NEMIX RAM 192GB DDR5 ECC RDIMM kit

This NEMIX RAM kit supplies 192GB of DDR5 memory across twelve 16GB registered DIMMs. It operates at 4800MHz with CL40 latency and 1.10V voltage. The modules use 1Rx8 organisation and ECC for data integrity in compatible Supermicro platforms.

Suited for Supermicro SYS-551A-T

Builders expanding a Supermicro SuperWorkstation SYS-551A-T or Super X13SWA-TF motherboard can install this validated kit directly. Systems that require unbuffered UDIMMs, non-ECC memory, or a different DDR generation cannot use these registered modules.

Registered ECC RDIMM with 1Rx8 organisation

The registered buffer and ECC function are mandatory for the target Supermicro platforms. A motherboard that accepts only unbuffered non-ECC DIMMs will not work with this memory.

Questions about this item

Does this 192 GB DDR5 4800 CL40 288-pin ECC RDIMM kit require a Supermicro X13SWA-TF motherboard with DDR5 slots to operate?

Yes — the kit is built for Supermicro SuperWorkstation SYS-551A-T and X13SWA-TF platforms that provide DDR5 RDIMM slots and registered ECC support.

Can I keep my existing DDR5 4800 CL40 1Rx8 registered ECC modules and add this 12-module kit alongside them?

Mixing is possible only if the other modules match 4800 MT/s, CL40, 1.10 V, 1Rx8 organisation and registered ECC; otherwise the system will default to the slowest common settings or fail to POST.

How can I confirm the full 192 GB kit is running at DDR5 4800 CL40 with ECC active after installation?

Enter the BIOS or use a tool such as dmidecode / CPU-Z to verify each of the 12 slots shows 16 GB, 4800 MT/s, CL40, 1.10 V and ECC enabled.
