64 GB DDR5 4800 ECC RDIMM

This single 64 GB module delivers DDR5 4800 speed with CL40 latency and registered ECC operation at 1.1 V. It is built for the SuperMicro SuperWorkstation SYS-551A-T and compatible X13SWA-TF platforms.

Upgrade from lower-capacity or non-ECC DDR5

Replacing smaller unbuffered sticks adds 64 GB of registered capacity in one slot while keeping the 4800 MT/s data rate. The jump is worthwhile when workloads demand ECC protection and higher density per DIMM.

Fits SuperMicro server and workstation boards

The 288-pin RDIMM installs directly into supported SuperMicro motherboards without extra cooling hardware. It frees remaining DIMM slots for future expansion while providing registered signal integrity for stable operation.

Questions about this item

Will this 288-pin DDR5 RDIMM fit the memory slots on a SuperMicro SuperWorkstation SYS-551A-T?

Yes, the 288-pin DDR5 RDIMM form factor matches the DDR5 slots on the SuperMicro SuperWorkstation SYS-551A-T.

What is the correct way to seat this registered ECC module so the system recognises the full 64 GB?

Align the notch on the module with the slot key, press straight down until both retention clips click, then verify in BIOS that the 64 GB DDR5 4800 module appears at 1.1 V.

When should I expect to replace this DDR5 4800 CL40 module in a 24/7 server workload?

DDR5 RDIMMs have no scheduled replacement interval; replace only if memory diagnostics report uncorrectable ECC errors or the module fails to train at 4800 MT/s.
