Targeted Dell Vostro Upgrade

This 32GB kit contains two 16GB DDR4 DIMMs rated at 2666MHz with CL19 timing and 1.20V operation. It is built for Dell Vostro 3470 Small Desktop, 3670 and 3671 systems that accept 288-pin unbuffered non-ECC memory. The modules use major-brand chips in a 2Rx8 configuration without heat spreaders.

Replacing Slower or Smaller Kits

The upgrade replaces factory-installed modules running at lower speeds or capacities below the 32GB maximum these models support. A jump is worthwhile when the CPU and chipset can address the full 32GB and the board has two slots available for the matched pair. All installed memory will run at the speed of the slowest module present.

Check Slots and OS Before Ordering

Verify that your Vostro has two free 288-pin DIMM sockets and that a 64-bit operating system is installed to use more than 4GB. The system maxes out at 32GB across two slots, so any existing memory must be removed to fit this kit. Mixing with other modules will force the whole array to the slowest timing.

Questions about this item

Will the 288-pin DDR4 DIMMs fit the two memory slots in my Dell Vostro 3470 Small Desktop?

Yes, the kit is built for the Vostro 3470 Small Desktop, Vostro 3670 and Vostro 3671, each of which has two 288-pin DDR4 slots that accept these unbuffered non-ECC modules.

What is the correct way to seat the two 16 GB sticks so the system runs at 2666 MHz CL19?

Power off, open the case, align each module's notch with the slot key, press firmly until both side clips click, then boot; the matched pair will run at the rated 2666 MHz CL19 timing.

Do these modules need any cleaning or replacement during the life of the Dell Vostro 3670?

No routine maintenance is required; the sticks carry a limited lifetime warranty from Computer Memory Solutions and should last the usable life of the Vostro 3670 unless a manufacturing defect appears.
