A big fail (in combination with an ASUS B650 board):
My intent is using this combination with 128 GB of DDR5 (Gskill 5200 with XMP for ASUS) as ROCm development platform (with reported Ryzen compatibility). Despite that the required entities are either AMD products or reportedly compatible with AMD this usage intent is for several reasons impossible:
1) Whatever release Bios version I flash, the machine refuses to boot with the radeon pro vii installed. (No problem on an Intel Xeon workstation with PCIE3) Getting this thing working is necessary for ROCm GPU computing and thus for the intended use of the machine.
2) Installing Linux is a pain on its own. I would need to use Ubuntu 22.04 (with kernel 5.19) but installation ends up in a kernel panic with a frozen machine and is thus impossible - that would however be the second prerequisite for installing ROCm as later kernels are not supported. The only way to get the machine to load Linux and to boot is to use a combination of an old BIOS and the latest 23.04 version with kernel 6.something. Even this requires to start the installation without dedicated GPU using the internal GPU in safe graphics mode AND before rebooting to complete the installation to install an old GPU in the pcie slot. Every other approach leads to the machine either crashing in the middle of the installation a defunct graphical user interface.
If you think that this is enough suffering then you are wrong: operating this machine with Linux installed leads under standard operating conditions (no overclocking etc) to freezing after some 10 to 15 minutes such that I can only reset the machine. So what I basically have is a machine which cost me loads of money and is as solid as a house of cards. The last time I made similar terrible experiences with hardware instability and Linux problems dates back more than 20 years.
