32GB DDR5-4800 Registered ECC RDIMM

This 32GB DDR5 module runs at 4800MHz with CL40 latency and 1.1V operation. It is built as a 2Rx8 Registered ECC RDIMM for the Supermicro H14DSG-OD motherboard. The exact rank, voltage and timing match the board's memory controller so the module is recognised at full capacity and rated speed. It targets server administrators who need validated, single-slot upgrades for this platform.

Capacity and headroom

The 32GB density adds a large block of ECC-protected memory per slot, letting the H14DSG-OD reach higher total capacities when multiple slots are filled. Registered buffering offloads the memory controller so every populated slot runs at the full 4800MHz data rate. Headroom ends when the board's maximum supported DIMM count or total memory limit is reached, which varies by BIOS revision and CPU configuration.

Build integration

The 288-pin RDIMM form factor fits only DDR5 RDIMM slots; it will not work in UDIMM or SODIMM sockets. No heat spreader is fitted, so airflow across the modules must come from the chassis or CPU cooler. ECC and registered operation free the memory controller from electrical load and correct single-bit errors on the fly, reducing unplanned downtime. Consult the motherboard manual for approved population order and maximum supported capacity before installation.

Questions about this item

Will the 2Rx8 registered ECC DDR5-4800 module work in the remaining slots of my Supermicro H14DSG-OD alongside existing RDIMMs?

The H14DSG-OD requires registered ECC RDIMMs; this 2Rx8 CL40 1.1V DDR5-4800 kit matches that spec. Populate slots in the order shown in the board manual so the memory controller trains all channels at the rated speed.

How can I confirm the kit is running at DDR5-4800 CL40 with ECC active after installation?

Enter the BIOS and verify the memory frequency reads 4800 MT/s, CAS latency 40, voltage 1.10 V, and that ECC is reported as enabled. The OS should also show the full 32 GB capacity with no correctable-error warnings.

Does the package include only the 32 GB DDR5 RDIMM or are any cables, brackets or licences supplied?

The box contains the single 32 GB 288-pin DDR5-4800 2Rx8 registered ECC RDIMM. No cables, brackets, heat spreaders or software licences are included.
