48 GB DDR5-6400 ECC RDIMM for Supermicro H14DSH

This 48 GB DDR5 6400 (PC5-51200) registered ECC module is built for the Supermicro H14DSH motherboard. It runs at 1.1 V with CL52 latency and a 2Rx8 organisation. The 288-pin RDIMM form factor matches the board's registered-memory requirement. It targets administrators who need exact-spec memory that the controller recognises at full capacity and rated speed.

Exact rank, voltage and timing match

The module delivers the precise 2Rx8 rank structure, 1.10 V operating voltage and CL52 timing the H14DSH memory controller expects. Registered architecture offloads the controller so every populated slot runs at full capacity. On-die ECC catches and corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots in production workloads.

Install by the manual's population rules

Installation follows the motherboard manual's approved DIMM population order; the board will not boot if modules are seated in an unsupported sequence. No heat spreader is fitted, so clearance is standard for 288-pin RDIMM slots. Buyers who need a different capacity, a UDIMM form factor or non-ECC memory cannot use this kit.

Questions about this item

Will the 48 GB DDR5 RDIMM need any periodic maintenance or component replacement during its service life?

No routine maintenance is required for the DDR5 RDIMM itself; the module has no moving parts or heat spreader, and ECC with registered buffering corrects single-bit errors on the fly to prevent silent data corruption.

What is the first limit reached when the 48 GB DDR5 6400 CL52 kit runs under sustained load?

The module operates at the JEDEC-standard 1.1 V and CL52 latency; without a heat spreader, the DRAM temperature will hit its thermal throttle point before voltage or timing limits are reached.

How much power does the 48 GB DDR5 6400 CL52 RDIMM draw and how hot does it get when the server runs all day?

At 1.1 V the kit draws only the power defined by the DDR5 6400 specification, and with no heat spreader the chips rely on chassis airflow to stay within operating temperature.
