What this kit upgrades

This 32 GB kit contains two 16 GB DDR4 SODIMM modules rated at 2400 MHz with CL17 timing and 1.2 V operation. It is built specifically for the Dell XPS 15 9550 and 9560 platforms and uses unbuffered, non-ECC chips in a 2Rx8 layout.

Sustained-load behaviour

Because the modules run at standard JEDEC voltage and timings, they maintain their rated 2400 MHz speed during long workloads without thermal throttling or voltage drift. The lack of a heat spreader is normal for this form factor and the laptop’s own cooling handles the memory thermals.

Installation notes

Installation requires opening the laptop chassis to reach the two SODIMM slots; the 260-pin modules key into place with a firm, even press until the side clips latch. The only common issue is seating one module at an angle, which causes a no-post condition until both sticks are fully locked.

Questions about this item

Does the 1.2 V DDR4 2400 MHz kit run cool and quiet during all-day workloads?

The modules operate at the standard 1.2 V DDR4 voltage with no heat spreader, so they add minimal heat and produce no audible noise inside the Dell XPS 15 9550 or 9560 chassis.

Must the laptop already have two free SODIMM slots for this 2 x 16 GB kit to work?

Yes, the Dell XPS 15 9550 and 9560 each provide two 260-pin DDR4 SO-DIMM sockets, and this kit fills both to reach the 32 GB maximum.

Will the CL17 2Rx8 sticks work alongside any original 8 GB or 16 GB modules I keep in a 9550 or 9560?

The XPS 15 9550 and 9560 only have two slots, so the 2 x 16 GB kit replaces any existing memory rather than running alongside it.
