1.5 TB DDR5 ECC RDIMM kit for Supermicro

This 12-module kit delivers 1.5 TB of DDR5 4800 registered ECC memory in 128 GB modules. It is built for Supermicro SuperWorkstation SYS-551A-T and Super X13SWA-TF platforms. The registered design and ECC support target mission-critical server and workstation workloads.

Upgrade from lower-capacity DDR5 RDIMM sets

Replacing smaller kits with this 12 x 128 GB configuration raises total system memory to 1.5 TB without mixing module densities. The jump is worth it when virtualization, large databases or scientific computing demand maximum registered ECC capacity on supported Supermicro motherboards.

Suits IT teams running memory-intensive Supermicro

Engineers who need 1.5 TB of validated DDR5 4800 ECC RDIMM memory for compatible Supermicro workstations will benefit. Builders using consumer motherboards, non-ECC platforms or systems limited to fewer than 12 DIMM slots should look elsewhere.

Questions about this item

Does this 288-pin DDR5 RDIMM kit fit the Supermicro SuperWorkstation SYS-551A-T?

Yes, the 12-module kit is built for that workstation and uses the 288-pin DDR5 RDIMM form factor the board requires.

What is the correct slot population order when installing all twelve 128 GB modules?

Fill every DIMM slot in the sequence shown in the system manual; skipping a channel or mixing ranks will prevent the 1.5 TB configuration from posting.

When should the twelve 4Rx4 modules be replaced if ECC correctable errors start appearing?

Replace the affected module once the system logs show a rising correctable-error count on any of the 12 sticks, as continued use risks uncorrectable failures.
