    ASUS KRPA-U16 not working with EPYC 7D13 (100-000000322)

    I have tried 4 different types of RDIMM's (2133, 2400, 2666 and 3200). But the 3200 is SKHynix. These chips work fine with the 7742. I have tried 1 RDIMM in each of the 8 slots one after the other with attempted power-on for each. (Motherboard manual says for 1 DIMM, put it in slot C2) I have...

    ASUS KRPA-U16 not working with EPYC 7D13 (100-000000322)

    Since this is an endless loop, I didn't note the starting code. Here are some codes that come before the loop: 15 C2 C8 63 21 dE Ad A1 34 02 50 dE etc. etc. So it seems the last code of the cycle is 50: Memory initialization error and then it begins again with dE (whatever that means). I have...

    My ASUS KRPA-U16 motherboard is working fine with EPYC ROME 7742. I upgraded the BIOS to both ROME and MILAN latest versions using BMC web ui. Upon installing the EPYC 7D13 processor it does not POST. If I replace the CPU with the original 7742 is works again. It's hard to find any info on this...
