" rel="nofollow - Are you using XMP to set them in the BIOS? And, so you're aware, Ryzen doesn't have a 3000 of 3400 mem divisor yet the BIOS, assuming this kit is compatible, will drop it down to like IIRC 2933 to cover no 3000 divisor |

The 3000 kit is not listed in your board's Memory QVL, no doubt due to Ryzen not supporting a 3000 speed memory divider. I see a similar model kit (4 x 8GB) at 2666, so your memory should run at that speed. If that works, try 2933. I would also skip the XMP profile, or try it but set the memory speed manually. Also, the Ryzen memory controller seems to only want to work at a Command Rate of 1T, so try setting that manually, since Auto will probably give you 2T. ------------- http://valid.x86.fr/48rujh" rel="nofollow">

Where in the BIOS would I adjust this setting? I've been scouring through it and I can't seem to find anything showing "1T", "2T", "Command Rate", or "CR". I updated to the latest stable BIOS (1.60) hoping to get my sticks up to 2933, but nothing seems to work. I know they're not on the QVL, but I was hoping the new BIOS would at least let me get to 2666. Still can't push beyond 2400. As always, your vast knowledge is very appreciated! ------------- https://valid.x86.fr/qc9lr0" rel="nofollow">

I want to say, with 99.99% certainty, that changing CR/N/T is not possible on Ryzen systems. Everything I've read doesn't mention it and even AMDs own Ryzen Master Utility doesn't. Over time an ingenuous person may make a util to do so. But BUT that assumes there's a hidden BIOS option to even toggle. And so far I haven't read or heard that changing it is possible. |

You went with 32GB, or 64GB? IIRC, it was 32GB. 4x8GB or 2x16GB? 4x8GB is quite a strain on most any IMC, AMD or Intel, to push Mhz higher, or OC with. |
