A few years ago I asked if 12gb of RAM was excessive. Turns out, 12gb was IDEAL. And now here we are again with the next evolution of upgrades. My win7 setup uses about 4-5 gigs of RAM on boot (with basic apps I always have open -- outlook, skype x 2, evernote, etc. -- does not include browser). But when I open chrome (granted, with a lot of tabs open), memory usage shoots up to 11-12GB. I've googled around for why chrome uses up so much ram, but everyone seems to say the same thing -- because it's programmed to be a mem hog and thats why the performance is so good. Fine, i guess we're going to 24gb then. First, my specs: Core i7 730 Gigabyte GA-X58A UD3R v2.0 12gb G.Skill RAM (3x4gb) - http://www.newegg.com/Product/Produc...82E16820231356 Win 7 x64 Now what i'm wondering is if i should: a) buy the exact same memory from new egg again ($80) to make 6x4gb = 24gb or b) Remove the existing 12gb DDR3 and replace with 3x8gb of rougly equivalent corsair ram. (http://www.amazon.com/Corsair-1x8GB-.../dp/B006XB56VI) ($120) I don't recall reading anything where using all the mem slots up causes it to run at a slower speed. I think that was something that used to only happen on older systems? Thoughts?
