Capacity and Target System

This 768GB kit consists of six 128GB DDR5 RDIMM modules built for the SuperMicro SuperWorkstation SYS-551A-T. It delivers registered ECC memory for workloads that require data integrity and high capacity in a single compatible package.

DDR5 4800 Registered ECC Limits

The modules run at 4800 MT/s with CL40 latency at 1.1V. Registered buffering and 4Rx4 organisation add command-cycle overhead that the memory controller must support. Systems not qualified for registered DDR5 ECC will not boot with this kit.

Upgrade Path and When It Applies

This kit replaces lower-capacity registered DDR5 ECC RDIMMs in the qualified SuperMicro platform. The jump is worthwhile when virtualisation, large-dataset analytics or in-memory databases exceed the current memory ceiling and the motherboard populates all six slots.

Questions sur cet article

Is the 768GB kit the only capacity available for this DDR5 4800 CL40 ECC RDIMM?

The CSE-GS7A-2000B kit provides 768GB across six 128GB modules running at DDR5 4800 with CL40 latency.

What does the 4800 speed rating mean when the kit is installed in a Supermicro SuperWorkstation SYS-551A-T?

The modules operate at DDR5 4800 (PC5-38400) with 1.10V voltage and registered buffering for stable server workloads.

How does the 288-pin DDR5 RDIMM interface limit the maximum memory bandwidth in this system?

The 288-pin DDR5 RDIMM form factor carries the 4800 MT/s signal; registered buffering and ECC maintain data integrity at that rate.
