Capacity and fit

This 1.5 TB kit supplies twelve 128 GB DDR5 modules for Supermicro SuperServer SSG-521E-E1CR24H and SSG-521E-E1CR24L systems. Registered ECC RDIMM design suits enterprise workloads that require data integrity and large memory footprints.

Build requirements

Each module runs at 4800 MT/s with CL40 latency at 1.1 V and uses a 4Rx4 organisation. The 288-pin DDR5 RDIMM form factor fits the server’s registered DIMM slots; no heat spreader is included so airflow must come from the chassis fans.

Included kit

The package delivers the full 1.5 TB in a single matched set, removing the need to source individual sticks and reducing the risk of mixing ranks or speeds. Modules are stress-tested before shipping to support stable operation in the qualified Supermicro platforms.

Questions about this item

Does the 1.10 V operating voltage limit headroom under sustained load?

The modules run at the standard DDR5 server voltage of 1.10 V; no higher-voltage headroom is specified.

How much heat do twelve 4Rx4 modules generate when the server runs all day?

The kit has no heat spreaders; cooling depends on the chassis airflow across the bare RDIMMs.

Which SuperMicro motherboards must I already own for this 1.5 TB kit to work?

Qualified platforms are the SuperServer SSG-521E-E1CR24H, SSG-521E-E1CR24L and the X13SEDW workstation board.
