Dell XPS desktop memory kit

This 16 GB kit contains two 8 GB DDR4 DIMMs rated at 2400 MHz with CL17 timings. It is built specifically for Dell XPS 8900, 8910 and 8920 desktops and runs at the standard 1.2 V without ECC or buffering. The unbuffered, non-ECC design matches the memory controller in these systems.

Upgrading from 8 GB or less

Systems shipping with a single 8 GB module or a pair of 4 GB modules will see a direct capacity increase to 16 GB in dual-channel mode. The jump is worthwhile when the current memory limit forces swapping during multitasking, large spreadsheets or light creative workloads. Boards already populated with two 8 GB sticks cannot use this kit without removing existing modules.

DDR4 2400 platform ceiling

The XPS 8900, 8910 and 8920 platforms support a maximum of 64 GB across four slots. This kit occupies two slots at the highest native speed the memory controller guarantees without overclocking. Builders needing more than 64 GB or speeds above 2400 MHz must choose a different desktop platform.

Questions about this item

Will these 288-pin DDR4 DIMMs fit the four slots in my Dell XPS 8920?

Yes, the kit is built for the XPS 8900, 8910 and 8920 desktops which each have four DDR4 DIMM sockets supporting up to 64GB total.

What is the correct way to seat the two 8GB sticks so the system recognises 16GB?

Insert each module until the side clips click; a common mistake is stopping when the gold contacts disappear but before the clips lock.

Do these unbuffered non-ECC modules need any firmware updates or battery changes over time?

No, DDR4 DIMMs have no firmware or batteries; they simply remain in place unless you upgrade capacity later.
