The CORSAIR Dominator requires too much voltage to be compatible with your current memory. Anyhow I wouldn't recommend memory modules that require so much voltage to achieve slightly lower timings.
Not all motherboards like 4 modules without increasing the voltage a bit and/or loosening the timings. Installing modules that have different characteristics could prove a bit challenging. You could certainly add a kit of identical A-DATA RAM. If you don't need more than 4 GB (unless you run VMs, you probably don't), buy a kit of G.Skill and sell the A-Data.
