AM4 B550 ATX Platform

The MSI MAG B550 TORPEDO is an ATX motherboard built on the AMD B550 chipset for the AM4 socket. It accepts Ryzen 5000 Series, 4000 G-Series and 3000 Series processors except the Ryzen 5 3400G and Ryzen 3 3200G. The board targets builders who need a full-size layout with standard mounting points.

DDR4 Speed Limits By Population

Memory runs at JEDEC speeds from 1866 to 3200 or A-XMP overclocked steps up to 4866. One rank on one channel reaches 4866, two ranks on one channel tops at 3866, and two populated channels with one rank each hit 4000. Filling all four slots with dual-rank modules caps at 3600.

Ryzen 5000 And 3000 Support Gap

The chipset enables Ryzen 5000, 4000 G-Series and most 3000 Series CPUs, yet the two 3000 Series APUs — Ryzen 5 3400G and Ryzen 3 3200G — are explicitly excluded. Verify the exact processor model before purchase.
