Ahh - the link is just to show the general ridiculousness of MOBO limits based on 4G sticks - not to recommend a product! They're damned hard to find any of for actual sale - I found a dozen citations of this announcement: http://www.techspot.com/news/30260-corsair-announces-20...
but further searching found none actually for sale, by the fifth google page, which is about as far as I go for nonsense like this...
The actual answer is that, with four slots, the limit is 8G, like all four slot boards; this is also as much as you're ever likely see any difference in the use of...
I run a four monitor system with 8G of RAM under W7x64; on one monitor, I have an industrial controller logic design program, often running in a VirtualXp box; on the second, a visual design program for the touch-screen controller that acts as the operator interface; on the third, a cad program with twenty or thirty pages of schematics open; and on the last one, VisualStudio to write 'glue-logic' to chunks of MSOffice programs; I actually see the difference between 4G and 8G, mostly in reduced swapping... For any x86 OS, or less demanding useage (excepting something 'thread-intensive' like video editing), the difference is marginal.
Due to chipset limitations, read the following guidelines before installing the memory in Dual or 3 Channel mode.
1. Dual Channel mode cannot be enabled if only one DDR3 memory module is installed.
2. When enabling Dual Channel mode with two modules, it is recommended that memory of the same capacity, brand, speed, and chips be used. When enabling Dual Channel mode with two memory modules, be sure to install them in the DDR3_1 and DDR3_4 or DDR3_1 and DDR3_2 sockets.
1. 3 Channel mode cannot be enabled if only one or two DDR3 memory modules are installed.
2. When enabling 3 Channel mode with three or four modules, it is recommended that memory of the same capacity, brand, speed, and chips be used. When enabling 3 Channel mode with three memory modules, be sure to install them in the DDR3_1, DDR3_2 and DDR3_4 sockets.
Read the following guidelines before you begin to install the memory:
• Make sure that the motherboard supports the memory. It is recommended that memory of the same capacity, brand, speed, and chips be used.
(Go to GIGABYTE's website for the latest memory support list.)
• Always turn off the computer and unplug the power cord from the power outlet before installing the memory to prevent hardware damage.
• Memory modules have a foolproof design. A memory module can be installed in only one direction. If you are unable to insert the memory, switch the direction.
• For the DDR3_2/DDR3_3 memory socket, make sure the memory module to be installed is a SA2 memory module.
• If only one DDR3 memory module is installed, it is recommended to install it in the DDR3_1 socket.
• When memory modules of different capacity and chips are installed, a message which says memory is operating in Flex Memory Mode will appear during the POST. Intel Flex Memory Technology offers greater flexibility to upgrade by allowing different memory sizes to be populated and remain in Dual/3 Channel mode/performance.
