Target System and Capacity

This 768GB kit contains twelve 64GB DDR5 registered ECC modules built for the Supermicro SuperWorkstation SYS-551A-T and X13SWA-TF motherboard. It delivers maximum supported memory density in a single validated package for memory-intensive server workloads.

Workload Fit

Suited for administrators expanding virtualisation clusters, in-memory databases or scientific compute nodes that require registered ECC stability at the platform limit. Not suited for consumer desktops, unbuffered memory slots or any system that cannot address twelve 2Rx4 registered modules.

Deciding Specification

The 4800 MT/s DDR5 registered ECC specification with CL40 latency and 1.1V operation determines compatibility; only platforms qualified for this exact speed, voltage and rank configuration will initialise the full 768GB capacity.

Questions about this item

What is included in the 768GB kit and what must be purchased separately?

The kit contains twelve 64GB DDR5 4800 CL40 ECC RDIMM modules for a total of 768GB. No additional memory components are required for a full 12-slot installation.

Should I choose this 12x64GB kit or a different capacity for my Supermicro SYS-551A-T?

Select this 768GB kit when the workstation has twelve DDR5 slots and the workload needs maximum registered ECC capacity at 4800 MT/s.

What does the 4800 MT/s rating mean once the modules are installed in the Supermicro system?

The memory will operate at DDR5 4800 (PC5-38400) with CL40 latency at 1.10V, delivering registered ECC throughput across all twelve 288-pin slots.
