64GB DDR4 2666 kit for OptiPlex desktops

This 64GB kit contains two 32GB UDIMM modules rated at 2666 MT/s with CL19 latency and 1.20V operation. It is built for Dell OptiPlex SFF and Tower models including the 3050, 3060, 3070, 5050, 5060, 5070, 7050, 7060 and 7070.

Steady throughput at 1.20V across long sessions

The modules run at the standard 1.20V, keeping power draw low during extended workloads. DDR4 bandwidth supports sustained multitasking without the voltage spikes that can throttle performance on lesser kits.

Direct 288-pin fit with no extra configuration

Each stick uses the 288-pin UDIMM form factor and drops into the supported OptiPlex boards without BIOS changes. Builders who need ECC or registered memory will find this unbuffered non-ECC kit unsuitable.

Perguntas sobre este artigo

How much heat and power does the 1.20 V DDR4 2666 kit produce when running all day?

It operates at 1.20 V, consuming 20 % less voltage for an overall power reduction of up to 40 %, so heat and electricity draw stay low.

What must my motherboard provide for these two 32 GB UDIMMs to work?

A desktop board with two free 288-pin DDR4 slots that accept 1.20 V, CL19 modules at 2666 MT/s.

Will the CL19 2666 sticks run stably alongside the original memory in my OptiPlex 7050 tower?

The kit is validated for OptiPlex 7050 towers and will down-clock to match any slower DDR4 already installed, keeping the system stable.
