Ive checked Gigabytes supported list and its very short to say the least. I am looking for a 4gb chip (2x4gb total) at 2000mhz that this mobo supports. This is for a gaming rig that runs multiple applications during games, such as video recording. Likewise I will be doing video editing on this machine. I was hoping to spend around $100 but I have room to flex.
I'm not familiar with that motherboard, but it lists 2000 as (overclocked)... so its probly going to come set on 1600, and you will have to tweak the voltage and speed to achieve 2000. I know one person who bought a gigabyte board that was rated like this, and he never could get the thing to run stable at 2000.
*aside from that... RAM is not a bottleneck. Theres no real world difference between 8gb of either one. Even though you are multitasking heavily, still no difference. Only difference you'll see is in benchmark tests designed to measure ram speed... and even then it will be small.
It would be more cost effective to spend $60 on an 8gb kit of 1600... or spend $100 on an 8gb kit of 1600 with tighter timings.
