Compatible Dell OptiPlex 7070 memory

This 16GB DDR4 DIMM is built for Dell OptiPlex 7070 Small Form Factor and Tower systems. It installs in a 288-pin slot and runs at 1.20V without ECC or buffering. The module suits users expanding a compatible workstation to 16GB per slot.

Sustained load behaviour

The stick operates at 2666MHz with CL19 timings of 19-19-19 across extended sessions. As a 2Rx8 unbuffered module, it delivers consistent throughput for typical office workloads. All installed memory will run at the speed of the slowest module or the processor limit.

Thermals noise and power

With no heat spreader and a low 1.20V operating voltage, the module generates minimal heat inside the chassis. Passive cooling from case airflow is sufficient for normal use. Power draw remains modest, keeping system acoustics unchanged during daily operation.

Questions about this item

How much heat and power does the 1.20 V DDR4 2666 module draw when the OptiPlex 7070 runs all day?

At the rated 1.20 V the stick draws only the standard DDR4 power envelope, so a typical OptiPlex 7070 SFF or Tower cooler handles the extra heat without fan-speed changes.

What must the OptiPlex 7070 already have — CPU, chipset and BIOS — for this 288-pin DIMM to be recognised?

Any Dell OptiPlex 7070 SFF or Tower that shipped with DDR4 slots will recognise the module; the board’s four 288-pin sockets and CPU memory controller manage the rest.

If I keep the original 8 GB sticks in the other three slots, will the 16 GB 2Rx8 module run at its rated CL19 2666 speed?

All installed memory runs at the slowest module’s speed; mixing ranks and capacities forces the system to the lowest common timing, so the new stick will drop to match the older modules.
