Hey guys i have a Ryzen 3600 rig with Some Micron RAM rated at 3200MHz CL16 but it will not boot. If i set ram to 3133MHz it boots just fine and pasts some test. But I've tried loosening timings and raising volts but still will not boot at 3200MHz

Any advice
 
Looks like you have a B350 motherboard so I think if it works fine on 3133MHz you'd probably better just settle for that. Your bios is up to date, right?

Have the latest BIOs and ASRock states my board supports upto 3600MHz but only with Matisse

BIOs 6.27 exactly with Agesa 1.0.0.4 Patch B
 
Are you running default timings and voltage for 3200? Or using xmp?

I was using XMP than tried manual

But i got it working thanks to a guy on reddit for finding it. But my board only supports 3200MHz and above in slots A2 & B2. The other slot would limit at 3133MHz

Alright i know i said i would try for tighter timings instead i went with higher clocks

I got 3733MHz 18-20-20-20-40

In terms of performance, you will likely want 3600 with tighter timings and a matched infinity fabric. Make sure to tweak subtimings too.


This was immensely helpful for me. Currently running micron at 3600 16-19-16-16 on a b350. Running a mix of tight and safe from that sheet.

Can you post a AIDA benchmark to compare

Try Ryzen DRAM calculator. Use Typhoon Burner to get your Ram chip details (except use the speed you are aiming for) and put them in the DRAM calculator, read XMP and hit SAFE button. Take a photo of the numbers it suggests and try at least the primaries and some of the more important secondaries. You may be able to get just a little bit more out of your RAM kit.

But yeah, Micron and Hynix do not play nice with B350, even if Zen 2 improved the Ram compatibility. Samsung B-die would have been better and much faster.

*Edit* ah, the dram calculator came up already.
