Whats the difference?
I am pretty sure both are compatible with the macbook. I think.
 
DDR3 1066 is 8500 memory. What you need to be sure is that you are getting 204 pin DDR 3 RAM.

8500 is the naming convention, whereas 1066 is the actual speed. 1066*8 ~ 8500.

1066 DDR is 533 Megahertz RAM with two transfer cycles per clock for an effective clock rate of 1066 Megahertz.
 
10666 memory didn't work in my MacBook (Late 2008). I had to return it to New Egg for the 8500 speed.

Hope this saves everyone time.

2.4Ghz 2GB of ram...wondering if this model supports the 240-Pin PC3 8500 RAM sticks?????

so i just went ahead and ordered the regular PC2-5300 RAM (4GB kit)...

Your macbook only supports 200 Pin DDR2 667 Mhz RAM.

The new MB/MBP only support 204 Pin DDR3 1066 Mhz RAM.
