I have a brand new MSI MPG B550 Gaming Plus motherboard, which is working great, except for the fact I can't get it to register more than 32GB of RAM. It should support up to 64GB.
I have 2x 16GB Corsair (https://www.amazon.nl/dp/B01CYILUB8/) sticks which work great in DIMMA2/DIMMB2 and show up as 32GB.
If I put 2 more sticks of the same module in the second RAM lane (DIMMA2/DIMMB2) it fails to boot, and the motherboard debug light is stuck on CPU.
I have tried rotating the RAM in all the combinations and I still can't get it to boot with more than 32GB of RAM.
The debug light seems to indicate that there is a problem with the CPU. I have tried loosening up the CPU cooler by a half-turn to see if their was a bad connection on one of the pins, but no luck.
I thought maybe there was a setting in the BIOS to enable the 2nd lane of RAM but I can't find any such setting. I also flashed the latest BIOS to the motherboard.
Is the 2nd memory controller/lane just broken on this CPU? (AMD Ryzen 5 5600X).
Any other options to debug or is this simply a bad CPU/motherboard?
Thanks in advance.
