My motherboard is Asus h97 Pro, it says it supports memory that is 1333/1600 mhz speed. Can I use is Corsair Vengeance Pro at 2133 mhz? they don't sell 1600 mhz gold version for some reason.
It will be fine, you can set the speed manually in the BIOS/UEFI. H97 Supports memory overclocking, so if you set the speed it should work fine. If it doesn't then the memory will just downclock to the highest speed possible, but you should be fine.
