The system will automatically operate in single channel mode, dual channel mode, or flex mode, depending on how the SODIMMs are installed. Refer to the following table to identify the SODIMM channel locations.

●The system will operate in single channel mode if the SODIMM sockets are populated in one channel only.
●The system will operate in a
●The system will operate in flex mode if the memory capacity of the SODIMM in Channel A is not equal to the memory capacity of the SODIMM in Channel B. In flex mode, the channel populated with the least amount of memory describes the total amount of memory assigned to dual channel and the remainder is assigned to single channel. If one channel will have more memory than the other, the larger amount should be assigned to channel A.
●In any mode, the maximum operational speed is determined by the slowest SODIMM in the system.
There are two memory sockets on the system board located behind the memory access panel. To remove or install memory modules:
To remove a memory module:
1.Prepare the computer for disassembly (see Preparing to Disassemble the Computer on page 33).
2.Place the computer face down on a soft flat surface. HP recommends that you set down a blanket, towel, or other soft cloth to protect the screen surface from scratches or other damage.
3.Remove the center access panel (see Hinge Cover Panel on page 34).
4.Remove the memory access panel (see Memory Access Panel on page 36).
