SuperMicro DDR5 ECC RDIMM Kit

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.

1.1V registered modules for dense server builds

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.

Twelve matched modules in one package

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.

Questions about this item

What thermal limit does the 12-module DDR5 4800 kit hit during continuous server workloads?

The registered DDR5 modules run at 1.1V without heat spreaders; sustained loads rely on chassis airflow to keep temperatures within JEDEC limits.

How much noise and heat does the 192GB DDR5 4800 kit produce when running all day?

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.

Which Supermicro server models must I already own for this 12x16GB DDR5 4800 kit to work?

The kit is validated for Supermicro CloudDC SuperServer SYS-621C-TN12R, SYS-611C-TN4R and SYS-121C-TN2R platforms.
