Purpose-Built Server Memory Kit

This 384 GB kit consists of four 96 GB DDR5 RDIMMs rated at 6400 MT/s with CL52 latency and 1.1 V operation. It targets administrators upgrading a Supermicro H13DSG-OM platform that requires registered ECC modules in a 288-pin form factor.

Upgrade Path and Compatibility

The kit replaces any lower-capacity or slower DDR5 RDIMM set currently installed in the H13DSG-OM, delivering the exact rank configuration and voltage the board's memory controller expects. The jump is worthwhile when the workload demands the full 384 GB at rated speed across all populated slots without downclocking.

Build Integration

Each module uses a 2Rx4 registered ECC design that offloads the memory controller, allowing full population while correcting single-bit errors on the fly. The 288-pin RDIMM form factor fits only boards wired for registered DDR5; it will not work in UDIMM or SODIMM slots. Verify the motherboard manual for approved population order before installation.

Questions about this item

Will the 288-pin DDR5 RDIMM modules fit the Supermicro H13DSG-OM motherboard slots?

Yes, the kit uses 288-pin DDR5 RDIMM form factor which matches the Supermicro H13DSG-OM motherboard requirements. The registered ECC design is exactly what this board expects for full-capacity operation.

What is the correct installation order for the four 96GB modules on the H13DSG-OM?

Install modules following the motherboard manual's DIMM population sequence for 4 DIMMs per channel. The 2Rx4 rank structure and CL52 timing require exact slot placement so the memory controller initialises all 384GB at DDR5-6400 speed.

Do these 1.1V DDR5 RDIMMs need active cooling or heatsinks over time?

The modules ship without heat spreaders and operate at standard 1.10V. In a properly ventilated server chassis the registered design runs within thermal limits, so no extra cooling or heatsink retrofits are required during their service life.
