Well since your not going to OC your ram, its better to get the Ram with the Ram speed area like you want, 24 gigs?, thats a bit much. save some money and get a 16 gig kit. Windows probably won't use 16 gigs for a long time...
I'm not worried about windows using 24gb ram, more interested in my adobe after effects using that much. rendering HD video uses ALOT.
And I have windows 7 ultimate which allows up to 24gb ram.
But from everything I have read, the Cas latency is the speed, I currently have 8. if I find something with 9 does that mean its going to be a ton slower? or will more cards make it faster then i currently have? these are the questions I have.
