  • 288-pin RDIMM form factor fits the Supermicro H13SST-GC motherboard exactly

Exact DDR5-4800 Registered ECC Kit

This 32 GB kit contains two 16 GB DDR5-4800 RDIMMs built to the 288-pin Registered ECC specification. It targets administrators upgrading a Supermicro H13SST-GC motherboard with modules that match the board's required rank, voltage and timing profile.

Capacity and Headroom

The dual-rank kit delivers 32 GB of error-correcting memory at 1.1 V and CL40, allowing fully populated slots to run at rated speed without overloading the memory controller. Workloads that exceed this capacity will require additional DIMM slots or higher-density modules not included here.

Upgrade Context

It replaces non-ECC or unbuffered modules that cannot be recognised by the server's registered memory controller. The jump is worthwhile when the platform demands Registered ECC DDR5-4800 1Rx8 DIMMs for stability and data-integrity requirements.

Questions about this item

Will the 288-pin RDIMM modules fit and run alongside any existing DDR5 RDIMMs I keep in my Supermicro H13SST-GC server?

Yes, each 16 GB module is a 1Rx8 DDR5 4800 Registered ECC DIMM at 1.10 V CL40, matching the board's required rank, voltage and timing so mixed populations are recognised at full speed.

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

Check the BIOS memory information or OS tools such as dmidecode; they should report 4800 MT/s, CL40, 1.10 V, Registered and ECC enabled for both 16 GB modules.

What exactly ships in the box and is anything else required to use the memory?

The package contains two 16 GB 288-pin DDR5 RDIMMs for a total of 32 GB; no additional parts are needed — just install them into the approved slots per the motherboard manual.
