192GB DDR5 ECC RDIMM kit for Supermicro H14SST-GE

This 192GB kit delivers twelve 16GB DDR5 registered ECC modules built to the exact timing, voltage and rank the Supermicro H14SST-GE memory controller expects. It is aimed at administrators upgrading that specific server platform to its full supported capacity with enterprise-grade reliability.

Registered 1Rx8 architecture handles full-slot

The registered design offloads the memory controller so every slot runs fully populated at rated speed, while ECC corrects single-bit errors on the fly. Headroom ends at the board's maximum qualified capacity and population rules; exceeding those limits will prevent the system from booting or running at the rated 6400 MT/s.

CL52 1.1V 288-pin RDIMM form factor

The modules use a CL52 CAS latency at 1.1V in the 288-pin registered DIMM form factor this motherboard requires. A UDIMM or SODIMM will not fit, and a different voltage or timing profile will not be recognised at full speed.

Questions about this item

Will the 12-module 192GB DDR5 6400 kit install correctly on my Supermicro H14SST-GE without changing existing DIMM order?

The kit matches the board's 288-pin RDIMM requirement and 1Rx8 registered ECC spec; follow the motherboard manual's population sequence for all 12 slots to ensure full 192GB recognition at 6400 MT/s.

How can I verify the memory is running at DDR5 6400 CL52 1.1V after installation?

Enter BIOS or use a hardware monitor to confirm the memory frequency reads 6400 MT/s (PC5-51200), CAS latency 52, and voltage 1.10 V with ECC active on all 12 modules.

Does the 12x16GB package include only the RDIMM modules or any extra parts such as heatsinks or cables?

The box contains exactly the 12 registered ECC DDR5 RDIMM modules; no heat spreaders, cables, or additional accessories are included.
