256 GB ECC RDIMM kit for Supermicro GPU SuperServer

This 256 GB kit contains eight 32 GB DDR5 6400 MHz registered DIMMs built for the Supermicro SYS-422GS-NBRT-LCC. Each module runs at 1.1 V with CL52 latency and 2Rx8 organisation. The ECC registered design targets enterprise servers and workstations that require error correction and signal integrity.

Sustained load behaviour with registered DDR5

Registered buffering reduces electrical load on the memory controller during continuous operation. ECC corrects single-bit errors in real time, preventing data corruption during long compute runs. The 1.1 V operating voltage helps limit thermal output when all eight slots are populated at 6400 MHz.

Verify slot count and qualified vendor list

Confirm the Supermicro SYS-422GS-NBRT-LCC provides eight DDR5 RDIMM slots and that its qualified vendor list accepts 2Rx8 modules at 6400 MHz. Systems with fewer slots or a lower supported speed will not use the full capacity or frequency. Buyers who need non-registered UDIMMs or a different pin count should look elsewhere.

Questions about this item

How much power will the 256GB DDR5 6400MHz kit draw running all day in the SYS-422GS-NBRT-LCC?

Each 32GB module operates at 1.10V; total consumption depends on server load and the number of populated channels.

Does the SYS-422GS-NBRT-LCC need any specific BIOS setting or firmware revision before installing this 8x32GB CL52 kit?

The kit is validated for the Supermicro GPU SuperServer SYS-422GS-NBRT-LCC; consult the system manual for any required BIOS updates.

Can I keep my existing DDR5 RDIMMs and add this 256GB 2Rx8 kit alongside them in the same server?

Mixing ranks, capacities or speeds is not recommended; for best stability populate all eight slots with this matched 8x32GB kit.
