Dell OptiPlex 5060 and 5070 upgrade

This 8GB DDR4 module is built for Dell OptiPlex 5060 and 5070 systems in both small form factor and tower configurations. It delivers 2666MHz speed with CL19 timing at 1.2V. The unbuffered non-ECC design matches the factory specification for these platforms. Buyers who need ECC registered memory or capacities beyond 8GB per slot should look elsewhere.

Low voltage standard operation

Running at the standard 1.2V DDR4 voltage the stick draws minimal power and produces negligible heat. No heat spreader is fitted so airflow in the chassis handles cooling silently. The CL19 19-19-19 timings operate within JEDEC limits without extra voltage. Systems limited to lower memory speeds will downclock automatically.

Single stick lifetime replacement

The package contains one 288-pin DIMM manufactured by Computer Memory Solutions using major brand chipsets. The vendor provides a limited lifetime exchange or repair warranty against manufacturing defects when purchased directly. No software utilities or additional accessories are included. Builders populating the second slot must source a matching module separately.

Questions about this item

How do I install this 288-pin DDR4 DIMM in my OptiPlex 5060 SFF, and what step is often missed?

Power off and unplug the system, open the chassis, align the notch on the module with the slot key, press firmly until both retention clips click, then verify 2666 MHz speed in BIOS — many forget to seat both ends evenly.

What maintenance or replacement will this 8 GB CL19 module need over time?

No scheduled maintenance is required; the module carries a limited lifetime warranty against manufacturing defects, so replacement only occurs if a fault develops under normal use.

What limit appears first when this 1.2 V unbuffered kit runs sustained workloads on a two-slot board?

The platform caps total memory at 64 GB across its two slots, so capacity ceiling is reached before thermal or voltage limits become a factor.
