Do you think that if I upgrade it to 16 GB I will be able to use After Effects easily again so I can finish my project?
I'm surprised that you were able to use it with only 8GB RAM.
Definitely install as much RAM as you can fit and afford.
Thank you very much for your answer. Actually I got surprised too at the beginning, I didn't think I'd be able to make so much with this RAM, but it did the job pretty well (maybe it's thanks to the SSD, I don't know.) I'm sorry but I'm not an expert in computer science haha. Do you know roughly how much RAM this kind of project would need? Would 16 GB be enough according to you? I don't want to upgrade it then realize that I still encounter the same issues...
I can't say for sure. There may be another bottleneck, such as your processor. You'll have to try it.
Yes, Thank you ! I checked my processor, I have a i5-4670. I guess I should change it for a i7 one... Anyway, I'm going to upgrade the RAM before, then I'll see if it does the job !
You should be able to work with 8 GB of RAM (although, adding more is highly recommended). The surprising thing is that it was working and then suddenly stopped behaving. SOMETHING changed - we just need to figure out what it was. Did your OS update? Was any software installed? Was any hardware installed?
My first thought is that one of your RAM sticks is starting to go bad, so if you're replacing your RAM anyway, that should solve the issue (unless it's your motherboard...)
