Preface
Before using this information and the product it supports, please read the following general information.
1. This service guide provides you with all technical information relating to the basic configuration
decided for acer's "global" product offering. To better fit local market requirements and enhance
product competitiveness, your regional office may have decided to extend the functionality of a
machine (e.g. Add-on card, WLAN card, modem, com card or extra memory capability). These
localized features will not be covered in this generic service guide. In such cases, please contact
your regional offices or the responsible personnel/channel to provide you with further technical
details.

Memory module combinations
You can install memory modules in any
combination as long as they match the
specifications.
Note: Due to CPU limitations, read the following guidelines before installing the memory in Dual Channel
mode.
1. Dual Channel mode cannot be enabled if only one DDR3 memory module is installed.
2. When enabling Dual Channel mode with two or four memory modules, it is recommended that
memory of the same capacity, brand, speed, and chips be used. For optimum performance,
when enabling Dual Channel mode with two memory modules, we recommend that you
install them in the DDR3_1 and DDR3_2 sockets.
