know there were a lot of issues to start with regarding memory so I waited for bios and microcode updates etc, I am running the latest bios for my board.

My system is a Ryzen 1700, MSI X370 gaming pro carbon mobo and Corsair Vengeance LPX C16 3200MHz 32gig memory kit. The fastest speed I have been able to achieve is 2800MHz but I am pretty clueless with memory to be honest so any advice will be greatly appreciated.

Thanks all.

Thank you very much for such a detailed reply, a lot of it goes over my head I must admit.

The memory kit is Corsair CMK32GX4M2B3200C16 Vengeance LPX 32 GB (2 x 16 GB) DDR4 3200 MHz C16
The label on the stick states '3200mhz 16-18-18-36 1.35v ver 5.39
Hynix M-die
2 x 16gb sticks bought as a single kit
I believe it is dual rank

Thank you very much!

Try 2933Mhz first. With 2T command rate enabled and gear down disabled. Vdimm 1.45V timings as XMP.

Soc voltage 1.125V

Thanks for your help 8 Pack, much appreciated. I tried the settings you suggested but it fails to boot unfortunately.

Try ProcOcd rate @ 53,3Ohm with timings as per label. I used manual instead of XMP profile, xmp gave me boot loop.

Thank you for your suggestion jaffveyda, I set Ohms to 53.3 as you suggested, XMP disabled, 2933Mhz with label timings, and Soc @ 1.125v and it has booted!

I have no idea how stable it is yet of course and I am not sure if I will be able to get away with pushing higher?

My board doesn't seem to like this memory kit at all, I restarted the machine and it refused to boot at 2933Mhz. I might have to get a kit with B die in the future.
