  • 288-pin RDIMM form factor verified for the Supermicro H13SSH memory slots

Supermicro H13SSH Upgrade Kit

This 128 GB DDR5 4800 kit contains two 64 GB Registered ECC RDIMMs built for the Supermicro H13SSH motherboard. It targets administrators who need the exact rank, voltage and timing the platform expects for full-capacity operation.

288-Pin Registered Form Factor

The 288-pin RDIMM modules match the board's required Registered architecture so every slot can be populated at the rated 4800 MT/s speed. ECC corrects single-bit errors on the fly while the buffered design offloads the memory controller for stable multi-DIMM configurations.

Sustained Enterprise Workloads

CL40 latency at 1.1 V delivers consistent throughput during extended compute tasks without the voltage headroom needed for short bursts. The 2Rx4 organization maintains signal integrity across all populated channels for reliable long-running services.

Questions about this item

What is the CAS latency of these DDR5-4800 RDIMMs under sustained load?

The modules run at CL40, which is the rated CAS latency for DDR5-4800 operation on the Supermicro H13SSH platform.

How much power do the 64 GB RDIMMs draw when the server runs continuously?

Each module operates at 1.1 V, the standard DDR5 voltage, keeping power draw low for 24/7 server workloads.

Which motherboard must I already have for this 128 GB kit to work?

The kit is verified for the Supermicro H13SSH motherboard that accepts 288-pin DDR5 RDIMMs.
