System-Specific DDR4 Kit for OptiPlex 5060 and 5070

This 16 GB kit contains two 8 GB unbuffered DIMMs built for Dell OptiPlex 5060 and 5070 systems in both small form factor and tower chassis. It delivers 2666 MHz DDR4 speed with CL19 timing at 1.2 V. The modules use major-brand chips and carry no heat spreader.

Verify Slot Count and Maximum Capacity Before

The supported platforms provide two DIMM sockets and a 64 GB ceiling, so this pair fills every slot. Confirm your motherboard revision matches the listed OptiPlex models and that the BIOS recognises non-ECC unbuffered DDR4. Buyers needing more than two modules or ECC functionality cannot use this kit.

Steady Operation at Rated Frequency Without Active

Running continuously at 2666 MHz and 1.2 V, the unbuffered 2Rx8 modules rely on case airflow rather than a spreader. Sustained workloads keep the sticks at standard JEDEC thermal limits because the voltage and density remain modest. Systems with restricted internal airflow should still ensure adequate circulation across the memory area.

Questions about this item

Does the box contain anything besides the two 8 GB sticks?

The package contains only the two 288‑pin DDR4 modules; no heat spreaders, cables or tools are included.

Should I choose the 16 GB kit or a single 8 GB module for my OptiPlex 5060?

The OptiPlex 5060 has two slots and supports up to 64 GB, so the 2 × 8 GB kit fills both slots and leaves room for future upgrades.

Will the CL19 timing at 2666 MHz slow down everyday tasks on a 5070 Tower?

At 1.2 V the modules run at the standard 2666 MT/s rate; CL19 is the native latency for this speed and will not create a noticeable bottleneck in typical office workloads.
