RAM for Early 2008 Black MacBook won't work

[8vius]

I just bought 2x2GB PC2-6400 800Mhz chips for my MacBook. When I put them in, the computer won't boot up, it will light up the white LED but the screen will just stay black.

Even though that ram is not the Macbook's PC2-5300 kind, it should still be backwards compatible.

2008 MacBooks (MacBook 3,1 and 4,1) models will not start up with 2 PC6400 chips in them.....

They need at least one PC5300 stick - the other stick can be PC6400.

Whoever sold them them to you made a mistake. Return them and buy "proper" PC5300 i.e. avoid PNY.....

Really? That is a rather silly thing for them to do.

It's an apple thing. It just won't work.

If the company you bought the RAM from accepts returns then I would return them and find the right RAM that works for your MacBook.
