Exact DDR5-4800 RDIMM kit for Supermicro H13DSH

This 256GB kit contains four 64GB DDR5 4800 CL40 registered ECC modules built to 1.10V and 2Rx4 rank. The 288-pin RDIMM form factor matches the Supermicro H13DSH motherboard requirements so the system recognises the full capacity at rated speed without manual tuning.

DDR5-4800 bandwidth ceiling

DDR5 4800 delivers PC5-38400 throughput while the CL40 latency and registered buffer add one cycle per command. Full population of all slots at this speed is the practical ceiling for the platform; exceeding the rated frequency or mixing ranks will force the controller to downclock.

Verify DIMM population rules

Consult the Supermicro H13DSH manual for approved capacity per channel, required slot sequence and any BIOS version needed for 256GB operation. The board accepts only registered ECC RDIMMs; unbuffered or non-ECC modules will not function.

Questions about this item

Should I buy the 256 GB kit or a smaller capacity for my Supermicro H13DSH?

The kit provides 256 GB across four 64 GB modules, filling four slots with the 2Rx4 registered ECC configuration the board expects for full-capacity operation at DDR5-4800.

What does the DDR5-4800 CL40 rating mean when the modules are installed?

The memory runs at 4800 MT/s with a CAS latency of 40 cycles at 1.10 V, delivering PC5-38400 bandwidth while the registered buffer and ECC maintain stability under full load.

Is the 288-pin RDIMM interface compatible with my motherboard's memory slots?

Yes, the 288-pin registered DIMM form factor matches the Supermicro H13DSH's DDR5 RDIMM slots, and the 2Rx4 organization complies with the board's population rules for recognized capacity.
