Capacity and fit

This 16GB DDR4 module uses a 288-pin DIMM form factor and runs at 2666MHz with CL19 timing. It is validated for Dell OptiPlex 3070 SFF and Tower systems as well as Dell G5 5090 and Inspiron 5680 desktops. The stick is unbuffered, non-ECC and operates at 1.2V.

Build integration

A single 16GB stick occupies one of the two available DIMM slots and leaves the second slot open for a matching module. The system maximum is 32GB, so adding a second identical stick completes the supported capacity. No heat spreader is fitted, keeping the profile low for small-form-factor chassis.

Sustained operation

The module uses major-brand chips rated for continuous operation at the specified 1.2V. Unbuffered topology and 2Rx8 organisation deliver stable throughput during extended workloads without registered-buffer overhead. Lifetime repair or exchange coverage from the manufacturer applies to manufacturing defects.

Questions about this item

How far can I expand the Dell OptiPlex 3070 Tower beyond this 16 GB module?

The platform supports a maximum of 32 GB across its two DIMM sockets, so adding a second 16 GB stick reaches the limit.

What thermal and acoustic impact should I expect when the module runs continuously at 1.2 V?

With no heat spreader and standard JEDEC voltage, the stick adds minimal heat and produces no audible noise inside the OptiPlex 3070 chassis.

Which motherboard slot and chipset combination is required for this 288-pin DDR4 DIMM to function?

It installs in a standard DDR4 DIMM socket on Intel 300-series chipset boards such as those in the OptiPlex 3070 SFF, 3070 Tower, G5 5090 or Inspiron 5680.
