128 GB DDR5 ECC RDIMM for Supermicro SYS-422GS

This registered DIMM targets the Supermicro GPU SuperServer SYS-422GS-NBRT-LCC. It delivers 128 GB of DDR5 memory in a single module. The ECC and registered design suits workloads that require data integrity and signal stability. Buyers needing non-ECC or unbuffered memory for desktop platforms cannot use this module.

CL52 latency at 6400 MHz with 1.1 V operation

The module runs at 6400 MHz (PC5-51200) with a CAS latency of 52 cycles. Two-rank 2Rx4 organisation provides density without exceeding the single-slot footprint. Voltage is set to 1.1 V. Workloads that demand lower latency or higher clock speeds will exceed this module's rated timing envelope.

288-pin registered form factor requires compatible

The 288-pin DDR5 RDIMM fits server boards wired for registered ECC memory. No heat spreader is fitted, so airflow across the PCB must be provided by the chassis. Systems that accept only UDIMM or SO-DIMM modules cannot accommodate this part.

Questions about this item

Will this 6400MHz DDR5 RDIMM run with slower DDR5 modules already installed in my SYS-422GS-NBRT-LCC?

The server will clock all modules to the speed of the slowest installed DDR5 RDIMM, so this 6400MHz stick will downclock to match existing slower memory.

How can I verify the module is running at 6400MHz CL52 after installation?

Check the BIOS memory information or use a tool such as dmidecode to confirm the reported speed is 6400MHz and the CAS latency shows CL52.

Does the package include a heat spreader or any mounting hardware for the SYS-422GS-NBRT-LCC?

The module ships without a heat spreader and no extra mounting hardware is included; only the single 128GB 288-pin DDR5 RDIMM is in the box.
