Hello,
I am looking for help, after reading all of the forum posts here and trying most, if not all of the suggestions, I am now at a loss, how to proceed.
I have purchased two different DIMMs, not on the compatibility list, because none could be found or purchased. I have hooked up all three serial consoles: mainboard, MCU and RISC-V. MCU shows the voltages etc. in line with the values others have posted here. Mainboard output looks like this:

Then this serial output stops and nothing happens at all. No matter with or without SD card, with or without a Sapphire Radeon RX580 Nitro+ card plugged in. Tried three different SD card images: old Fedora linked in wiki, new Fedora livecd linked here in forums, and a debian image. Tried two different 32GB Sandisk cards.
Has anyone an idea, where I could look? I thought, if the RAM section does not show an error and saying Waiting DDR0 ECC done is a good sign, that this DIMM works, or is that not the case? Interestingy this Waiting DDR0 ECC done messages show w/o sd card and shows with debian and new fedora images, but does not show with the old fedora image linked in the wiki.
I would need to return the RAM modules this week, if they are not working…
Thanks for any tipps or suggestions!
Michael.
