  • 32 GB DDR5-4800 registered ECC RDIMM fits Supermicro H14DSG-O-CPU exactly
  • 2Rx8 organisation and CL40 timing let the memory controller run every slot at rated speed
  • Registered architecture offloads the controller so full population stays stable under load
  • On-die ECC detects and corrects single-bit errors preventing silent data corruption
  • 10 V operation meets the board's voltage spec for reliable server deployment

Exact-match DDR5 upgrade for Supermicro H14DSG-O-CPU

This 32GB DDR5-4800 module is built to the precise rank, voltage and timing the server memory controller expects. The 2Rx8 registered ECC design ensures full-capacity recognition and rated-speed operation without manual tuning. It fits the 288-pin RDIMM slots this motherboard requires.

Capacity and headroom in a single DIMM

The 32GB density lets you add substantial memory per slot, useful for virtualization hosts, database buffers or large file caches. Registered architecture offloads the controller so every populated slot runs at the full 4800 MT/s data rate. A single module stops at 32GB; larger per-slot capacities would require different DIMMs.

DDR5 interface practical limits

DDR5 at 4800 MT/s (PC5-38400) delivers the bandwidth this platform specifies, with on-die ECC and 1.1V operation built into the standard. Registered buffering allows full-slot populations without signal degradation. The motherboard's memory-population rules still dictate maximum total capacity and supported configurations.

Questions about this item

Will the 2Rx8 registered ECC DDR5 module work in the remaining DIMM slots of my Supermicro H14DSG-O-CPU alongside existing memory?

The module is an exact-match 32 GB DDR5-4800 2Rx8 registered ECC part built for the H14DSG-O-CPU, so it will be recognised at full capacity and run at its rated speed when installed in a supported slot configuration.

How can I confirm the CL40 1.1 V DDR5 module is running at 4800 MT/s after installation?

Enter the BIOS or use a tool such as dmidecode; both will report the module operating at DDR5-4800 (PC5-38400) with CL40 latency at 1.1 V.

What comes in the box and do I need any extra parts to install it?

The package contains the 32 GB DDR5 4800 MHz 2Rx8 1.1 V CL40 288-pin ECC RDIMM itself; no heat spreader, cables or additional hardware are included or required for installation.
