Exact-match DDR5 kit for Supermicro H14SHM

This 256 GB kit contains two 128 GB DDR5 5600 RDIMMs built to the Supermicro H14SHM memory controller specification. Registered ECC with 2Rx4 organisation and CL46 timing at 1.1 V ensures the board recognises full capacity at rated speed. Major OEM Samsung, Micron or Hynix chips provide enterprise-grade stability.

Standard 288-pin RDIMM installation

Modules seat in the server's DIMM slots like any registered DDR5 RDIMM; no heat spreader is fitted so clearance is minimal. The critical step is following the motherboard manual for population order and maximum supported capacity per channel. Incorrect slot order or exceeding the board's validated configuration are the typical reasons a kit fails to post.

Suited for H14SHM memory expansion

Ideal for administrators expanding a Supermicro H14SHM platform that requires registered ECC DDR5 at 5600 MT/s in a 2Rx4 layout. Not appropriate for systems that need unbuffered UDIMMs, SODIMM form factors, lower voltages, different speeds, or non-ECC operation.

Questions about this item

How do I confirm the kit is running at DDR5 5600 CL46 after installation?

Check the BIOS memory information or a tool such as CPU-Z; it should show 5600 MT/s and CAS latency 46 with both 128 GB modules detected for 256 GB total.

What comes in the box and is anything else required?

The box contains the 256 GB kit — two 128 GB 288-pin DDR5 RDIMMs. No extra parts are needed; the modules plug directly into the Supermicro H14SHM motherboard.

Why choose the 256 GB 2Rx4 CL46 version over other capacities?

This 2Rx4 registered ECC kit matches the H14SHM’s qualified population rules for full-capacity operation at 5600 MT/s and 1.1 V, which other ranks or speeds may not support.
