Eight green DDR5 RDIMM modules in a row

NEMIX RAM

NEMIX RAM 1TB (8x128GB) DDR5 4800 PC5-38400 CL40 288-Pin ECC RDIMM SuperMicro Server memory upgrade

SKU CH-7R2B-0VWH2

Eight 128 GB DDR5 modules deliver 1 TB of ECC registered memory at 4800 MT/s for compatible SuperMicro servers

  • Compatible with SuperMicro SYS-211SE and X31SEED platforms

1 TB DDR5 ECC RDIMM kit

This 1 TB memory kit contains eight 128 GB registered DDR5 modules running at 4800 MT/s with CL40 latency. It is built for SuperMicro IoT SuperServer systems such as the SYS-211SE-31DS, SYS-211SE-31AS and X31SEED-SF motherboards that require ECC RDIMM memory.

Upgrade from lower-capacity DDR5 RDIMMs

Replacing smaller DDR5 RDIMMs with this 8-module kit raises total capacity to 1 TB while keeping the same 4800 MT/s speed and 1.10 V voltage. The jump is worthwhile when workloads need more simultaneous threads or larger in-memory datasets than the current configuration allows.

Suited for SuperMicro servers needing maximum

This kit fits administrators expanding SuperMicro IoT SuperServer platforms that support 4Rx4 registered DDR5 modules. Buyers who need unbuffered memory, non-ECC modules, or a different form factor should look elsewhere.

Questions about this item

Does this 288-pin DDR5 RDIMM kit fit the SuperMicro IoT SuperServer SYS-211SE-31DS and SYS-211SE-31AS models?

Yes, the kit is validated for the SuperMicro IoT SuperServer SYS-211SE-31DS, SYS-211SE-31AS and X31SEED-SF motherboard, using the standard 288-pin DDR5 RDIMM form factor.

What is the correct way to populate all eight 128 GB modules on a SuperMicro DDR5 server board?

Follow the motherboard manual’s channel population order; a common mistake is skipping the first slot in each channel, which prevents the registered ECC modules from initialising at 4800 MT/s.

Will the Samsung, Micron or Hynix DRAM chips on these registered ECC modules need any firmware updates or periodic replacement?

No firmware updates are required for the DRAM; the modules are stress-tested at 1.10 V and CL40, and the registered ECC design is rated for continuous server operation without scheduled replacement.
