16GB DDR4-2133 Kit for OptiPlex 7040 Mini Tower

This 16GB kit contains two 8GB DDR4 DIMMs rated at 2133MHz with CL15 timings. It is built specifically for the Dell OptiPlex 7040 Mini Tower and uses unbuffered non-ECC memory. The modules run at 1.2V and install into the system's 288-pin slots.

Sustained workload stability

JEDEC-standard timings of 15-15-15 at 2133MHz keep latency predictable during long rendering or compilation sessions. The 2Rx8 organisation and major-brand chipset support consistent throughput without downclocking. Operation at the standard 1.2V helps maintain thermal headroom inside the compact Mini Tower chassis.

Plain DIMM build for dense layouts

Modules ship without heat spreaders, keeping the profile low for tight clearance between the CPU cooler and the four DIMM slots. The 288-pin unbuffered design matches the OptiPlex 7040 motherboard layout exactly. Buyers who want ECC error correction or registered buffering for server workloads should choose a different kit.

Questions about this item

How much power do the 1.2 V DDR4-2133 modules draw when the OptiPlex 7040 Mini Tower runs all day?

Each 8 GB stick operates at 1.2 V, the standard DDR4 voltage, so total draw stays low during continuous use.

What must the Dell OptiPlex 7040 Mini Tower already have for this 2 x 8 GB kit to work?

The system needs free 288-pin DDR4 DIMM slots; the OptiPlex 7040 Mini Tower provides four sockets supporting up to 64 GB.

Will these CL15 2133 MHz sticks run with any older DDR4 memory I keep in the other slots?

Yes, they are unbuffered non-ECC DDR4-2133 modules; the board will clock all installed sticks to the lowest common speed.
