Need help overclocking my ram

wtfishappening · March 27, 2020

Hello, I have a Ryzen 3900x on an Asrock x570 Taichi motherboard. I've equipped the machine with 4x16g ADATA XPG GAMMIX d30 sticks (not a kit, just 4 identical dimms). The ram is rated at 3200 - CL16-18-18 but in my case can only run at 2666 CL19-19-19. When I load the 3200 XMP profile my machine just dies during post. The error code the mb shows is "failed ram". If I manually set just the frequency to 3200 it works but the timings are much worse. I want to be able to run the ram at its rate of 3200. Can anyone help me with this. I'm attaching picture which show my timings. By default the ram runs on configuration titled #1 in the first picture. Ideally I'd want it to run on the XMP titled configuration. Then here are the timing as set by the XMP (but I haven't rebooted into it because as I said the machine fails post), and more secondary timings and the final of the timings. Any ideas what I might do to rectify this situation?

from your motherboard's manual:

I'f you're trying 4 sticks, you won't be able to get more than 2933. that's if the ram is single rank. is double rank, you'll get 2667.

what you can do is download and install thaiphoon burner and ryzen dram calculator and follow Method 1 in the link below.

Thanks for the reply, but if that table is correct then it means even with a single DIMM it's not possible to get more than 3200. Does that mean one of the higher end motherboards is incapable for running ram at 3200+ at all, I don't think so ? Unfortunately my system is running linux so it's not possible to run those software on linux.
