I've already installed 3x2GB 1333Mhz ram, is it possible to add another 4gb 1600Mhz?

I know it is safer and better if add another 2gb of 1333Mhz stick, but I want to know is it possible to mix-up ram of different speed?

Yes you can add but that RAM also runs @ 1333mhz ONLY .

Thanks for your response.

Do I have to set manually the speed or bios automatically set it?

My motherboard is Gigabyte B75M-D3H.

It'll do it by auto .

True, I already did it and it automatically set to 1333. what I did is withdraw 2gb 1333 from 3rd slot and put 1600. So I have 8gb now.
Running without any problem.

Thanks for your answer.
