I also have G Skill trident Z5 RAM but 2x 32 GB on 6800 and it runs very well. Really recommendable. Not all Trident is recommended by the motherboard manufacturer. Have a look at the ROG support page (click on the same product and then support). There is a whole list with which RAM is supported/recommended and don't forget to enter the CPU gen!!! Make sure that the manufacturer number is exactly the same, as there are also Tridents from G.Skill that are not recommended but have the same name.
