Hello,

I have a LGA1155 motherboard with 4 DDR3 RAM slot and 2x2gb and 2x4gb RAM(same manufacturer, same model and same speed).
How the Best to place them for dual channel?
4+4 and 2+2 or 4+2 and 4+2.
Thanks for the help.

Usually the board indicates DIMM 0 DIMM 1 etc around the slots to better identify them. If the right slots are populated it ll activate dualchannel regardless of memory capacity installed. Whenever that is the optimal thing is another matter. Stick the 4GB modules into slot 1 and 3 and the 2GB modules slot 2 and 4 .

Just one more question. 2 different sized Dual channel slower(thats how its now) than 2 same sized Dual channel? Or 2 different dual channel size dont have performance impact?
Most of the data would sit on one bank. And if 1 or more memory is slower the highest speed of the slower memory takes precedence and faster modules getting brakes squeezed on.(as they say , a computer is only as fast as its slowest component.) If they work at lower speeds , fine , if they don t your comp wont boot at all. Since u have 4 and 4 in dual channel and 2 and 2 in the other channel data can be split <evenly> to more or a less degree. effective bandwidth mainly, the idea is there.
