4GB DDR4 2400 DIMM for Dell XPS

This 4GB DDR4 2400 CL17 module is built for Dell XPS 8900, 8910 and 8920 desktops. It runs at 1.2V as an unbuffered non-ECC DIMM with 2Rx8 organisation. The stick adds capacity to compatible systems without requiring configuration changes.

Check slots and maximum capacity

Verify the motherboard has a free 288-pin DDR4 slot before ordering. The platform supports up to 64GB across four sockets so total capacity after installation must stay within that limit. Existing modules should match the 2400MHz speed and 1.2V voltage for best stability.

Steady throughput at rated timings

Under sustained load the module maintains its 17-17-17 timings at the rated 2400MHz frequency. The major-brand chipset and lack of a heat spreader mean thermal headroom depends on case airflow rather than onboard cooling. Performance remains consistent during extended workloads within the rated voltage.

Questions about this item

Does the single 4 GB stick ship alone or with extra brackets or cables?

The package contains one 288-pin DDR4 DIMM only; no brackets, cables or additional hardware are included.

My XPS 8920 has four slots and supports 64 GB total — should I add one 4 GB module or fill every slot?

Each slot accepts up to 16 GB, so a single 4 GB stick works immediately; you can add more later up to the 64 GB limit across all four sockets.

The module is rated 2400 MHz CL17 — will it actually run at that speed in my 8910?

Yes, the XPS 8910 supports DDR4-2400 natively, so the stick will operate at 2400 MHz with 17-17-17 timings at 1.2 V without manual changes.
