I have just checked the compatibility with your motherboard and the sticks you have according to your specs and I noticed I should have done this way earlier..
It seems the memory isn't supported for your motherboard.
You can check the compatibility if you want here
I have filled in:
Select manufacturer: Giga-byte
Select product-line: Giga-byte motherboard
Select model: GA-X58A-UD3R
