NEMIX RAM

NEMIX RAM 8GB DDR4 2666MHz PC4-21300 CL19 288-Pin UDIMM HPE Compatible memory upgrade

SKU CH-J2ST-XBTV1

An 8 GB DDR4-2666 UDIMM built for HPE systems with CL19 timing and 1.2 V operation

  • Capacity8GB
  • SpeedDDR4 2666 (PC4 21300)
  • ECCNo
  • Buffered/RegisteredUnbuffered
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • Voltage1.20V
  • 8GB capacity expands system memory for heavier workloads
  • DDR4 2666MHz speed delivers responsive desktop performance
  • CL19 latency supports stable operation under load
  • 2V low-voltage design reduces power draw and heat
  • 288-pin UDIMM form factor fits compatible HPE systems

HPE-Compatible DDR4 UDIMM

This 8GB DDR4 2666MHz module is built for HPE servers and workstations that accept unbuffered non-ECC UDIMMs. It suits administrators upgrading compatible HPE platforms such as the 879505-B21 part number.

PC4-21300 speed ceiling

The DDR4 2666 standard caps transfer rates at PC4-21300 with CL19 latency at 1.2V. Systems that only support lower DDR4 speeds will clock the module down, and boards requiring registered or ECC memory cannot use this stick.

Verify slot type and rank support

Confirm the motherboard accepts 288-pin unbuffered non-ECC UDIMMs and can address a single-rank 1Rx8 module. Check the system manual for maximum per-slot capacity and total memory limit before ordering.

Questions sur cet article

Is the single 8GB module sufficient or should I add a second 8GB stick for dual-channel?

The module is sold as 1x8GB; adding a second identical stick enables dual-channel on boards that support it.

What does PC4-21300 mean for actual throughput in my HPE system?

PC4-21300 rates the module at 21300 MB/s peak bandwidth; real-world throughput depends on the memory controller and workload.

Does the 288-pin DDR4 UDIMM interface limit speed to 2666MHz on my motherboard?

The module runs at 2666MHz; the board's memory controller will set the final speed, which cannot exceed the module's rated 2666MHz.
