Solution
Mixing RAM sticks of different timings may or may not work. Memory has a lot of other timings besides the MHz rating and if the memory controller cannot find a set of timings that both sets of modules supports then your computer may not boot or may act very weirdly.

Otherwise it may be that the different set work perfectly well together, in which case they will work at the highest speed supported by the slowest module. In your case this will be 1333.

is the voltage the same? You should always go for ram with pretty much identical specifications, if not this is what happens. It is preferable that you go for the same ram from same supplier. The latency is also a factor, and if that is different and again as listed above, won't work.

Get rid of your old stick and go for a new one, the same as your current 1600Mhz.
