The gang over at A-DATA has added a nice little update to their DDR3 line. They have added a 4GB single module option for all of their DDR3 products. This includes Desktop, Laptop and Server Memory.
This move matches a few other companies that are increasing the capacity of their single modules, with the exception of making the move across the entire line.
The new modules should start showing up in the channel immediately and if the pricing is in the right area could open up good options for memory upgrades.
Of course there is the small problem of support. While Linux has support for more than 4GB of RAM in a 32-bit OS, Windows 7 and Windows Vista do not. This could make the market for these slightly limited outside the enthusiast and x64 community.
