Server DDR4 ECC kit

This 128GB kit contains eight 16GB DDR4 2933 MHz ECC registered DIMMs built for servers and workstations that require registered memory. It is not compatible with desktop or laptop computers that use unbuffered modules.

288-pin registered build

Each module uses a 288-pin DIMM form factor with registered buffering and dual-rank x8 organisation to reduce electrical load on the memory controller. The 1.2V operating voltage matches standard DDR4 power requirements for stable operation in multi-module configurations.

Lifetime warranty and US support

A lifetime warranty covers the kit and United States based technical support is available before, during and after purchase. All modules undergo quality assurance testing to verify reliable performance in qualified systems.

Questions about this item

What bandwidth does the DDR4 2933 interface deliver and what speed does it cap at?

The DDR4 2933 interface is rated at PC4-23400, which caps the practical data rate at 2933 MT/s per module.

What physical slot and pin count does this 288-pin RDIMM need to fit?

Each 16 GB module uses the standard DDR4 DIMM form factor with 288 pins and requires a server or workstation motherboard slot keyed for registered memory.

How are the eight 2Rx8 modules installed and which seating step is often missed?

Install all eight modules in the correct channel order shown in the system manual, then press each DIMM down firmly until both side latches click — the latch click is the step most people skip.
