Just try loading Default not Optimized Default
2x GSkill F3-12800CL9-4GBXL is stated to run 184.108.40.206 @ 1600MHz
2x GSkill F3-17000CL11-4GBXL is stated to run 220.127.116.11 @ 2133MHz
So the timing you set will work for the GSkill F3-17000CL11 kit/sticks, probably will not work for GSkill F3-12800CL9.
