Hello everyone, I purchased an Asus TUF gaming B550M-plus paired with a 3900X and two HX432C16PB3K2/16 RAM sticks. The memory slots are set to QVL for use in four slots. Initially, after installing all four pairs, I encountered random problems like BSODs. Memtest86 didn’t detect any issues during a 30-minute run. I then tested each RAM stick on each slot individually. Many configurations managed to POST with different DOCP profiles (A2-B2, A1-A2-B2, just A1, just A2, just B2). However, when testing only on slot B1, swapping identical four DIMMs didn’t help. When B1 was populated, I could still POST by removing the DOCP profile. The motherboard runs the latest 1004 BIOS. I considered whether the B550M might have a problem, but wondered if there’s another cause—perhaps something with the CPU?

Increase the SOC voltage slightly to 1.1 or 1.15 and observe its effect on stability.

It seems the RAM sticks fit without a voltage ramp in slot A1, yet require more voltage for another slot. This could be due to differences in chipset support or power delivery requirements between the slots.
