Wait, something's not right.
DDR3 RAM should be either 1066, 1333, or 1600, but yours is 667MHz. Did you get that 667MHz from the product manual / spec sheet or you got that from BIOS?
If it's from BIOS, get DDR3 1333 SO-DIMM because that's proly 1333 / 2 (for dual channel) = 667MHz per channel. Also 10700 / 8 is 1337.5, approx 1333. But that's just my guess.
The best thing to do is look at the product specs on laptop maker's website. But you didn't mention the make and model so, I can't do that right now.
