Populating SODIMM sockets
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.
Table 2-2 Identifying SODIMM locations
Location System board label Channel
Lower Socket SODIMM1 Channel A
Upper Socket SODIMM3 Channel B
●
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.
Installing SODIMMs
There are two memory sockets on the system board. To remove or install memory modules:
1. Remove all removable media, such as compact discs or USB flash drives, from the computer.
2. Turn off the computer properly through the operating system, then turn off any external devices.
3. Disconnect the power cord from the power outlet and disconnect any external devices.
CAUTION: You must disconnect the power cord and wait approximately 30 seconds for the
power to drain before adding or removing memory modules. Regardless of the power-on state,
voltage is always supplied to the memory modules as long as the computer is plugged into an
active AC outlet. Adding or removing memory modules while voltage is present may cause
irreparable damage to the memory modules or system board.
4. Remove/disengage any security devices that prohibit opening the computer.
5. 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 bezel and screen surface from scratches or other damage.
