Server DDR5 ECC RDIMM upgrade

This 16 GB DDR5-6400 registered ECC module is built for the Supermicro H14SSF motherboard. It matches the exact 1Rx8 rank, 1.1 V operating voltage and CL52 timing the platform expects for full-speed recognition. The 288-pin RDIMM form factor ensures correct physical and electrical fit.

Sustained enterprise stability

Registered buffering reduces electrical load on the memory controller, allowing every slot to remain fully populated at the rated 6400 MT/s data rate. On-die ECC detects and corrects single-bit errors in real time, preventing silent data corruption during continuous workloads. The module maintains specified latency and voltage without throttling under prolonged stress.

Replaces slower or unbuffered memory

Upgrading from lower-speed DDR5 or non-ECC UDIMMs adds both bandwidth and error correction critical for production servers. The jump is worthwhile when your workload demands maximum capacity per channel with guaranteed data integrity. This module does not serve systems requiring unbuffered DIMMs, SODIMM form factors or speeds beyond DDR5-6400.

Questions about this item

Will the 1.1V 6400MHz RDIMM run hotter or draw more power than lower-speed modules in a fully populated Supermicro H14SSF?

At 1.10V and DDR5 6400 speed this registered ECC module operates at the standard voltage for its class, so power draw and thermal output stay within normal server DIMM limits when all slots are filled.

Does the Supermicro H14SSF require any specific BIOS setting or firmware version to recognise this 1Rx8 CL52 registered ECC RDIMM?

The module is an exact-match upgrade spec-matched to the H14SSF memory-population rules; consult your motherboard manual for supported capacities, approved DIMM order and any BIOS updates before installation.

Can I install this 288-pin registered ECC RDIMM alongside older DDR5 RDIMMs of different rank or speed in the same server?

Mixing ranks, speeds or latencies is not recommended; the H14SSF expects matched registered ECC modules per population rules, so use identical 1Rx8 CL52 6400MHz kits for stable operation.
