Dell OptiPlex 7060 memory kit

This 64GB kit contains four 16GB DDR4 DIMMs rated at 2666MHz with CL19 timings. It is built for Dell OptiPlex 7060 SFF, Tower and OptiPlex XE3 Tower systems that accept standard 288-pin unbuffered memory.

Four-slot upgrade path

The kit fills all four memory sockets on the supported OptiPlex platforms, delivering the maximum 64GB capacity those boards allow. Each module runs at 1.2V and uses a 2Rx8 organisation, so the CPU memory controller sees a consistent load across every channel.

Matched modules from one supplier

Computer Memory Solutions packages the four sticks as a single kit to avoid timing mismatches that can occur when mixing loose modules. The maker states that all parts are manufactured in-house rather than sourced from generic stock, and they provide a lifetime exchange or repair warranty against manufacturing defects.

Questions about this item

Does the CL19 latency and 1.20V voltage limit how far the DDR4 2666 speed scales under sustained load?

The kit is rated for CL19 at 1.20V, so the modules run at DDR4 2666 within standard JEDEC limits; sustained workloads stay at that speed and voltage unless the platform applies a lower multiplier.

How much heat do four unbuffered 2Rx8 DIMMs produce when running all day in a Dell OptiPlex 7060 SFF?

Each 16GB stick operates at 1.20V without a heat spreader; typical DDR4 power at this voltage is low, so case airflow in the OptiPlex 7060 SFF or Tower is usually sufficient for continuous operation.

Must the OptiPlex 7060 or XE3 Tower already have four free 288-pin slots and a CPU that supports DDR4 2666?

Yes — the kit fills all four DIMM sockets (4 × 16GB) and requires a processor and chipset that run DDR4 at 2666MHz; the listed OptiPlex 7060 SFF, 7060 Tower and XE3 Tower meet that requirement.
