Memory
Description
4GB memory module
There are two DIMM sockets on the system board, with one socket per channel. The sockets are labeled DIMM1 and DIMM2. Socket DIMM1 operates in memory channel B. Socket DIMM2 operates in memory channel A.
The system will automatically operate in single channel mode, dual channel mode, or flex mode, depending on how the DIMMs are installed.
NOTE: Single channel and unbalanced dual channel memory configurations will result in inferior graphics performance.
●The system will operate in single channel mode if the DIMM 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 DIMM in Channel A is not equal to the memory capacity of the DIMM 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 DIMM in the system.
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

Static electricity can damage the electronic components of the computer or optional cards. Before beginning these procedures, ensure that you are discharged of static electricity by briefly touching a grounded metal object.
When handling a memory module, be careful not to touch any of the contacts. Doing so may damage the module.
To remove a memory module:
1.Prepare the computer for disassembly (see Preparing to disassemble the computer on page 14).
2.Remove the access panel (see Access panel on page 15).
