Compatible Dell Vostro upgrade

This 8 GB DDR4 module is built for the Vostro 3470 Small Desktop, Vostro 3670 and Vostro 3671. It installs as a single 288-pin DIMM and uses unbuffered non-ECC chips. The part targets owners of those specific Dell systems who need a straightforward capacity increase.

Sustained operation at 2666 MHz

The stick runs at 2666 MHz with CL19 timings and a standard 1.2 V supply. Because it has no heat spreader, thermal performance depends on the chassis airflow of the supported Vostro models. Under continuous load the memory will operate at the slowest speed present in the system, so adding a slower module would reduce overall throughput.

Two-slot 32 GB ceiling

The supported platforms provide two DIMM sockets and a maximum of 32 GB total capacity. A single 8 GB module leaves one slot free for a future matched pair, but buyers who want more than 32 GB or who need ECC registered memory must choose a different platform.

Questions about this item

How much heat or power does the 1.20V DDR4-2666 module add when the Vostro 3470 runs all day?

The module runs at the standard 1.20V DDR4 voltage with no heat spreader, so its thermal contribution inside the Vostro 3470 small desktop is minimal during continuous use.

What must the Dell Vostro 3670 already have — BIOS version, CPU generation or empty DIMM slot — for this 288-pin stick to work?

The Vostro 3670 needs a free 288-pin DDR4 slot and a 64-bit operating system; the board supports up to 32 GB across its two sockets.

Will this CL19 2Rx8 stick slow down if I keep the original memory in the Vostro 3671?

Yes — all installed modules run at the speed of the slowest stick or the CPU limit, so mixing with slower original memory reduces overall performance.
