Support for maximum RAM on MSI B450 motherboards

However, during my search, I discovered it actually supports 128GB. I’m curious—could it be that using the newest CPU and updated BIOS allows it to support 128GB, while older CPUs and BIOS versions limit it to 64GB?

This means replacing a Zen + CPU with a Zen 2 or Zen 3 would allow you to use 128 gigabytes if you keep the Tomahawk maximum. The initial 64-gigabyte limit for B450 boards comes from the fact that they were first released with Zen +, which supported only 64 gigabytes of RAM.
