new MSI gaming laptop RAM issue

[Ezibelle]

Hello everyone,

I am having an issue with my new MSI GE72MVR 7RG laptop, the issue is that games aren't running very well, it has an i7 7700HQ and a gtx 1070 with 1x16GB DDR4 2400Mhz RAM. Games like Rainbow six siege, Destiny 2, and Battlefield 1 will run somewhere in the 70-100FPS zone maxed out at 1080p but will have extremely low 1% lows like down to 25 and 30FPS and during these spikes the game will hitch for a second then go right back up to the normal framerate. Now I have done some research and it seems that the issue is with having a single stick of RAM rather than a dual channel memory kit. RAM prices are pretty high right now so I am thinking to help alleviate this issue I might just buy a 4GB 2400Mhz stick on the cheap and get some of that dual channel goodness.

 

My question is, is that a viable option? I mean the RAM that came with the laptop is 16gigs and is Samsung brand I believe, would I be able to buy a 4GB stick of crucial that is the same speed and just pop it in no issue? I want to fix this issue as cheaply as possible.

Thanks in advance for taking the time to read about my issues

That would work.

 

Any reason you're not aiming for another 16Gb stick?

Just that they are fairly expensive at the moment and I am short on cash. $40USD for a 4GB stick is a lot less than the $150 or so for another 16GB stick

Have you checked the used market for DDR4 SO-DIMMs?

I will definitely look around for some used ones now that I know I can mix and match with no issue.
