Dell XPS 8900, 8910 and 8920 memory kit

This 32 GB kit contains two 16 GB DDR4 DIMMs validated for Dell XPS 8900, XPS 8910 and XPS 8920 desktops. Each module runs at 2400 MHz with CL17 timings at 1.2 V. The unbuffered, non-ECC design matches the factory specification for these systems.

32 GB capacity and DDR4 2400 headroom

The 32 GB total fills two of the four available slots, leaving room to reach the platform maximum of 64 GB. At 2400 MHz the kit delivers PC4 19200 bandwidth for everyday multitasking and content workloads. Applications that demand higher frequencies or lower latencies will not benefit from this specific speed grade.

DDR4 288-pin DIMM interface limits

The 288-pin DDR4 interface caps transfer rates at the rated 2400 MHz, so faster modules will downclock to this speed. Only unbuffered, non-ECC DIMMs are supported; registered or ECC memory will not function. The four-slot topology restricts total capacity to 64 GB regardless of module density.

Questions about this item

Will the 2400MHz DDR4 modules run at full speed alongside the original memory in my Dell XPS 8900?

The kit is tested for Dell XPS 8900, 8910 and 8920 desktops; install the two 16GB sticks in the remaining slots and the system will negotiate the highest common speed automatically.

How do I verify the CL17 timings and 1.2V operation are active after installing the C114 kit?

Enter the UEFI/BIOS on the XPS desktop and check the memory information screen — it will report DDR4-2400, 17-17-17 timings and 1.2V.

Does the package contain only the two 288-pin DIMMs or are any cables or tools included?

The box holds the two 16GB DDR4 DIMMs only; no cables, screws or tools are supplied.
