Exact-Match Server Upgrade

This 16 GB DDR5 RDIMM is built to the Supermicro H14SST-GE motherboard's exact specifications. It delivers 6400 MT/s at CL52 with a 1.10 V operating voltage and registered ECC architecture for full-capacity population.

Sustained Enterprise Stability

Registered buffering offloads the memory controller so every slot runs fully populated at rated speed without throttling. On-die ECC corrects single-bit errors continuously, preventing silent data corruption during long-running production workloads.

Pre-Installation Configuration Check

Verify your system manual for supported DIMM capacities, required population order, and any BIOS revision needed before ordering. This module is a registered RDIMM only; it will not function in boards that require unbuffered UDIMMs or SODIMMs.

Questions about this item

How much power does the 1.10V DDR5 RDIMM draw when the server runs continuously?

The module operates at 1.10V, the standard DDR5 voltage for registered ECC memory. Actual system power depends on the Supermicro H14SST-GE motherboard's memory controller and how many DIMM slots are populated.

What motherboard slot and memory type must my Supermicro H14SST-GE already have for this 288-pin RDIMM to work?

The board needs a free 288-pin DDR5 RDIMM slot. This is registered ECC memory, so the platform must support registered DIMMs and ECC — not unbuffered UDIMMs or SODIMMs.

Will this 1Rx8 CL52 registered ECC module run at 6400MHz alongside older DDR5 RDIMMs I keep in the other slots?

The Supermicro H14SST-GE memory controller sets a common speed and timing for all installed DIMMs. Mixing ranks or latencies typically forces the slowest common settings; check the motherboard manual for supported population rules.
