Targeted upgrade for Dell Vostro

This 16GB DDR4 module is built specifically for Dell Vostro 3470 Small Desktop, Vostro 3670 and Vostro 3671 systems. It installs as a single 288-pin DIMM running at 2666MHz with CL19 timing and 1.20V operation. The unbuffered, non-ECC design matches the factory specification for these platforms.

Best for single-slot capacity boost

The stick suits owners who want to reach the 32GB ceiling using only one of the two available slots, leaving the second free for a matching module later. Builders needing ECC, registered memory, lower voltage or a different pin count should look elsewhere, as this unit is strictly non-ECC unbuffered DDR4.

Fits two-slot Vostro motherboards

The module plugs directly into the standard DDR4 DIMM sockets on the supported Vostro boards and runs at the rated 2666MHz speed without manual configuration. Pairing it with an identical stick enables dual-channel bandwidth, while the single-rank-per-channel layout keeps the memory controller load light for stable operation.

Questions about this item

Does my Dell Vostro 3470 Small Desktop need a free 288-pin DIMM slot to use this 16GB module?

Yes, the Dell Vostro 3470 Small Desktop has two DIMM sockets and this stick occupies one 288-pin DDR4 slot.

Will this CL19 2666MHz stick slow down if I keep my existing slower DDR4 modules installed?

All memory in the system will run at the slowest installed module speed or the CPU capability, so mixing can reduce the 2666MHz rate.

How can I confirm the 16GB stick is detected at 2666MHz after I install it?

Check the BIOS memory information or Windows Task Manager Performance tab to verify 16GB total capacity and 2666MHz speed.
