Do different types of RAM work with each other?

I have 2 sticks of 2gb XMS3 Corsair RAM @ 1333MHz and I just ordered 2 sticks of 4gb GSkill RAM @ 1600MHz. I have 4 RAM slots in my motherboard and was wondering if it would be a problem running all four sticks of RAM to get a total of 12gb RAM? I don't mind them all running at 1333MHz.

I must admit I've never tried it as the general rule is to fill all slots with RAM of the same type as there are differences in default timings which may cause issues in the different channels. Even if you were to manually set the RAM speed and timings to the same values in the BIOS there may be other variables that have an unknown effect. I use 4 sticks of 4 GB for a total of 16 GB but they are all the same type.

They seem to have the same timing on the box 9-9-9-24. Is there any harm in trying it?
