Exact-match DDR5-4800 ECC RDIMM kit

This 256 GB kit delivers two 128 GB registered DDR5 modules built for the Supermicro H13DSH motherboard. Each DIMM runs at 4800 MT/s with CL40 latency at 1.10 V and uses a 2Rx4 organisation. The 288-pin RDIMM form factor matches the board's registered-memory requirement exactly.

256 GB registered capacity with ECC

The dual-rank design lets the memory controller drive every slot at full speed while ECC corrects single-bit errors on the fly. Registered buffering offloads the controller so all channels stay stable when fully populated. Headroom ends at the board's maximum supported density and population rules, which vary by BIOS revision and CPU configuration.

Drops into H13DSH DDR5 slots

Installation follows the motherboard's validated DIMM population order; no heat spreader means standard airflow is sufficient. The kit frees you from mixing ranks or voltages that cause down-clocking or boot failures. Verify the manual for approved capacities and slot sequence before fitting the modules.

Perguntas sobre este artigo

Will this 256GB DDR5 4800 kit run at rated speed when installed alongside existing DDR5 4800 modules in my Supermicro H13DSH?

The kit is spec-matched to the H13DSH memory controller at DDR5 4800 CL40 1.1V 2Rx4; when populated per the motherboard manual it will operate at the rated speed.

How can I confirm the 2 x 128GB modules are recognized at full 256GB capacity after installation?

Check the BIOS memory map or operating system memory report — both should show 256GB total with each slot reporting 128GB at DDR5 4800.

Does the MR38400-724K2 package include only the two 128GB RDIMMs, or are any tools or cables required separately?

The box contains the 2 x 128GB DDR5 4800 ECC Registered RDIMMs only; no tools, cables or additional hardware are included.
