System-specific DDR4 kit for Dell desktops

This 32 GB kit contains two 16 GB DDR4 2666 DIMMs built to the exact specifications of the Dell G5 5090 and Inspiron 5680. The modules run at 1.2 V with CL19 timings and use unbuffered non-ECC chips on a 288-pin interface. Each stick is a 2Rx8 rank configuration validated for those two models.

Replaces factory memory when four slots are

The supported platforms accept up to 64 GB across four sockets, so this two-module kit fills half the available slots. Upgrading is worthwhile when the existing configuration leaves empty sockets or when the installed modules run at a lower speed than 2666 MHz. Buyers who need more than 64 GB total capacity cannot use this kit alone.

Limited to DDR4 2666 on the qualified Dell boards

The memory operates at the 2666 MHz data rate defined by the PC4-21300 standard and will not exceed that frequency on the listed systems. Compatibility is guaranteed only for the G5 5090 and Inspiron 5680; other motherboards, chipsets or form factors are not covered by the validation. Systems requiring ECC or registered modules cannot use these DIMMs.

Questions about this item

Will the 288-pin DIMMs fit the four slots in my Dell G5 5090?

Yes, the kit uses standard 288-pin DDR4 DIMMs that match the four memory sockets on the Dell G5 5090 and Inspiron 5680.

What is the correct way to seat the two 16 GB sticks so the system recognises the full 32 GB?

Insert each module vertically until the side clips click; the notch is off-centre so it only goes in one orientation — forcing it backwards is the common mistake.

When should I expect to replace these CL19 2666 MHz modules?

DDR4 memory has no moving parts and runs at 1.2 V; under normal desktop use it typically lasts the lifetime of the system, so replacement is only needed if a fault develops.
