I'm currently using this mobo with the older model of the Corsair Dual Channel Memory Dominator 2x2gb CMP4GX3M2A1600C9...
I was using it for more than 4 years and recently the memory is giving me problems..so I've sent it for warranty since it's lifetime warranty... So the distributor here in my country said to me that this model already discontinue.. they offer me another similar model which is cmp8gx3m2b1333c9... it's bigger memory but with lower speed..so I've no choice but to accept it..

So now I received the new ram and install it into my mobo... when I try to install them in Dual Channel slot it doesn't boot...so I tried to install both in different channel and it does boot...


I've tried setting the ram speed at 667mhz and 1.6v power in the bios...still can't boot in dual channel..


In-between the warranty claim period I got no ram to use for my pc so I bought a new cheap Kingston so-call performance ram which is the HyperX (X316C10FR/8)

Desktop specs:
Power: Cooler Master SilentPro 600W
M/B: M4A785TD-V EVO
CPU: AMD Phenom II x4 965 BE
GPU: ASUS GTX550 Ti TOP
Memory: 1 Corsair 4gb (the new ram that I claimed) + 1 Kingston 8gb (the 1 I newly bought) = Both install in single channel.. the extra ram corsair that comes in a pair is left aside...

Conclusion...I just want to run my ram in dual channel like I did before...Please help me out in this 1...your help will be much appreciate..thank you
 
You can't have two RAM dimms from two different manufacturers.You can damage your motherboard like that.
You must use IDENTICAL RAM if you want your PC to work properly.
Remove the Corsair DIMM or the Kingston DIMM and you will be able to boot your system.

I tried all possible combination.. It only boots in single channel slot.. I checked with CPU-Z to see if it's running single or dual
