192GB DDR5-6400 ECC RDIMM kit

This 192GB kit contains two 96GB DDR5-6400 registered ECC RDIMMs built for the Supermicro H14SSL-NT motherboard. It targets administrators upgrading memory capacity in compatible Supermicro servers while maintaining registered buffering and error correction. The modules operate at 1.1V with CL52 latency and a 2Rx4 organisation. Buyers needing non-ECC UDIMMs or SODIMM form factors should look elsewhere.

Registered ECC headroom at 192GB

The 2Rx4 registered design offloads the memory controller so all populated slots run at the rated 6400 MT/s speed with ECC active. Single-bit errors are corrected on the fly to prevent silent data corruption and unplanned reboots in production workloads. Capacity scales to the full 192GB kit when the board's population rules are followed; exceeding the motherboard's validated DIMM-per-channel limits will reduce speed or prevent boot.

288-pin RDIMM fit for Supermicro H14SSL-NT

These 288-pin RDIMMs match the exact form factor and electrical spec the H14SSL-NT requires — no UDIMM or SODIMM alternative will seat correctly. Consult the system or motherboard manual for approved DIMM population order and maximum supported capacity per slot before installation. The kit frees you from mixing mismatched modules and delivers a validated upgrade path for the target platform.

Questions about this item

Will the 2Rx4 registered ECC DDR5-6400 modules run at full speed alongside existing DDR5 RDIMMs in the Supermicro H14SSL-NT?

The kit is an exact-match upgrade spec-matched to the board's memory-population rules; consult your motherboard manual for supported capacities and approved DIMM population order before mixing modules.

How can I verify the 192GB kit is recognized at full capacity and rated speed after installation?

Check the system BIOS or UEFI memory information screen — it should show 192GB total, DDR5-6400 (PC5-51200), CL52, 1.1V, and registered ECC operation across both 96GB modules.

What is included in the box and what must be purchased separately for installation?

The package contains the 192GB kit (2 x 96GB DDR5-6400 2Rx4 1.1V CL52 288-pin ECC RDIMMs); no heat spreaders, cables, or additional hardware are included, and nothing else is required for installation.
