Dell OptiPlex 3060 3070 5060 DDR4 Upgrade

This 8GB DDR4 2666MHz CL19 UDIMM is built for Dell OptiPlex 3060 SFF, 3060 Tower, 3070 SFF, 3070 Tower and 5060 SFF desktops. It suits users who need a straightforward capacity increase for daily multitasking on these specific platforms. The module runs at 1.2V and uses a 288-pin unbuffered non-ECC design.

JEDEC Compliant Standard Module

The stick meets JEDEC PC4-21300 specifications and is ROHS compliant, ensuring a warranty-safe upgrade without configuration changes. It installs as a standard DIMM with no heat spreader, extra software or proprietary tools required. Backward compatibility with 2133MHz and 2400MHz systems allows it to downclock automatically when installed in slower slots.

DDR4 2666MHz Interface Limits

The DDR4 2666MHz interface caps bandwidth at the PC4-21300 rate, so workloads needing higher throughput will not benefit from faster memory. CL19 latency is fixed by the JEDEC standard and cannot be tightened on these OptiPlex platforms. Systems limited to 2133MHz or 2400MHz will run this module at the lower speed. Builders needing ECC error correction or registered signal buffering must choose a different module type.

Questions about this item

Will the 1Rx8 single-rank design need any special handling when I add more sticks later?

The module is a standard 1Rx8 DDR4 UDIMM; just match speed and voltage when expanding and the system will recognise it automatically.

Does the CL19 latency at 2666 MHz become a bottleneck during long rendering sessions?

CL19 at 2666 MHz is the rated timing; sustained workloads run at this latency unless the platform downclocks to 2400 MHz or 2133 MHz.

How warm does the bare 288-pin UDIMM get when the OptiPlex runs all day?

Without a heat spreader the stick relies on case airflow; at 1.2 V typical DDR4 thermals stay well within JEDEC limits in a ventilated chassis.
