Capacity 128GB (2 x 64GB)

  • 128 GB capacity handles heavy server workloads
  • ECC registered design corrects memory errors automatically
  • Dual-channel 2 x 64 GB kit maximises bandwidth
  • DDR4 2133 MHz speed matches PC4-17000 spec
  • 2 V operation keeps power draw low

Server memory upgrade kit

This 128GB kit contains two 64GB DDR4 modules built for servers and workstations that require registered ECC memory. Each module runs at 2133MHz with CL15 latency at the standard 1.20V. The kit is not compatible with desktop or laptop platforms.

Registered DIMM with 3DS stacking

The 288-pin RDIMM form factor uses octal-rank x4 3DS/TSV organisation to reach 64GB per module without a heat spreader. Registered buffering and on-die ECC protect data integrity in multi-module configurations. Dual-channel packaging simplifies population of matched memory channels.

Low-voltage DDR4 operation

At 1.20V the modules draw minimal power while delivering 2133MHz throughput. The absence of a heat spreader relies on chassis airflow for cooling; noise and thermals are therefore dictated by the server platform rather than the memory itself. CL15 timing supports responsive performance under sustained workloads.

Points forts

Questions sur cet article

What bandwidth does the PC4-17000 DDR4 2133 interface deliver in practice?

The PC4-17000 rating corresponds to a peak transfer rate of 17000 MB/s at 2133 MHz, which is the maximum throughput this DDR4 kit can sustain.

What physical slot and clearance does the 288-pin DDR4 RDIMM require?

Each 64 GB module uses a standard 288-pin DDR4 DIMM form factor and fits any server or workstation slot wired for registered ECC memory; no heat spreader is present, so low-profile clearance is not an issue.

How do I install the dual-channel kit and which step is commonly missed?

Insert both 64 GB modules into the correct paired slots for dual-channel operation, following the system manual’s channel guidelines; the step often missed is verifying that the platform supports 2S4Rx4 3DS/TSV octal-rank modules before purchase.
