Update system BIOS immediately following memory upgrade. Press "F2" to enter BIOS Setup when device is powered on. On the first screen under "System Memory" user should see"Installed Size: 2048MB". Exit BIOS Setup and save changes.
If BIOS is not updated correctly, it may be possible that the system configuration information will not be updated and Operating System shows only 0.99GB of installed RAM.
System supports faster speed modules, but Intel Atom processor runs memory bus at up to 667MHz.
