Exact-fit DDR5 kit for Supermicro H14DSH

This 256 GB kit contains two 128 GB DDR5-5600 RDIMMs built to the board's registered ECC specification. It targets administrators who need the full memory capacity the H14DSH can recognise at its rated 5600 MT/s speed.

Registered ECC headroom and population limits

Registered architecture lets every slot run fully populated at 256 GB while ECC corrects single-bit errors on the fly. The 2Rx4 organisation and CL46 timing meet the controller's expectations, but the kit cannot exceed the motherboard's maximum supported capacity or population rules.

DDR5-5600 interface ceiling

The PC5-44800 interface tops out at 5600 MT/s, so bandwidth is capped at that data rate. Systems requiring faster DDR5 speeds or unbuffered UDIMM modules cannot use this registered kit.

Questions about this item

Will the 2Rx4 1.1V DDR5-5600 RDIMMs run at rated speed alongside existing 1Rx8 DDR5-4800 modules in my Supermicro H14DSH?

The board will clock all installed DIMMs to the lowest common speed and apply the loosest timings across channels; mixing 5600 CL46 2Rx4 sticks with 4800 1Rx8 modules therefore forces the kit down to 4800 MHz.

How can I confirm the 256 GB kit is detected at DDR5-5600 CL46 with ECC active after installation?

Enter the BIOS or UEFI and verify the memory frequency reads 5600 MT/s, CAS latency shows 46, total capacity reports 256 GB, and ECC status is reported as enabled or active.

Does the MR44800-724K2 kit include any heatsinks, cables or installation tools, or must those be sourced separately?

The package contains only the two 128 GB DDR5 5600 2Rx4 1.1 V CL46 288-pin ECC Registered RDIMM modules; no heat spreaders, cables or tools are included.
