Questions about this item

How much power does the DDR4 2933 kit draw when the laptop runs all day?

The modules operate at the standard DDR4 voltage, so power draw stays within normal SO-DIMM limits during continuous use.

What must the laptop provide for these 260-pin DDR4 SO-DIMMs to work?

The notebook needs two free DDR4 SO-DIMM slots that accept 260-pin modules and support the PC4 23400 speed rating.

Will the PC4 23400 speed work in a system that originally shipped with slower DDR4 memory?

The kit runs at DDR4 2933; the memory controller sets the final speed, so it will operate at the highest rate the platform allows.
