192GB DDR5 ECC RDIMM kit for Supermicro servers

This 12-module kit delivers 192GB of DDR5 4800 registered ECC memory built for Supermicro Hyper SuperServer platforms. Each 16GB stick runs at 1.1V with CL40 latency and a 1Rx8 organisation. The modules are 288-pin RDIMMs without heat spreaders, validated for 24/7 server workloads.

Verify motherboard slot count

Your Supermicro system must provide twelve DDR5 RDIMM slots and accept registered ECC modules at 4800 MT/s. Confirm the platform BIOS recognises 1Rx8 density and 1.1V operation. Registered DIMMs will not function in desktop or unbuffered-only boards, so the server chassis and motherboard must explicitly support this form factor.

Kit format simplifies large-capacity deployment

The twelve matched modules ship together as a single 192GB package, eliminating the need to source individual sticks and reducing the risk of mixed revisions. No additional software, cables or cooling accessories are included; installation follows the server vendor's standard memory population rules.

Questions about this item

Does the 192GB kit ship as 12 individual 16GB modules or must I order them separately?

The kit contains 12 modules of 16GB each, giving 192GB total in one package.

Why choose the CL40 4800MHz version instead of a lower-latency kit?

CL40 at 4800MHz is the JEDEC base speed for DDR5 ECC RDIMM; it guarantees stability on Supermicro SYS-121H-TNR, SYS-221H-TNR and SYS-221H-TN24R without manual tuning.

What does the 1Rx8 organisation mean when the modules are installed in a Supermicro server?

Each 16GB module uses a single rank of x8 chips, so the memory controller sees twelve ranks across the kit, which matches the supported population rules for the listed Supermicro Hyper SuperServer models.
