192 GB DDR5 server kit with twelve 16 GB registered ECC modules at 4800 MT/s CL40 for SuperMicro CloudDC systems
This 192GB kit contains twelve 16GB DDR5 4800 modules built for SuperMicro CloudDC SuperServer platforms. ECC registered RDIMM architecture delivers the data-integrity and signal-buffering that enterprise workloads demand. IT teams specify this memory when they need maximum capacity per channel on qualified motherboards. It targets administrators who run virtualization, database or HPC clusters on supported SuperMicro hardware.
Each 288-pin RDIMM operates at 1.1V and presents a single 1Rx8 rank, reducing electrical load on the memory controller. Registered buffering allows the platform to populate all twelve slots without exceeding drive-strength limits. The kit frees the builder from mixing capacities or speeds across channels. Buyers who need unbuffered UDIMMs or non-ECC memory for workstation boards cannot use this product.
The box supplies a full 12x16GB population ready for immediate installation in compatible SYS-621C-TN12R, SYS-611C-TN4R or SYS-121C-TN2R systems. Matched part number MR38400-618K12 eliminates the guesswork of sourcing identical sticks from separate lots. No heat spreaders are included, so airflow management follows the server chassis design. Customers requiring RGB lighting or desktop-oriented XMP profiles will not find them here.

The registered DDR5 modules run at 1.1V without heat spreaders; sustained loads rely on chassis airflow to keep temperatures within JEDEC limits.
Passive DDR5 RDIMMs add no fan noise; total power draw at 1.1V across 12 modules stays modest, so heat output depends on case ventilation.
The kit is validated for Supermicro CloudDC SuperServer SYS-621C-TN12R, SYS-611C-TN4R and SYS-121C-TN2R platforms.
