Server-grade DDR5 ECC RDIMM kit

This 384GB kit contains eight 48GB DDR5-4800 Registered ECC modules built to the 288-pin RDIMM form factor. It targets administrators expanding Supermicro H13DSG-OM servers that require registered memory with error correction for production workloads.

Replaces partial or slower memory configurations

The kit fills all eight slots with matched 2Rx8 modules at 1.1V and CL40, letting the memory controller run the full population at rated PC5-38400 speed. The jump is worth it when the board's population rules demand identical rank, voltage and timing across every slot to avoid down-clocking or capacity limits.

Installs like standard RDIMMs but demands manual

Modules seat in the 288-pin DDR5 slots without tools, yet the motherboard manual must be consulted for approved population order and maximum supported capacity per CPU. The common mistake is mixing ranks or skipping the prescribed slot sequence, which prevents the system from recognising the full 384GB.

Questions about this item

Will these 288-pin DDR5 RDIMMs fit the Supermicro H13DSG-OM motherboard slots?

Yes, the kit is built as an exact-match upgrade for the Supermicro H13DSG-OM. The 288-pin Registered DIMM form factor is the one that board requires, not a UDIMM or SODIMM.

What is the correct order to populate the eight 48 GB modules on the H13DSG-OM?

Follow the motherboard manual for supported capacities and approved DIMM population order; the kit is spec-matched to those rules so every slot runs fully populated at rated speed.

Do the modules have a heat spreader that could block adjacent DIMM slots?

No, the RDIMMs ship without a heat spreader, so they sit low in the 288-pin sockets and will not interfere with neighbouring slots.
