1TB DDR5 ECC RDIMM kit

This NEMIX RAM kit supplies 1 TB of registered DDR5 memory across eight 128 GB modules. It is built for Supermicro SuperServer SYS-822GS-NB3RT systems that require ECC RDIMM memory. The modules run at 6400 MHz with CL52 latency at 1.1 V.

Replaces slower or smaller DDR5 RDIMM sets

The jump is worth it when the workload demands maximum registered ECC capacity at the platform's rated 6400 MHz speed. Each 2Rx4 module uses major OEM chips from Samsung Micron or Hynix and operates at the standard 1.10 V.

Suits administrators scaling Supermicro

Builders needing unbuffered DIMMs or non-ECC memory should look elsewhere. Systems that cannot accept 288-pin registered DDR5 modules or that require lower-density sticks are not compatible with this kit.

Questions about this item

Will the 288-pin DDR5 RDIMM modules fit the SuperMicro SuperServer SYS-822GS-NB3RT memory slots?

Yes, the kit is built as a 288-pin DDR5 RDIMM form factor that matches the SuperMicro SuperServer SYS-822GS-NB3RT memory slots exactly.

What is the correct order for populating the eight 128GB modules across the server's memory channels?

Follow the SuperMicro SuperServer SYS-822GS-NB3RT manual channel population guide; install modules in the prescribed slot sequence per CPU so each channel receives identical 2Rx4 RDIMMs.

When should the registered ECC RDIMMs be reseated or replaced to maintain error-correction reliability?

Reseat the 2Rx4 modules if the system logs corrected ECC errors or after any chassis service; replace a module only when uncorrectable errors persist or a DIMM fails POST.
