4GB DDR3 option on A64+ units

[SkimMilk]

Dear Pine64 Development Team,

I had a question regarding memory capacity on the A64+ units. Would it be possible to offer a 4GB DDR3 option for just a couple dollars more over the 2GB option? Our news team recently wrote a story about the Pine A64 and some of our readers have suggested that a 4GB A64+ option would make the device much more usable as a PC. This would also allow the device to make full use of the 64-bit memory address space.

Please let us know what you guys think. Looking forward to your response.

The highest DRAM capacity for Allwinner A64 chip is 3GB. If 3GB stil make sense to explore, we will check out on Fenruary time frame once clear up on Becker delivery.

Dear Pine Team,
as opposed to just limiting the onboard RAM, what would you think about a SODIMM slot that could handle up to 4GB sodimm? Or two, for up to 8GB? I think this would make for much more flexibility for end users and developers.
My additional thought - the "sign" enclosure, a touchpad, bluetooth, and a GPS module would make this an ultimate navigation and entertainment module (via linux, most likely) to embed in a car.

tllim has stated that the A64 chip can only address up to 3GB, so, that's the max it can go...
