Black Screen after upgrading my MacBook to 4Gb ram

[cybroman]

Hi everyone!

I have MacBook A1181 2007 model with Intel Core 2 duo 2,2Ghz processor, 1Gb ram and so on... Today i bought 2x2Gb Kingston DDR2 SO-DIMM 667Mhz ram. After i installed it MacBook turns on but it dosen't show nothing. If i put 2Gb and 512mb ram (2,5Gb) it works fine.

Where is the problem?

It might be that the RAM you have is DOA. If you got it from a reputable store they will replace with no hassle.

Or it could be the fact that it was not seated in the RAM bays correctly. You have to make sure you push it in till it goes click.

RAM is seated correctly but it still doesen't work. What means DOA?
What about this x2 ?

That's reassuring - just ordered 4GB myself. Went with a risky option of buying 800Mhz though!..

You might have faulty ram, get your 2 sticks replaced by the store you bought them from.

if i'm not mistaken (and i very might well be), your model doesn't support 4 gb of ram. my guess is the maximum is 3 gb (as it is with my 2006 mb) and as such your machine freaks out when you put in more than that.

Yes but if i combine first 2GB stick with 512mb stick or second 2Gb stick with 512mb stick it works.

Tried testing with both sticks? Ie first 2GB + 512MB and see what happens? Then second 2GB + 512MB and see what happens?

Hmm....i don't remember. I will try now and tell you if it works.
Thanks for all your help. I appreciate it.

This is info about my MacBook

Every combination works. Just 2x2Gb ram dosen't. That's why you can see that i have 2.5Gb rm because i am using 2Gb + 512mb right now.

In that case, I suspect your computer doesn't run 4GB of RAM. Which is very odd, if you have the model you say you do.

On the Black Macbook page... ' Maximum RAM: 4.0 GB*'

So probably this ram is not compactible with MacBook

Which RAM do you recommend?

Should this be ok?

I don't see anything wrong with that RAM

You bought incompatible SO-DIMMs. There are several threads on this topic.
