Computer Memory Solutions 16GB (2x8GB) DDR4 2666 CL19 288-pin DIMM D22

16 GB DDR4 kit for Dell Precision workstations

This 16 GB kit contains two 8 GB DDR4 modules rated at 2666 MHz with CL19 timing. The unbuffered non-ECC DIMMs operate at 1.2 V and use a 288-pin layout. They are built to run in Dell Precision 3430 Small Form Factor, Precision 3431 Desktop and Precision 3630 Tower systems.

Who this suits and who should look elsewhere

The kit suits owners of the listed Precision models who need a matched pair of 8 GB sticks for standard workloads. It is not for buyers who require ECC error correction, registered modules, speeds above 2666 MHz, capacities beyond 16 GB per kit, or compatibility with platforms outside the three Dell models named.

2666 MHz DDR4 speed with CL19 latency

The decisive specification is the DDR4 2666 (PC4 21300) rating combined with CL19 19-19-19 timing. Faster memory will clock down to this speed depending on the installed processor, so this kit delivers the exact frequency and latency the supported systems are designed to use.
