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.

Questions about this item

What does DDR4 2666 (PC4 21300) mean for real-world bandwidth?

The modules run at 2666 MT/s with CL19 timing; the system will clock them down if the installed processor only supports a lower speed.

Will these 288-pin DIMMs fit the Dell Precision 3430 Small Form Factor?

Yes, the kit is validated for Precision 3430 SFF, 3431 Desktop and 3630 Tower, all of which use standard 288-pin DDR4 slots.

How do I install the two 8 GB sticks correctly?

Power off, open the case, align each module notch with the slot key, press firmly until the retention clips click; populate the slots recommended in the Dell service manual for dual-channel operation.
