Exact-match DDR5-6400 kit for Supermicro H13SSL-N

This 192 GB kit contains two 96 GB DDR5-6400 RDIMMs built to the precise rank, voltage and timing the Supermicro H13SSL-N memory controller expects. Registered ECC architecture offloads the controller so every slot runs fully populated at rated speed while correcting single-bit errors on the fly. System-specific validation eliminates guesswork for administrators upgrading this platform.

DDR5-6400 registered ECC practical limits

DDR5-6400 (PC5-51200) at CL52 and 1.1 V defines the electrical and timing envelope the modules operate within; faster speeds, lower latencies or different voltages are outside this kit's specification. The 288-pin RDIMM form factor fits only boards wired for registered memory — UDIMM or SODIMM slots will not accept these modules. Population rules in the motherboard manual determine which slots must be filled first.

192 GB capacity and headroom

Two 96 GB 2Rx4 modules deliver 192 GB total, allowing the H13SSL-N to reach high memory density with just two slots occupied. Workloads such as large database buffers, virtualisation hosts or in-memory analytics benefit from the headroom this capacity provides. Applications requiring more than 192 GB or configurations needing different rank structures would need a different kit or additional DIMMs validated for the same board.

Questions about this item

Should I choose the 192GB kit with two 96GB modules or a different capacity for my Supermicro H13SSL-N?

This kit provides 192GB total capacity using two 96GB Registered ECC RDIMMs. The 2Rx4 organization and 1.10V voltage match the motherboard's memory controller requirements for full-capacity recognition at the rated DDR5 6400 speed.

What does the DDR5 6400MHz CL52 rating actually deliver once installed in the server?

The modules run at DDR5 6400 (PC5-51200) with a CAS latency of 52 cycles at 1.10V. Registered buffering offloads the memory controller so both slots operate at full rated speed and capacity, while ECC corrects single-bit errors in real time to prevent silent data corruption.

How does the 288-pin RDIMM interface and Registered ECC design limit or enable performance in practice?

The 288-pin RDIMM form factor is the only type the Supermicro H13SSL-N accepts; UDIMMs or SODIMMs will not fit. Registered architecture allows full population at DDR5 6400 without signal degradation, and ECC provides error correction that unbuffered memory cannot.
