My motherboard supports up to 24gb of memory and has six slots. I mainly use my PC for gaming, how much RAM will I really need for my PC? 6 or 12gb? If I decide to get 12/24 gb will my PC utilise all the RAM?
I'll assume you're using a 64-bit OS, because if not, you won't use more than 3.75GB, regardless of your mobo's limitation. Generally, gaming isn't very demanding on RAM. You really won't need more than 4GB (2GB, really, but if you're rocking Windows Vista or 7, the mininum for 64-bit is 2GB; so add in 2GB for gaming and you get 4GB.

was thinking of installing 6GB RAM 2000 Mhz (3 modules) or can install 12GB 1600 Mhz (3 modules-but more expensive option).
