I have a Gigabyte 970a-ds3p motherboard (REV 2.0)and 2 x kingston hyperx fury 1600mhz memory (i buy these 2 memory separately) and then problem is i cant enable dual channel memory. i aready tried everything eg: changing slot , uncheck maximun memory and more

i am using windows 7 untimate (64bit)

If i put those 2 memory in my DDR3_4 and DDR3_2 slot i will be using 8gb in single channel mode, other than this combine is all 4gb in use and 4gb hardware reserve in single channel mode.

If the two sticks are not a matched set, you might not, as you are finding out, be able to set up dual-channel.
I had the same problem with an MSI board a couple years ago: I bought an additional stick of ram that supposedly was "identical" to the other 3 that I had, but the PC could never be set for dual channel mode IF that stick of RAM was used.
Upon replacement with a matched set of 4x2GB sticks, dual mode happened automatically.
Sounds like the same problem I had.
You have tried them in DDR3_1 and DDR3_2 together to get dual mode? (Per your manual).
