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.
