Serious What RAM you use?

All depends on what you need, I have 16 gigs of ddr4 on my main pc right now but for most people 12, 8, or even in some cases 4 gigs will do.

16 GB is little to many for me, I have 8 GB and never had problem with that.

i use ddr4 2400Mhz in 2x8GB. Verify your motherboard allowing frequency

Crucial Ballistix Sport LT 16GB is what I use. Pretty good I guess.

I think that my current laptop has 8 GB of RAM which I think is pretty standard.

I am currently using 24 GBs of DDR3 (2x 4GB Corsair PC3-10700 , 2x 8GB Corsair PC3-10700)

I have a 16GB RAM for my PC, I might upgrade it in the future.

i use dd4 rams on my PC, idk what brand they are from but I don't think they're from a good one, anyways, any ram you buy should do the work. Branding is the less.

I use a corsair vengeance 8gb ddr3 it is good but a bit old

Trident Z RGB 16GB DDR4 3000MHz
