I'm planning on ordering an M4 soon, but I want to upgrade the ram myself to save money. However before I order the ram I need to know if the M4 uses dual channel or not. Also I need to know the maximum amount of RAM the M4 supports since I've read that adding more ram than a computer can support will not only be wasteful, but may also cause the computer to slow down and potentially though rarely may cause damage to the hardware. Atleast that's what it says on crucial's site. However since this tablet model is pretty new I can't find any information about how much RAM it supports. Toshiba's site has a max upgrade of 1.5 gigs, but I'm not sure if this is the max and also not sure if it's dual channel since this upgrade seems to point otherwise. If anyone has any info on this please help.
