OS installed : Windows 10 Home 64bit
I am having motherboard Gigabyte GA970-D3P with Corsair RAM 4gb DDR3 1600 CMZ4GX3M1A1600C9 installed in channel A slot 1. I want to have total 12 gb ram. As my motherboard has dual channel capacity. Can i add Corsair RAM 8gb DDR3 1600 CMZ8GX3M1A1600C10 in slot 3 of channel b to get dual channel performance thereby improving my computer's performance for designing works... Gaming to an extent.
I have seen that both the memory module has different latency and memory configuration
CMZ4GX3M1A1600C9 with 9-9-9-24 latency and memory configuration as Single Module
CMZ8GX3M1A1600C10 with 10-10-10-27 latency and memory configuration as Quad Channel
Can i use both the RAM's together
If yes then what needs to be done in BIOS for optimum performance.

Mixing RAM types of different CAS latency is not recommended. If it does work, it puts an extreme burden on the memory controller which will struggle to maintain stability.
If the memory is free, you can try it, but the chances of it working and being stable are very low. Might not even BOOT. If it does, day to day computing tasks could work, but the moment you challenge the system, it might lockup, BSOD or fail. I wouldn't bother trying, as using matched kits or at worst using different brands together with identical latency would be a better choice. Keep in mind, even (same brand) unmatched kit can be iffy.
The days of pairing faster RAM with slower RAM and running at a slower overall speed are over. The "tolerances" have been tightened due to users performance and over clocking demands. BIOS and XMP profiles are more stringent as well. My advice is don't do it. You are risking system stability.
