MODEL NO PH315 -52 i.e. is a predator 300 helios ...i needed help with the RAM ...

LYRICz

hey I have the 16gb(single channel 2666mhz) in stock ram model and I  wanted to upgrade the ram and I wanted to make it dual channel as I have heard many people saying that it makes a lot difference in the gaming fps so do I have to add 16gb more 2666mhz or do I add 8gb ram 2666mhz will there be a difference in performance btw 8gb is currently in my budget . will adding ram of difference capacity but same clock speed hinder or downgrade the performance of the laptop  all the current games which I want to to play minimum requirement is 8gb ram so plzz tell ("16+8gb ram 2666mhz ") or (16+16 gb ram 2666mhz ") which one should I go for and what is the difference In both of them in performance... and how to toggle between  on and off the predator logo at back of the screen panel if there is a way plzz tell me...

can you send some screenshots showing the memory settings on the cpuz? have you ever thought about getting a pair of hyper x or vengeance memory?
