512 GB DDR5 ECC RDIMM kit

This NEMIX RAM kit delivers 512 GB of DDR5 4800 memory in four 128 GB registered DIMMs. Each module operates at 1.1 V with CL40 latency and uses a 4Rx4 organisation. The 288-pin RDIMMs include ECC for error correction in server workloads. The kit is validated for Supermicro CloudDC SuperServer SYS-621C-TN12R, SYS-611C-TN4R and SYS-121C-TN2R systems.

Suited for Supermicro DDR5 servers needing maximum

Administrators expanding memory in the listed Supermicro CloudDC platforms can install this 512 GB kit to reach the highest supported density per channel. The registered design and ECC function maintain signal integrity and data accuracy under sustained load. Builders targeting consumer motherboards, workstations without registered DIMM support, or systems limited to lower-density modules should select a different memory type.

Four 128 GB 4Rx4 modules at DDR5 4800 CL40

The 4Rx4 rank structure on each 128 GB DIMM determines how the memory controller addresses the array and affects maximum population rules. This organisation, combined with the 4800 MT/s speed and CL40 timing, is the critical specification for compatibility with the qualified Supermicro platforms. Verifying that the server memory controller supports 4Rx4 RDIMMs at this speed ensures the kit will function as intended.

商品問答

Will these 4Rx4 DDR5 4800 CL40 RDIMMs run with existing DDR5 4800 modules already in my Supermicro CloudDC SYS-621C-TN12R?

Yes, they share the same DDR5 4800 speed, 1.1 V voltage, CL40 latency and 288-pin RDIMM form factor, so the memory controller will train them together at 4800 MT/s.

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

Enter the BIOS or use a tool like dmidecode; you should see 512 GB total, 4800 MT/s data rate, CL40 timings, 1.1 V and ECC status reported as enabled for each of the four 128 GB modules.

Does the MR38400-744K4 kit include heat spreaders or any extra cables I need to buy?

The package contains only the four 128 GB 288-pin DDR5 RDIMM modules; no heat spreaders, cables or mounting hardware are included.
