Hi guys! I have 3x2gb patriot 1333mhz ram and 1 chinese noname 1333 2gb stick. The question is:can this ram bottleneck my system?
I have 3770k cpu and 1070ti z77x ud3h mobo(dual channel) and my avg fps in games like fortnite/overwatch/pubg is much lower than avg fps on youtube tests with same gpu/cpu like mine. Also i have huge fps drops in fights.

I'm not a fan of mixing and matching sticks of ram to get a cumulative number. Inf act you will need to cross reference their latencies and voltages as well as their maximum advertised frequencies. In all honesty even if you did get them to all run at the same specs in BIOS, they were not made off the same assembly line nor can you guarantee that they were binned the same.

With respect to your board+ram+processor you should be looking at a DDR3-1600MHz ram kit that is rated to run at 1.65v.

I wouldn't cross reference your specs with a YT video, IMHO. Lastly, list your specs like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:

1. There is no such thing as RAM speed bottleneck on your I7/5 3xxx platform. RAM speed plays almost no role in system performance.
2. Having FPS drops could be an indication that you do not have enough RAM.
3. Mix and matching RAM means only luck. If you are lucky, it will work. Nobody knows if it will work. If it works, the speed will be the slowest installed RAM kit/stick.

Youtube is not the best source for such information.

RAM speed influence the iGPU performance greatly but not if you game on dedicated GPU.
Ryzen platform gain benefit on faster RAM not on most of Intel's platform such as yours.
Some games do show benefit of having faster RAM but such games are very few and the jump ist not big.
