Server DDR4-2666 ECC Registered DIMM

This 16 GB DDR4-2666 module is built for servers and workstations that require error-correcting registered memory. It targets administrators expanding capacity in systems qualified for PC4-21300 speeds. The registered design reduces electrical load on the memory controller for stable operation.

Capacity and headroom at 16 GB CL19

A single 16 GB rank handles growing databases, additional virtual machines and larger application datasets. The CL19 timing at 2666 MHz delivers consistent throughput for memory-bound workloads. Headroom ends when the platform reaches its maximum DIMM slots or total memory limit.

288-pin registered fit for qualified platforms

The 288-pin DIMM installs only in DDR4 slots that support registered ECC operation at 1.20 V. It requires a server or workstation motherboard validated for registered modules. The lack of a heat spreader keeps the profile low for dense chassis configurations.

商品問答

Will this 16 GB DDR4-2666 CL19 registered module work alongside my existing DDR4 registered ECC DIMMs?

This module runs at DDR4-2666 with CL19 timing and 1.20 V. When mixed with other registered ECC DIMMs, the system will operate at the speed of the slowest installed module.

How can I verify the 2666 MHz speed and CL19 latency are active after installation?

Check the memory speed and CAS latency reported in your server BIOS or UEFI, or use a tool such as CPU-Z or dmidecode to confirm 2666 MT/s and 19-19-19 timings.

Does the box include only the 288-pin DIMM or are any cables or brackets supplied?

The package contains the single 16 GB 288-pin DDR4 registered ECC DIMM. No cables, brackets or additional accessories are included.
