Optiplex 780 MT Ram Upgrade
I have a Optiplex 780 MT system and I has 4gb 1066mhz dual channel samsung memory.
I want to replace it with 2x 4gb 1333mhz dual channel memory kits, and I'm choosing between Zeppelin, Corsair, Patriot, and even HyperX.
My question is: will it work or do I need 1066mhz memory.
I know that there are a lot of posts on this forum with this topic, but none of them have a definitive answer.

4 memory slots =
White DIMM 1 (Channel A)
Black DIMM 3 (Channel B)
White DIMM 2 (Channel A)
Black DIMM 4 (Channel B)
Maximum = 16GB (4x4GB)
DDR3 = Non-ECC 1066MHz or Non-ECC 1333MHz (mixing will result in slower speed)
