System-specific DDR4 kit

This 128GB kit contains four 32GB unbuffered UDIMMs built for the MSI MAG B550 Tomahawk MAX WiFi motherboard. It targets builders who need maximum capacity on a consumer platform without registered or ECC memory.

DDR4 3200 CL22 limits

The modules run at DDR4 3200 (PC4-25600) with a CAS latency of 22 at 1.2V. Performance is bounded by the JEDEC-standard speed and timing; tighter latencies or higher frequencies are not supported by this kit.

128GB capacity headroom

Four ranks of 2Rx8 Samsung, Micron or Hynix chips deliver 128GB across all four slots. This fills the board completely, leaving no room for further expansion and ruling out builds that require more than 128GB or registered DIMMs.

Questions about this item

Should I buy the 128GB kit as four 32GB modules or look for a different capacity?

The kit is only sold as four 32GB modules for a total of 128GB, so choose it when you need that exact capacity.

What does the 3200 speed rating deliver on my MSI MAG B550 Tomahawk MAX WiFi?

The modules run at DDR4 3200 (PC4-25600) with CL22 latency at 1.20V on that motherboard.

Will the 288-pin DDR4 UDIMM interface limit my bandwidth?

The 288-pin DDR4 UDIMM interface caps transfer rates at the DDR4 3200 specification used by this kit.
