RAM + CAD = Memory Overload!

[CarpeNoctem]

Hey guys!

I know I can always trust you when I am unsure of a situation So try this one on for size...

Right now I have 8 gigs of RAM and am designing 3D models using CAD software. Each model uses around 1 gigabyte of memory to edit and 1 gigabyte of memory to render (my models contain thousands of feet of industrial piping systems). So I can only use 4 drawings at once before my computer starts to slow down greatly.

Obviously, I need more RAM because I have tried increasing virtual memory and it still slows down at the same time.

My question to you folks is, should I go for high speed memory and less gigs. OR should I go with slower speed memory with more gigs? I am sorta new to 3D modeling so I am unsure about which would be better for the kind of work my computer will be doing. And as of right now, I am the most knowledgable in my office with computers. Scary thought :|. I am thinking 12 gigs of the highest speed or 18 gigs of the lowest... or one of the lowest speeds. My mobo allows for 24 gigs but that seems like overkill

Thanks in advance!

I think you should lean toward the higher amount of memory, while also keeping the speed of RAM at a minimum of 1333.
