I could not find your motherboard on the ASUS site.
These are the two processors you are asking about:
No, you cannot upgrade for two simple reasons.
1, they use different sockets
2. they are soldered to the motherboard.
Even if they used the same socket, and were not soldered, the ASUS BIOS would have to support the upgrade processor.
For any upgrade, the upgrade processor has to be socket, BIOS, and chipset compatible.

Also, when you find your motherboard on the ASUS site, there will be a list of compatible processors/CPUs. But, all of this is moot as your processor is soldered to the board.
Regarding memory, the amount of memory is dictated by the motherboard. Look at the specifications for your board.
