My Dell M4800 mobile workstation accepts EITHER 32M of 1600MHz OR 16M of 1866MHz. What's best for my CAD?

Sorry, I'm sure this is somewhere buried on this forum, but I can't find either it or a suitable guide. Lots of info for gaming, box, or overclocked systems, but my application is 95% CAD (Solidworks, Rhino, Meshlab, etc.) and sometimes some video and multimedia work.

My M4800 workstation was delivered with 8M of 1600, and it's not enough. I was a little surprised to be presented with the "either or option" but that's what it says. I can either buy 16M of 1866MHz, or twice as much 1600. Honestly it's not a recurring problem I've been having- and even then just a "warning" that my resources are running low, and I probably have too many things running concurrently anyway. So even with just 8M, it's a manageable system.

Really, the title sums up my question. Thanks for any help!

PS. My video card is the Nvidia® Quadro® K1100M w/2GB GDDR5. 3.7GHz . Intel Core i7-4800MQ Processor (6M Cache, up to 3.70GHz)

Not that it will be likely to use it, but the 1866 isn't faster enough than the 1600 to outweigh the fact that you would have double going with the 1600. So if your CAD software can actually use 16GB or more, get the 32GB of 1600. Get it with as low of latency as you can though, it won't make much difference, but some.

You could also upgrade to the K2100 GPU card.
