Upgrading RAM in MacBook

cd02

I used the Crucial website and ordered 4gig of ram for my gf's macbook (which i've read it should be able to handle).

Anyways, ram turned up, installed and everything went well until after a week the macbook started freezing and getting the apple version of the blue screen of death.

So i took out the 4gig and put the 1gig back in and it appears to be working fine again.

Am i missing something simple with the upgrade or should i return it to crucual as faulty?

The macbook is a 2.1ghz white 13" macbook.

Try swapping the sticks of RAM around.

Also, make 100% sure that they are both seated correctly.

Cheers for that but was first thing i tried as i noticed they're not the most easiest things to slot it. Pushing harder to ensure they were clipping made no difference and swapping them appeared to make the macbook lock up quicker lol

If it is a white Macbook at 2.16GHz then it will only handle 3GB. Support for 4GB came in with the 2.2GHz Core 2 Duo machines that were on sale around 18 months ago. I have a 2.16GHz iMac which runs perfectly with a 1GB and 2GB module sourced from Crucial.

What happens if you run with just one of the 2GB modules? If you have a faulty module then it will show up which one. If neither is faulty then adding a 1GB module (or even one of the 512MB modules you took out) will give you a bit more.

Its the 2.1Ghz model, i used crucials downloadable thing and it said it could support 4gig and confirmed it with a couple of other ppl too.

I'll have to try them on their own then and see what that does.. only brought the 4gig as i always thought that running different sizes wasn't good and wanted enough ram to run sims 3 smoothly lol

Although it may only be able to address 3.3 GB of RAM, it should be possible to install 4 GB. This can give a very slight speed boost as the RAM will then be running in dual channel mode (provided each module is the same spec of course).

Testing each RAM module separately is a good idea though.
