Exact DDR5 RDIMM kit for Supermicro H13SSL-NT

This 64 GB kit contains two 32 GB DDR5 4800 CL40 registered ECC modules built to the precise 1.10 V and 2Rx8 rank layout the board expects. The 288-pin RDIMM form factor matches the motherboard slots so the memory controller recognises the full capacity at rated speed.

Suited for administrators upgrading a Supermicro

Builders populating other motherboards or needing unbuffered UDIMM or SODIMM modules should look elsewhere. The registered ECC design and specific rank configuration are tailored to this platform's population rules and will not function in consumer or incompatible server boards.

Registered ECC with 2Rx8 organisation at 1.10 V

This combination of buffering, error correction, rank structure and voltage is the single specification that determines whether the kit will initialise correctly on the target motherboard. Verified compatibility with the H13SSL-NT ensures the modules operate at DDR5 4800 without manual timing adjustments.

Questions about this item

Should I pick the 64GB 2x32GB kit or a different capacity for my Supermicro H13SSL-NT?

The 64GB 2x32GB kit matches the board's RDIMM slots and population rules, so every slot runs fully populated at the rated DDR5 4800 speed with CL40 timing.

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

The memory controller will recognise the kit at its full 64GB capacity and operate it at 4800 MT/s with a CAS latency of 40 cycles at 1.10 V, delivering the bandwidth the platform expects.

How does the 288-pin RDIMM interface and registered ECC design affect real-world operation?

The registered architecture buffers each command, allowing all slots to run at full capacity, while on-die ECC corrects single-bit errors before they reach the OS, preventing silent data corruption.
