Ram causing Stuttering/Freezing?

[Sumolizer]

I have a i5 2400 and 8gb ddr3 1333mhz and a GTX950.

I usually play games like Apex Legends, Realm Royale and Dying Light.

I get around 85-100 fps in each game but with constant fps drops.

So i locked the fps to 60 with Vsync.

But still the FPS is dropping from 60 to 45 or 50 after almost every 10 seconds.

This is very annoying as Neither CPU nor GPU are maxed out.

The Temps also are quite fine (50C for CPU ingame)(55C for GPU ingame)

I think my Ram is causing it because 

I have weird configuration.

Its 2gb+2gb and 4gb in the order.

Should i replace those 2+2 with a single 4 gb module?

Will it solve the problem?

If you remove both 2gb or the 4gb does the problem still exist? When it still exists it isn´t the Problem.

If i remove 4 gb or both 2gb sticks then i will definately get huge amount of freezes as 4gb ram is not enough for any game that i play
