512GB DDR5 4800 ECC RDIMM kit

This NEMIX RAM kit delivers 512GB across eight 64GB DDR5 4800 registered DIMMs. It operates at 1.1V with CL40 latency and 2Rx4 organisation. ECC and registered buffering protect data integrity in Supermicro SuperWorkstation SYS-551A-T and Super X13SWA-TF systems.

Server and workstation builders needing maximum

Suited for administrators populating every slot in compatible Supermicro platforms for virtualisation, databases or large datasets. Not suited for consumer desktop boards that lack RDIMM support or for workloads requiring speeds above DDR5 4800.

Eight modules fill a full 512GB configuration

The kit comfortably handles memory-intensive server workloads across all populated channels. Headroom ends at the DDR5 4800 JEDEC limit; applications demanding higher frequencies or lower latencies will require platforms qualified for faster modules.

Questions about this item

Will the Supermicro SYS-551A-T recognise the full 512 GB across all eight 64 GB modules?

The kit provides eight 64 GB RDIMMs for a total of 512 GB; the Supermicro SYS-551A-T must support 64 GB 2Rx4 DDR5 4800 registered ECC modules to use the full capacity.

Can I add these 1.10 V DDR5 4800 CL40 RDIMMs to a system that already runs 1.1 V DDR5 4800 registered ECC memory?

Yes, if the installed memory is also DDR5 4800 registered ECC at 1.1 V with matching timings, the modules can operate together; mixed ranks or speeds will force the system to run at the lowest common settings.

How do I confirm the kit is running at DDR5 4800 CL40 with ECC active after installation?

Check the BIOS memory information or run a tool such as dmidecode — it should show 4800 MT/s, CL40, 1.10 V, registered ECC and 2Rx4 organisation for each of the eight modules.
