I'm not sure about that buddy, I'm on 32GB of decent RAM and the game conked out around 16gb and softlocked on me, even waiting for the process to un-f#ck itself, but alas she crashed and burned.
Must say, the game looks fantastic, frame rate was smooth enough, but there's definitely something up with that memory allocation in MP servers. I don't know what's causing it but it's definitely there.
