Dell XPS 8900/8910/8920 memory upgrade

This 64 GB kit (four 16 GB DDR4-2400 modules) is built specifically for Dell XPS 8900, 8910 and 8920 desktops. It delivers a matched, non-ECC, unbuffered DIMM set that installs directly into the four available slots. Buyers who need ECC error correction or registered modules should look elsewhere.

Capacity and headroom for multitasking

The 64 GB total fills the platform maximum and runs at 2400 MHz with CL17 timings at 1.2 V. It handles heavy multitasking, large datasets and virtual machines without paging. Workloads that exceed 64 GB or require faster memory speeds will hit the system ceiling.

Replacing the factory configuration

The kit replaces the original lower-capacity sticks and upgrades the desktop to its full 64 GB limit in a single step. The jump is worthwhile when the current memory is below the maximum or when mixed modules cause instability. Systems already at 64 GB gain no additional capacity from this kit.

Questions about this item

Will these 288-pin DDR4 2400 modules run at their rated speed alongside the original memory in my XPS 8900?

The kit is guaranteed compatible with the XPS 8900, 8910 and 8920 desktops. All four 16 GB modules operate at 2400 MHz with CL17 timing and 1.2 V. The system will configure the memory automatically.

How can I verify the 64 GB kit is detected at 2400 MHz with CL17 timings after installation?

Open Task Manager or BIOS and confirm 64 GB total capacity, 2400 MHz speed and 17-17-17 latency. CPU-Z will show each 16 GB DIMM running at 1.2 V unbuffered.

Does the CM2048642400DIMM package include only the four DIMMs or are any tools or cables supplied?

The box contains four 288-pin DDR4 DIMMs and nothing else. No tools, cables or additional hardware are included.
