Exact-Match Server Upgrade

This 64 GB kit delivers two 32 GB DDR5 6400 Registered ECC RDIMMs built to the Supermicro H14SSL-N motherboard’s exact rank, voltage and timing requirements. The modules operate at 1.1 V with CL52 latency and a 2Rx8 organisation so the memory controller recognises full capacity at rated speed.

Who Should Buy and Who Should Not

Suits administrators expanding a Supermicro H14SSL-N platform that requires 288-pin Registered DIMMs with ECC. Not suitable for systems needing unbuffered UDIMMs, SODIMM form factors, non-ECC memory or capacities beyond the board’s validated population rules.

Capacity and Headroom

The dual-rank 64 GB configuration fills two slots and runs at DDR5 6400 without downclocking when populated per the motherboard manual. Headroom ends when the platform’s maximum supported DIMM count or total memory limit is reached, requiring a different density or motherboard to scale further.

Questions about this item

What motherboard must I already have for this 288-pin DDR5 RDIMM kit to be recognised at full 64GB capacity?

The kit is validated for the Supermicro H14SSL-N motherboard, which expects 288-pin Registered ECC DDR5 modules at 1.1V and CL52.

Will these 2Rx8 Registered modules run alongside any existing RDIMMs I keep in the other slots?

Yes, provided the board's population rules allow mixing 2Rx8 Registered DIMMs at DDR5-6400; the registered buffer and ECC function identically across matched ranks.

How can I confirm the system is operating at the rated 6400 MT/s with ECC active after installation?

Check the BIOS memory information or OS hardware report — it should show 64GB total, DDR5-6400 speed, CL52 timings and ECC enabled.
