Yes, 4GB DIMMs are supported. You can use 5V DDR3 DIMMs running at 1066, 1200 and 1600 MHz.
1066 and 10660 are same modules i am asking about 10660 but u replied to 1066?
I am telling you speed in MHz. You can determine yourself what these other numbers are referring to.
i cant understand you just tell 10660 mhz works or not with this board
There is no such thing as 10660 MHz. This is a DDR3 rating number.
