Exact-match DDR5 server upgrade

This 16 GB DDR5-4800 RDIMM is built for the Supermicro H13SSH-E motherboard. Registered ECC architecture and CL40 timing match the board's memory controller so the module is recognised at full capacity and rated speed. The 1Rx8 organisation and 1.1 V operation follow the platform's population rules without adaptation.

Thermals and power in normal use

Operating at 1.1 V keeps power draw low across every populated slot. The registered design buffers address and command signals, reducing electrical load on the memory controller during sustained workloads. No heat spreader is fitted, so airflow across the bare PCB handles thermal dissipation in standard server chassis.

Build quality and daily implications

Major OEM DRAM from Samsung, Micron or Hynix underpins the lifetime replacement warranty and free US-based technical support. The 288-pin RDIMM keying prevents accidental insertion into UDIMM or SODIMM slots, while ECC corrects single-bit errors before they reach production data. Verify your system manual for approved DIMM population order and maximum supported capacity before installation.

Questions about this item

How do I install this 288-pin DDR5 RDIMM in the Supermicro H13SSH-E and which slot order does the manual require?

Power down the server, open the chassis, and insert the module into the DIMM slots following the population sequence shown in the Supermicro H13SSH-E manual; the registered 288-pin form factor keys only one way, so align the notch before pressing firmly until the ejectors click.

Will the ECC registered RDIMM need any firmware updates or component swaps during its service life?

The module itself has no user-serviceable parts; ECC corrects single-bit errors automatically, and the registered buffer requires no firmware. Replace the DIMM only if the system logs uncorrectable errors or a slot fails.

What thermal or electrical limit appears first when this 1.10 V CL40 kit runs at 4800 MT/s under continuous load?

The JEDEC-rated 1.10 V operating voltage and CL40 timing define the electrical envelope; sustained full-speed operation stays within that spec, so the first limit encountered is the motherboard's maximum supported capacity per channel rather than a module thermal threshold.
