I'm putting in a new stick of memory for my laptop, and can get a higher speed stick than the first one. However, I want to do dual channel memory. Is there any downside at all to having a 1333 stick and a 1600 stick vs just two 1333s if I'm dual channeling my memory?

1600 stick will just run at 1333. Its always better to just buy a new pair so timings match, you may be causing more issues by mix-matching the ram sticks.

First post. But the difference between 1333 and 1600 won't be anything drastic. Do whatever is cheaper IMO.

Yeah but I already have the one 1333 and don't think the speed benefit would be much to buy two 1600s, for example. Just wasn't sure if a mixed combo would be worse than two lesser equals

IF everything else is the same except the speed, probably not a big deal. If the brands are different, timings different, etc... (and obviously the correct pin count), I would buy a pair.

Does your computer chipset support the higher bus speed?  Just swapping out memory sticks won't do anything other than give you more memory (provided they are larger RAM to begin with).

I think so. It's a laptop so I'm having a hard time pinning down the mobo specifics, but what I'm looking at is still ddr-3

You cause bigger problems by mixing memory stick sizes.

Many systems will default to the smallest size for all sticks installed.  You can have a 1Gig stick and an 8Gig stick in your machine, but it will run like it's got 2 1Gig sticks because it's ignoring everything above 1Gig on the larger capacity stick.

You need to refer to the motherboard manual to research exactly what your machine will do if you start mixing memory sizes and speeds.  I've seen seen cases where mixing brands of same size and speed memory sticks can cause problems.
