Atrocious DDR5 overclocking results with Hynix A-Die and Ryzen 7500F.

By


Hi.

I've ran into an issue with my RAM during overclocking. 1x16GB 6000Mhz CL36 Kingston Fury paired with ASRock B650M-HDV/M.2 and Ryzen 7500F.

I've tried to run timings similar to what Buildzoid was able to achieve here: https://youtu.be/4W3q0YzjQww?si=zhSyryuqAmxuP8OX&t=2434 6200Mhz CL30-38-38-30-68 1.42V 2100Mhz IF 1.3V SoC with all the subtimings.

Not only i wasn't able to get the PC to POST, but also things i've tried and anything other than EXPO profile just didn't work.

  • 6200Mhz CL30-38-38-30-68 1.42V 2100Mhz IF – failed
  • 6200Mhz CL32-38-38-48-86 1.42V 2100Mhz IF – failed
  • 6000Mhz CL32-38-38-48-86 1.43V 2000Mhz IF – failed

I've also tried booting up 6000Mhz CL32-34 with tRAS and tRC loosened up by a lot – no success, that's where i gave up. By looking at the results of others, this memory should've ran on at least 6000Mhz CL30 by giving it very little tweak on the very same board. I've updated my BIOS to the newest version – 3.20, since the one with which the board came in was pretty old and i know early AM5 rigs were having issues with memory clocked higher than 6000Mhz.

I'm just running out of ideas. Is there some subtiming screwing me over? Is it software issue? Should i go back to older BIOS? Is it hardware issue? Is one stick somehow harder to overclock? It's pretty hard to believe the CPU itself is uncapable of running even 6000Mhz with decent timings.

    What slot are you using? It should be in B1 for one stick only. But you really are giving up a lot by not using a 2 dimm kit because there is another memory channel going unused.

    Its micron, not hynix Adie, so no cl, You can tighten secondaries/terries and be good.

    You say it’s a Kingston 6000 MT/s rated at CL36, that doesn’t necessarily have to be a Hynix-based DIMM. If it’s rated 6000 36-36-36 in particular, it’s very likely going to be a Samsung-based DIMM.

    Is it KF560C36BBEK2-32 ? if it is it’s M die
    If not you have probably a micron/samsung stick.

    look at the sticker; mm ms mh for micron, Samsung , hynix

    the error is tryng to overclock a micron chip
