well, it should, but realistically, it sometimes just doesn't. 3200mhz and 3600mhz dont amount to a big difference in performance, or even price.
if its below a 10$ difference, get the 3600 and try it and hope for the best.
if its more than 10$ (lets say, 3200mhz is 100$, and 3600 is 120$) you should go for the 3200.
