Macbook Mid 2009 - compatible with DDR2 667 laptop memory?

[KSBOOM]

For the Mbook Mid 2009 model (Rev. H), in the tech specifications it says it supports 800 MHz DDR2 SDRAM. However, I have 2 sticks of DDR-667 SDRAM lying around so I wouldn't mind using those if I can. Would the Mbook Mid 2009 work with DDR2-667 SDRAM?

Thank you.

It may, it may not. Really, it depends on the quality of the 667mhz DIMMs. Really though, 800mhz DDR2 is very very cheap, just buy some proper DIMMs to avoid any issues.
