Combining 1066 mhz ram with two 533 mhz ram

[0Lm91]

I actually have one ram of 2GB with 1066 MHz, and I would like to know if I can add another 2 sticks of 512 of ram, each one with 533 MHz, although these two and the other one have different voltage (the one of 1066 MHz 2.1 and the two of 533 MHz 1.7) to function in the indicated speeds. If this is possible I would like to know if the two sticks of 533 would work in dual channel if I use the one of 1066 MHz as well.

Thank you for reading.

Dual channel memory controllers will not run with three DIMMs. One, two or four DIMMs only. A single 2GB Dimm combined with two 512MB Dimms will not run in dual channel mode and if fact will not run at all on a dual channel memory controller as mentioned..
