●
The system will operate in single channel mode if the SODIMM sockets are populated in one
channel only.
●
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.
●
The system will operate in a higher-performing dual channel mode if the memory capacity of the
SODIMM in Channel A is equal to the memory capacity of the SODIMM in Channel B.
●
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 32).
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 access panel (see
Access panel on page 36).
4. To remove a memory module, press outward on the two latches on each side of the SODIMM
(1), then pull the SODIMM out of the socket (2).
