Dell G5 5090 and Inspiron 5680 Memory

This 16 GB DDR4 DIMM is built for the Dell G5 Gaming Desktop 5090 and the Inspiron 5680 Desktop. It adds a single 16 GB module running at 2666 MHz with CL19 timings. The unbuffered, non-ECC design matches the factory specification for these systems. Buyers who need ECC error correction or registered modules cannot use this kit.

Installation and Common Issues

The 288-pin DIMM seats in a standard DDR4 slot at 1.2 V. Alignment is keyed, so the module fits one way only. Most issues come from mixing this stick with older modules that run at different speeds or latencies, which can force the system to downclock or fail to boot. The board supports up to 64 GB across four sockets, so a single 16 GB stick leaves room for expansion.

Sustained Load Behaviour

Under continuous workloads the module operates at its rated 2666 MHz with 19-19-19 timings and 1.2 V. No heat spreader is fitted, so case airflow must carry heat away from the chips. The major-brand chipset and unbuffered layout keep signal integrity stable during long sessions. Systems limited to lower memory speeds will run this module at the lower frequency automatically.

Questions about this item

How can I confirm the 16GB DDR4 2666MHz module is running at the correct speed after installing it in my Dell G5 5090?

Enter the BIOS or use a tool like CPU-Z to verify the memory reports 2666MHz and CL19-19-19 timings at 1.2V; the system should also show 16GB total capacity for the installed stick.

What exactly is included in the package, and do I need any extra parts to install this 288-pin DIMM?

The box contains one 16GB 288-pin DDR4 DIMM; no additional cables, brackets or heat spreaders are required — just an empty DDR4 slot on the motherboard.

My Dell Inspiron 5680 has four slots and supports up to 64GB — should I buy one 16GB stick or two for dual-channel performance?

Adding a single 16GB module works immediately; installing a second identical stick later will enable dual-channel mode, so choose based on whether you want maximum bandwidth now or prefer to spread the cost.
