384GB DDR5 RDIMM kit for Supermicro servers

This 384GB kit contains four 96GB DDR5-4800 registered ECC modules built to the exact timing and voltage the Supermicro H14DSG-OM motherboard expects. It targets administrators who need maximum supported capacity on this platform without mixing ranks or speeds.

Registered ECC architecture handles full

The 2Rx4 registered design offloads the memory controller so all four slots run at 4800 MT/s with CL40 latency and 1.1 V. ECC corrects single-bit errors on the fly, preventing silent data corruption in production workloads. Capacity headroom ends at 384GB; larger configurations require a different motherboard or DIMM density.

288-pin DDR5 RDIMM form factor decides fit

Only motherboards that accept 288-pin DDR5 registered DIMMs with 2Rx4 organisation and 1.1 V operation can use this kit. Systems requiring unbuffered UDIMMs, SODIMMs, different voltages, or other DDR generations will not recognise these modules.

Questions about this item

Will the 2Rx4 96GB modules run with my existing DDR5 4800 RDIMMs in the Supermicro H14DSG-OM?

The kit uses 2Rx4 registered ECC at 1.1V and CL40. Matching those exact specs — rank, voltage and timing — lets the memory controller recognise the full 384GB at rated speed.

How can I confirm the 384GB kit is operating at DDR5 4800 with ECC active after installation?

Check the BIOS memory information screen: it should show 384GB total, 4800 MT/s, CL40 and ECC enabled for each 96GB DIMM.

Does the MR38400-9624K4 package include anything besides the four 288-pin RDIMMs?

The box contains only the four 96GB DDR5 4800 CL40 1.1V ECC registered RDIMMs; no heat spreaders, cables or tools are included.
