Note:
*Specifications are subject to change without notice

**The actual Max memory capacity that could be recognized under a 64-bit OS will
be less than 4GB due to the conflict in the memory space of the MMIO mapping.

*** As the operating temperature provided in the specifications is a result of the test
performed in VIA’s chamber, a number of variables can influence this result. Please
note that the working temperature may vary depending on the actual situation and
environment. It is highly suggested to execute a solid testing and take all the
variables into consideration when building the system. Please ensure that the system
runs well under the operating temperature in terms of application.
