Memory problems?

I have the memory is 512mb ddr533, is now selling a 1Gddr2 667, and the two together can not use.Inserted in the board's two-channel with a different color or colors

…is a ddr a few of the ddr2 is your memory is in the end DDR533 or DDR2 533.

if your motherboard using DDR2 533 memory, dual-channel to start But the 667 will be reduced to 533 to use!
you that there is no problem, the premise is not compatible with memory problems! Oh, can not be used, the models are not the same, even if the same is also not the best, together with the wrong bar, ddr533 is the ddr1? Are now 2.However, dual-channel can not be opened for.
