What does it mean when your motherboard says it supports RAM at 1866/1600/1333/1066?

by on June 17, 2013

Q: When buying memory for your desktop, the speed of 2 sticks is 1866 for instance, and the motherboard can read something like, 1866/1600/1333/1066/ does this order mean that the first slot only reads 1866 and the second slot reads 1600? If so, does the second stick work in the 1600 slot at the 1866 speed, or does it only limit to 1600?

    The 1866/1600/1333/1066/ means that your motherboard will support RAM that runs at any of those speeds.

    For best results I suggest running two sticks of 1866 that were sold together as a pair.
