Two green DDR5 RDIMM sticks without heat spreaders

NEMIX RAM

NEMIX RAM 256GB (2x128GB) DDR5 6400MHz PC5-51200 4Rx4 1.1V 288-PIN ECC RDIMM Registered Server Memory Kit

SKU CH-YM7T-AA7E5

256 GB kit of two 128 GB DDR5 6400 MHz ECC registered DIMMs validated for Supermicro X14SBI-TF servers

  • Capacity256GB (2 x 128GB)
  • ECCYes
  • Buffered/RegisteredRegistered
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • Voltage1.10V
  • Compatible SystemSupermicro
  • 256GB total capacity supports large datasets with two 128GB modules
  • DDR5 6400MHz speed delivers high bandwidth for demanding workloads
  • ECC registered design protects data integrity in mission-critical systems
  • 1V operation reduces power draw per module
  • Validated for Supermicro X14SBI-TF compatibility ensures reliable integration

Capacity and platform fit

This 256GB kit delivers two 128GB DDR5 RDIMM modules built for Supermicro X14SBI-TF systems. Registered ECC operation and 4Rx4 organisation suit multi-socket servers and memory-intensive workloads that require error correction and high density per slot.

Speed ceiling and voltage headroom

Rated at 6400MHz PC5-51200 with CL52 latency, the modules run at 1.10V standard DDR5 voltage. The registered buffer adds one cycle of command latency, so peak bandwidth is reached on sustained server loads rather than bursty desktop patterns.

Upgrade path and limits

The kit replaces lower-capacity RDIMM sets or fills empty slots on X14SBI-TF boards that support 128GB per DIMM. It will not work in unbuffered UDIMM slots, non-ECC consumer platforms, or systems limited to 64GB modules.

Domande su questo articolo

Can these DDR5 6400MHz RDIMMs run with slower DDR5 modules already in my Supermicro X14SBI-TF?

Mixing speeds forces all modules to the slowest installed kit; the 6400MHz rating will drop to match the lower frequency.

How can I confirm the 256GB kit is running at 6400MHz with ECC active after installation?

Check BIOS or UEFI memory info for 6400MHz speed, CL52 latency, 1.10V voltage and ECC enabled status.

What exactly ships in the box and do I need extra cooling or cables?

The box contains two 128GB DDR5 RDIMMs; no heat spreaders, cables or additional parts are included.
