Exact-match DDR5-6400 ECC RDIMM kit

This 64 GB kit contains two 32 GB DDR5-6400 registered ECC modules built to the 288-pin RDIMM form factor. It targets administrators upgrading a Supermicro H13SSL-N server who need the precise rank, voltage and timing the board's memory controller expects. The modules run at 1.10 V with CL52 latency and use a 2Rx8 organisation for full-capacity recognition across every populated slot.

Verify motherboard population rules first

Consult the Supermicro H13SSL-N manual for approved DIMM population order, maximum supported capacity per channel and any BIOS version requirements before ordering. Registered ECC RDIMMs are not interchangeable with unbuffered UDIMMs or SODIMMs, so the 288-pin registered form factor must match the board's slots exactly. Confirm that your chassis airflow and clearance accommodate the full module height without obstruction.

Registered buffering steadies heavy loads

The registered architecture buffers address and command signals, reducing electrical load on the memory controller when all slots are populated at the rated 6400 MT/s speed. ECC corrects single-bit errors on the fly to prevent silent data corruption during sustained workloads. Operating at the standard 1.10 V DDR5 voltage, the modules draw nominal power for their class and run without a heat spreader, relying on server-grade chassis airflow for cooling.

Questions about this item

What does the 64 GB kit include and is anything else required for installation?

The kit contains two 32 GB DDR5 6400 CL52 2Rx8 ECC Registered RDIMMs at 1.10 V. No extra parts are needed; the modules install directly into the Supermicro H13SSL-N DIMM slots following the board's population guide.

Why choose the 64 GB 2×32 GB DDR5-6400 CL52 kit instead of a different capacity or speed?

This exact 64 GB kit matches the H13SSL-N's qualified 2Rx8 registered ECC spec at DDR5-6400 (PC5-51200) with 1.10 V and CL52 timing, ensuring full-speed recognition in every populated slot.

What does the DDR5-6400 (PC5-51200) rating deliver once the modules are in the server?

The memory controller runs the kit at 6400 MT/s with CL52 latency and 1.10 V, providing the rated bandwidth and ECC error correction across all installed channels.
