768 GB DDR5 kit for Supermicro servers

This six-module kit delivers 768 GB of DDR5 4800 registered ECC memory for compatible Supermicro platforms. Each 128 GB module operates at 1.1 V with CL40 latency and a 4Rx4 organisation. The kit targets administrators who need maximum capacity in supported SuperServer systems.

288-pin RDIMM modules require registered ECC slots

Modules fit 288-pin DDR5 RDIMM sockets on qualified Supermicro motherboards such as the SYS-221HE-FTNR, SYS-221HE-FTNRD and SYS-221HE-TNR. Registered signalling and on-die ECC reduce electrical load on the memory controller, freeing electrical headroom for full population. Builders must verify the platform supports 4Rx4 densities before installation.

Sustained throughput with ECC integrity

Registered buffering and error-correcting code maintain data integrity during continuous server workloads. The 4800 MT/s data rate and 1.1 V operation keep power draw stable across all six modules under prolonged load. Systems without registered ECC support or 4Rx4 compatibility cannot use this kit.

Questions sur cet article

Does the CL40 latency become a bottleneck during sustained server workloads?

CL40 is the rated CAS latency at DDR5 4800 speed; the registered design and ECC maintain signal integrity and data accuracy under continuous load.

How much heat and power does the 768GB kit produce when running all day?

Each 128GB module operates at 1.1V without a heat spreader; the registered DDR5 RDIMM design keeps power draw and thermals within standard server DIMM limits.

Which motherboard slot layout is required for the 6x128GB 288-pin RDIMM kit?

The kit needs six DDR5 RDIMM slots on a Supermicro IOT SuperServer SYS-221HE-FTNR, SYS-221HE-FTNRD or SYS-221HE-TNR platform.
