The only thing installing 800MHz RAM in your MacBook would do is force it to run at 667MHz. Why waste your money? And for the love of all that is good in this world, do a little research next time. A simple search or even a visit to the Guides section would have given you an answer without having to wait for replies to your threads...

800Mhz DDR2 200-pin SDRAM which I can PROVE it works in the 2.0Ghz White nVidia Macbook of early 2009...
And for UK customers...

I have the same model Macbook, and I installed 2x2GB of 800Mhz DDR2 RAM this morning and it runs perfectly well at that speed.
The nVidia chipset allows it to run at this speed, along with the 1066Mhz FSB. (I think)
I though the same, but the guide does mention 800Mhz RAM working in the late 2008 white Macbooks.

I stand corrected. I was unaware of the compatibility with the nVidia models but was going on my knowledge of previous models.
