Hey there! I've got this MB (Gigabyte Aorus Ultra x570) and installed four 16GB sticks totaling 64GB of RAM (G.Skill 4x16 @3200 DDR4). Only the two slots near the CPU are showing up (DDR_A1, DDR_A2), while the other two aren't visible in BIOS or Windows. Also, I'm seeing this error: "pmu memory training error at socket 0 channel 1 dimm 0 & dimm 1." I'm not using XMP and it's not working for booting, running at 3200MHz, but only at 2133MHz at half speed. Any advice on getting these slots recognized or fixing the issue would be great! Thanks.
Do you possess four identical sticks? If not, A1 and B1 serve as compartments for the same memory kind, while A2 and B2 form a second set of slots. Reorganize the memory into correct positions.
It looks like the memory channel might be faulty. Try reseating the slots and swapping the memory to determine if the issue lies with the slots or the sticks. Also, inspect the CPU and ensure no pins are bent and that the socket area is clean—no dust obstructing a pin. If none of these steps resolve the problem, it could indicate a CPU memory controller or motherboard issue.
