8GB RAM vs 16GB RAM

[cRsFisA]

Right now I'm using 2x4GB RAM DDR4 2400Mhz Cl14 from Corsair

I usually play games like PUBG,but I've tried playing Forza Horizon 4 and Devil May Cry 5. All of them run just fine but they have some weird stutters from time to time. My guess is that I don't have enough RAM. Will upgrading to 16 help?

Specs: 

i5 7400

Corsair Vengeance LPX Black 8GB DDR4 2400MHz CL14 Dual Channel Kit

MSI RX 480 4GB GAMING X

MSI B150 GAMING M3 Motherboard

nJoy 550w PSU 80+ Bronze

1TB HDD WD BLUE

240SSD Kingston A400

Have you monitored your ram usage to see if thats the actual cause or not?

Also for the love of god replace your PSU with something that isnt a housefire. Im not even super into the whole "everyone must have a god tier psu" thing, but njoy is one of those fake badged ebay power supplies, thats a dangerous game youre playing with your hardware.

Well I'm having this PSU for over a year now and my PC didn't catch on fire.
Also, please stay on the subject.

It could be a combination of factors, of which ram is just one of them.

 

8GB ram with a 4GB GPU is on the low end for more modern titles. Going up to 16GB should help for more demanding graphical games. You could run monitoring software to see how much VRAM and system RAM is in use during gaming.

 

Other possible factors are the CPU. 4 core 4 threads is ok for average framerates, but you may experience more variation than if you had for example a 4 core 8 thread i7 CPU. I wouldn't look to upgrade CPU unless it was very cheap to do so. Maybe one to consider after ram.

 

And finally, it could be the storage too. If the games are installed on the hard disk, then if it needs to load on the fly there may be some stutter from that. Increasing the system ram could help in this scenario too.

So upgrading ram to 16 should be my priority right now?

It is most likely to provide some benefit, but I'd still check your actual system usage while gaming. While a game is running in a representative area, alt-tab out. I'd suggest using GPU-Z to look at how much GPU ram is in use, and at the same time, use task manager to see how much system ram is in use. If system ram usage is high, it doesn't necessarily need to be completely full as Windows will manage it to keep some free, it could help. Adding say another 2x4GB looks possible with your motherboard, and isn't too expensive an upgrade.

You priority should be upgrading that power supply, as someone above has said.

Look like your whole system is seeing its limits, i would look into building a new one, or let the PSU ruin it for good
