Capacity and purpose

This 256 GB kit contains four 64 GB DDR5 ECC RDIMM modules built for the SuperMicro SYS-422GS-NBRT-LCC GPU SuperServer. It targets administrators expanding memory capacity in that specific platform.

Upgrade scope

The kit replaces smaller DDR5 RDIMM sets or fills empty slots to reach the 256 GB total. The jump is worthwhile when workloads need registered ECC memory at 6400 MHz with CL52 latency and 1.1 V operation.

Compatibility checks

Verify the motherboard accepts 288-pin DDR5 RDIMMs with 2Rx4 organisation and supports the PC5-51200 speed grade. Confirm the server BIOS recognises 64 GB registered modules and that the chassis has four free DIMM slots for the full kit.

Questions about this item

Will the 288-pin DDR5 RDIMM modules fit the SuperMicro SYS-422GS-NBRT-LCC server?

Yes, this kit is built for the SuperMicro SYS-422GS-NBRT-LCC and uses the standard 288-pin DDR5 RDIMM form factor that the system expects.

What is the correct way to populate the four 64 GB modules, and what step is often missed?

Install all four modules in the slots specified by the SuperMicro manual for 256 GB configurations, then enter the BIOS to confirm the 6400 MHz speed and CL52 latency are recognised.

When should the ECC RDIMM kit be replaced or serviced?

ECC RDIMMs have no moving parts and require no scheduled maintenance; replace a module only if the system logs correctable errors that exceed the platform threshold.
