768GB DDR5 ECC RDIMM kit for Supermicro servers

This 768GB kit contains twelve 64GB DDR5 4800 RDIMM modules built for Supermicro SuperWorkstation SYS-751A-I and Super X13DAI-T platforms. Each module runs at 1.1V with CL40 latency and 2Rx4 organisation. The registered ECC design targets enterprise workloads that require data integrity and high capacity.

Twelve-module kit simplifies large-capacity

The 12x64GB configuration fills twelve DIMM slots in a single validated package, removing the need to source and match individual sticks. Registered buffering and on-die ECC reduce electrical load on the memory controller while correcting single-bit errors. No heat spreaders are fitted, so airflow clearance follows the server chassis design.

Suits IT teams scaling Supermicro workstations

Buyers who need maximum registered ECC capacity on the listed Supermicro platforms will use every slot. Teams requiring lower densities, non-ECC memory, or compatibility with other motherboards should select a different kit.

Questions about this item

Will the 12 modules need any firmware updates or active cooling added later?

The kit contains 12 registered DDR5 RDIMM modules without heat spreaders; no firmware updates are required and the motherboard's standard airflow is the only cooling needed.

What limit appears first when all 768 GB run at 4800 MT/s continuously?

The memory controller's maximum supported capacity and rank population rules for the Supermicro SYS-751A-I platform will be reached before bandwidth or voltage limits.

How much power and heat do the 12 sticks produce at 1.1 V under 24/7 load?

Each 64 GB 2Rx4 module operates at 1.10 V, so the full kit draws roughly 12 × 64 GB × 1.1 V; registered buffering keeps signal integrity stable without extra heat.
