System-Specific DDR4 Kit

This 16 GB kit delivers two 8 GB DIMMs built for Dell G5 5090 and Inspiron 5680 desktops. It runs at 2666 MHz with CL19 timing at 1.2 V, using unbuffered non-ECC DDR4 chips on a 288-pin interface. The modules are validated for those platforms so they install without compatibility guesswork.

Upgrade from 8 GB or slower DDR4

The kit replaces a single 8 GB stick or slower memory to reach the platform maximum of 32 GB across two slots. The jump is worth it when multitasking, gaming or content workloads exceed the capacity or bandwidth of the original configuration. Builders needing more than two slots or ECC support should look elsewhere.

Steady throughput under load

Unbuffered DDR4 at 1.2 V maintains the rated 2666 MHz transfer rate during extended sessions without thermal throttling. The 19-19-19 timings stay consistent across sustained reads and writes, keeping frame-times smooth and compile jobs predictable. No heat spreader is fitted, so case airflow handles the thermal load.

Questions about this item

Will the 288-pin DDR4 DIMMs fit the two slots inside my Dell G5 5090?

Yes, the kit matches the 288-pin DDR4 DIMM form factor used by the G5 5090 and Inspiron 5680, and the system has two slots for the two 8 GB modules.

Do I need to enable XMP or change any BIOS settings to run the RAM at 2666 MHz?

The modules are JEDEC-standard 2666 MHz CL19 at 1.2 V, so they run at rated speed automatically without XMP or manual voltage changes.

If a module fails years from now, what replacement options exist?

Computer Memory Solutions provides a limited lifetime warranty for exchange or repair against manufacturing defects when purchased directly from them.
