Exact-match server upgrade

This 288GB kit contains six 48GB DDR5 RDIMMs rated at 4800MHz PC5-38400 with CL40 timing and 1.10V operation. The modules use a 2Rx8 registered ECC design built with major OEM DRAM chips and are validated for the Supermicro H14DSG-OM motherboard.

Registered ECC stability

Registered buffering reduces electrical load on the memory controller so all six slots can run fully populated at the rated speed. On-die ECC detects and corrects single-bit errors in real time, preventing silent data corruption and unplanned reboots in production workloads.

DDR5 RDIMM constraints

The 288-pin RDIMM form factor fits only motherboards wired for registered DDR5 memory; it will not seat in UDIMM or SODIMM slots. Population rules, maximum per-slot capacity and supported ranks vary by platform, so the system manual must be consulted before installation.

Questions about this item

Will the 2Rx8 RDIMM modules need any firmware updates or thermal-pad changes later?

No firmware or thermal-pad changes are required; the registered ECC DDR5 DIMMs run at the rated 1.1 V and CL40 without further intervention.

What limit appears first when all six 48 GB modules run continuously at 4800 MT/s?

The memory controller on the Supermicro H14DSG-OM board will hit its maximum supported capacity and channel population before any module timing or voltage limit is reached.

How much noise and heat do the bare 288-pin DDR5 sticks produce under all-day load?

With no heat spreaders the modules rely on chassis airflow; at 1.1 V typical DDR5 power per 48 GB stick stays low, so audible fan noise comes only from the server fans, not the memory itself.
