Does anyone know if the following Kingston dual 16GB RAM kit is compatible with Dell XPS15 9550 currently running 8 GB factory RAM?
Kingston Fury 32GB DDR4 SDRAM Memory Module - 32 GB (2 x 16 GB) - DDR4-2666/PC4-21333 DDR4 SDRAM - CL16 - 1.20 V - Unbuffered - 288-pin - DIMM
288 pin is desktop memory. You need 260 pin SO-DIMMs.
My experience upgrading the Dell XPS 15 9550 to 64GB (2x32GB) here, along with my supposition that compatibility issues are related to too-fast CL timings.
