Hello,
i can get 18GB of 1333 RAM, or 12 of 1600, is there a difference? does MORE, really mean MORE speed?

More about : whats ram 1333 1600

1600 is faster memory..

1600 offers more memory bandwidth overall. ALTHOUGH 1333 is the limit of the i7's warranty. So, if you blow something up, first thing Intel's going to ask is what speed your memory is running. Just so you know.

That said, people are running 2100+ MHz memory without killing the IMC, so you'll realistically be fine. :)

depends on the CAS timings; I'd personally take the faster memory if the timings/latencies are equal, but, they rarely are. (I'd expect the '1600' mem probably needs '9' settings, where the 1333 you can get 7.

no, memory speed combined with certain timing is related with memory bandwith (of whatever quantity) while X GB means just quantity and doesn't relate with memory speed.

in short - if application needs 8GB you'll be better with 8GB of faster RAM than 10GB of slower RAM...

having more memory means more application running in RAM, thus swapping between application is much faster than in the case when you have just a little less RAM memory. In this case when you need to switch between applications, first your computer will store inactive application to HDD (swap) and load the new application from HDD. Reading/writing to HDD is way slower than reading/writing to RAM...

Aha! I didn't catch that little bit!

@OP: No, more size does not mean more speed. The only things that affect speed are timing and frequency (along with a few other factors but these are generally nominal in their impact)

Other than synthetics I'd doubt you would see any difference between 1600 and 1333 at equal timings.

And if I had 18GB of memory I'd commit 12GB of it to a RAM-disk for "Hot Files"

For AMD:

1600 works best if you want to run the clock at 240MHz
1333 at 250MHz
1800 at 270MHz
1866 at 280MHz
1600/2000 at 300MHz
