Exact-match DDR5 kit for Supermicro H13SST-GC

This 192GB kit delivers two 96GB DDR5 4800 RDIMMs built to the board's precise rank, voltage and timing expectations. Registered ECC architecture lets every slot run fully populated at rated speed while correcting single-bit errors on the fly. It targets administrators who need maximum capacity on this specific platform without guesswork.

Verify manual before ordering

Server memory support varies by model and BIOS revision. Check your system or motherboard manual for approved DIMM population order, maximum capacity per slot and any firmware requirements before purchase. The 288-pin Registered form factor is mandatory; UDIMM or SODIMM modules will not fit or function.

Sustained-load behaviour

Registered buffering offloads the memory controller so all channels remain stable when fully populated under continuous workloads. ECC correction operates transparently during extended operations, preventing silent data corruption that can accumulate over time. The 1.1V operating voltage keeps power draw consistent across long-running server tasks.

Questions about this item

What comes in the 192GB kit and is anything else required for installation?

The kit includes two 96GB DDR5-4800 Registered ECC RDIMMs, part number MR38400-9624K2. No extra parts are needed; install them into the Supermicro H13SST-GC following the motherboard manual's population order.

Should I choose this 2x96GB kit or a different capacity for the H13SST-GC?

This 192GB (2x96GB) kit matches the board's DDR5-4800 Registered ECC 2Rx4 specification at 1.1V CL40. Use it when your workload needs that full capacity; otherwise select a smaller validated kit that follows the same population rules.

What does the DDR5-4800 CL40 rating mean once the modules are running in the server?

The modules operate at 4800 MT/s with a CAS latency of 40 cycles at 1.1V. Registered buffering and on-die ECC let every slot run fully populated at that rated speed while correcting single-bit errors in real time.
