Memory matching question

[redrider4life4]

So I have 2x2 gb of OCZ DDR3 1600 memory, but my board/cpu is capable of triple channel. I was going to add a 3rd stick of the below so I'll have 3 x 2gb = 6gb total. Is it a good idea to mix and match brands? Both are DDR 1600 memory running at 1.65v with 9-9-9-24 timings. It will only cost me $15, I really just need an additional 2gb of ram, but figured triple channel would be cool while I'm at it.
