Dell OptiPlex and Inspiron upgrade kit

This 8 GB kit contains two 4 GB DDR4 DIMMs rated at 2400 MHz with CL17 timings and 1.2 V operation. It is built for the Dell Inspiron 3268, OptiPlex 5050 SFF or Tower and OptiPlex 7040 Mini Tower where the board accepts unbuffered non‑ECC memory.

Thermals and power in daily use

The modules run at the standard 1.2 V without a heat spreader, so they add minimal heat inside compact Dell chassis. Normal office workloads keep temperatures low and the system fans remain quiet because the memory draws only its rated voltage.

What the bundle changes

Two matched sticks enable dual‑channel bandwidth on the four‑slot motherboards found in these models, raising usable throughput over a single module. The kit fills half the slots and leaves room to reach the 64 GB maximum later. Computer Memory Solutions backs the parts with a limited lifetime warranty against manufacturing defects.

Questions about this item

How do I install the 288-pin DDR4 DIMMs in my OptiPlex 5050, and which step is often missed?

Power off and unplug the PC, open the case, align each module notch with the slot key, press firmly until both side clips click, then verify the 2400 MHz speed in BIOS.

What maintenance or replacement will this 1.2 V unbuffered kit need later?

No scheduled maintenance is required; if a module fails, the manufacturer offers a lifetime exchange against manufacturing defects.

What limit appears first when the CL17 2Rx8 sticks run sustained workloads?

The DDR4 2400 MT/s data rate and CL17 latency set the throughput ceiling before thermal throttling becomes a factor.
