Pros & Cons

Pros

  • ✓ 5600MT/s DDR5 speed in a SODIMM, well above stock laptop memory
  • ✓ Plug N Play auto-overclocks with no BIOS profile to enable
  • ✓ Runs at 1.1V for lower power draw and less heat in tight chassis
  • ✓ On-die ECC corrects in-DRAM bit errors for added stability

Cons

  • ✗ CL40 latency is loose; tighter-CL kits exist at the same 5600MT/s
  • ✗ SODIMM only, so it will not fit a standard desktop DIMM slot
  • ✗ Plug N Play speed depends on your laptop's memory controller support
  • ✗ XMP 3.0 profiles are unusable on laptops with locked firmware
