AMD slow memory training

[iSpeakVeryWell]

What board if I may ask?

X870 Tomahawk

You have me curious if its just a "some vendors" issue now.

Yeah, been wondering if it could be fixed only on 800 series board. It would be something that surprise me tho. Unfortunately I don't have a 600 series board, so I can test it.

I would not be surprised if one of those to BIOS update fixed the bug for your board.

It would be nice if AMD could give use an AGESA changelog.

For me, once my settings have trained after I made a change in the bios, it is business as usual indefinitely.. if the system has to train every time you power your system up from off, then it is unstable imo..

I was going by earlier comments that some indicated the process occurred at every boot. If not, and it really is a one and done thing, then great.

That's preciesely what the UEFI setting MCR determines. When working properly and enabled, it saves ram trainings between boots.

Did the Zen 4 slow memory training ever get fixed? Is Zen 5 improved in this regard?

Zen 4 took 5 minutes the very first boot, like my FX, it hasnt 'trained' since.

I changed i the past 30 hours to the MSI X670E gaming plus wifi mainboard from the ASUS Prime x670-p mainboard.

I think for the intital setup and configuring uefi and operating system you are out of luck. The board needs certain settings and it takes a lot of time to configure it.

... UEFI update, w11 pro installation, gnu gentoo linux restoration. Fixing boot issues, changing settings. Reset Button is here also needed as with the ASUS Prime Mainboard. This MSI mainboard has a bug with the fanspeed and ignores mainboard fan speed settings with the latest uefi update in 50% of the warm boot cases.
