Targeted DDR4 upgrade for Dell XPS desktops

This 8 GB kit contains two 4 GB DDR4-2400 DIMMs built for the Dell XPS 8900, 8910 and 8920. Non-ECC unbuffered modules run at 1.2 V with CL17 timing and a 2Rx8 rank structure. The 288-pin form factor matches the four slots available in those systems.

Compatibility checklist before purchase

Confirm your motherboard has free DDR4 DIMM slots and supports 2400 MHz operation at CL17. The platform maximum is 64 GB across four sockets, so total capacity after installation must stay within that limit. Verify the existing memory voltage is 1.2 V to avoid mismatched modules.

Replaces slower or smaller factory memory

Swapping original lower-capacity or lower-speed sticks for this matched pair raises total bandwidth and multitasking headroom. The jump is worthwhile when the current configuration leaves empty slots or runs below 2400 MHz, and when the 64 GB ceiling meets future needs.

Questions about this item

Does the kit include both DIMMs or do I need to order a second stick separately?

The package contains two 4 GB DDR4 DIMMs for a total of 8 GB, so nothing extra is required.

Should I pick the 2400 MHz CL17 kit or a faster speed for my Dell XPS 8920?

The XPS 8900, 8910 and 8920 all support DDR4 2400, so this 2400 MHz CL17 kit matches the platform specification.

Will the 2400 MHz rating actually run at that speed once installed in my XPS 8910?

The modules operate at DDR4 2400 (PC4 19200) with CL17 timing at 1.2 V, delivering the rated speed on compatible Dell XPS desktops.
