Will this ram be fine for gaming

Solution
there is no such thing as "gaming" RAM. same goes for motherboards, PSUs and any other component.
It's pure marketing BS to milk more money from unthinking majority.
if this RAM compatible with your system, it will work just fine.
In theory any DDR3 ram kits can drop into a board that supports DDR3 ram but in reality there are minor shifts within the rams manufacturing process and the layout of the IC's on a ram stick which can and will hamper the use of said ram kits. You should list your specs like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:

Also, mixing and matching rams are a bad practice and can only lead to more troubleshooting(and headaches).
