Targeted Dell OptiPlex upgrade

This 4 GB DDR4 SODIMM is built for Dell OptiPlex 3060 Micro, 5060 Micro, 5260 All-in-One and 7060 Micro systems. It installs in a single 260-pin slot and runs at 1.2 V without ECC or buffering. The module suits owners who need a straightforward capacity increase on these specific platforms.

Steady throughput with CL19 timing

Rated at 2666 MHz (PC4-21300) with 19-19-19 latency, the stick delivers consistent bandwidth during extended workloads rather than only in brief bursts. Unbuffered, single-rank organisation keeps signal paths short, helping maintain stable operation when the system runs memory-intensive tasks for long periods.

DDR4 SO-DIMM ceiling at 32 GB total

The supported OptiPlex models accept a maximum of 32 GB across two sockets, so this 4 GB module leaves room for one more stick. Builders who need more than 32 GB or who require ECC or registered memory must choose a different platform, as the DDR4 SO-DIMM interface here does not support those configurations.

Questions about this item

How much power does the 1.2 V DDR4 2666 MHz SODIMM draw when the OptiPlex 7060 Micro runs continuously?

At the standard 1.2 V the module draws very little power, so heat and fan noise stay low even during all-day operation in the Micro chassis.

Which slot type must the Dell OptiPlex 5060 Micro already have for this 260-pin stick to fit?

The system needs a DDR4 SO-DIMM slot; the 260-pin keying matches the OptiPlex 5060 Micro memory socket exactly.

Can the 4 GB CL19 module be paired with the factory memory to reach the 32 GB two-socket limit of the OptiPlex 5260 All-in-One?

Yes, the stick is unbuffered non-ECC DDR4 2666 MHz, matching the platform specs, so it works alongside the original module up to the 32 GB maximum.
