Yes, it will work.

According to this Apple page your machine supports up to 2 GB. It doesn't matter which slot you use.

guys,

i wanted to boost my sister's MB (the newest version) so i ordered a 1GB RAM from newegg. thing is that i thought the MB was similar to my MBP and originally had 1X1GB inside (one slot is empty.) but it turned out that the MB has 2X512Mb , which leads to the question: should i replace one of the 512 ones with the 1GB i just bought anyway, or they have to be equally paired (either 2X512 or 2X1GB)?

thanks a lot!

The MacBooks have always shipped with two modules because it improves performance, particularly for the graphics card. Upgrading to 1GB+512MB will work fine, but it will incur a hit in graphics performance.

You need the one on the top: 667MHz PC2 5300. The bottom one will not work in your MB.

I put 2 2GB PQI DIMMS in my MacBook Pro 2.4GHZ, and it runs like a charm. The RAM modules had the same logo as the Apple ones I pulled out of the computer.

I think in general, the cheaper Taiwanese RAM companies like Transcend and PQI are very good. you have to realize that Kingston and Crucial are just re-branding the same RAM that PQI are selling. It's just closer to the source if you get the Taiwanese, that's why it's cheaper -- one less middle man.

Am I smoking crack? When did MBP ram drop so much in price? OWC has a 4GB(2x2GB) for $95, plus $20 rebate if you send in your 2GB(2x1GB). So $75... or $107 for the 4GB kit from Crucial. I almost feel like I'm robbing someone at that price. 4GB for under $100?

No crack. You just have to be on your toes sometimes. RAM prices can be stuck in a rut or really volatile. Which is of course when you need to pay attention on a fairly frequent basis and pounce on deals when they show up. My purchase of 2X2GB for a total of about $70 after rebate is beginning to sound like it's a bit pricey, and that was only about a month ago.

2GB DDR2 SO-DIMM prices cratered about a half year ago; there's currently a huge glut in the DRAM market and a few OEMs are going to move their laptops to 2x2GB base this quarter.
Newegg has 2x2GB for $70 with no exchange/rebate nonsense (save another $5 if you want to do a mail-in rebate), so you can keep your 2x1GB or eBay it or make keychains out of it or whatever.

Nope. It's just a great time to buy RAM right now.

I managed to find 2x2GB Kingston SO-DIMM for $90 in Europe. Now I just need to find out how to make earrings out of those 1 GB sticks.

OWC has a very good reputation. They're not the cheapest, but quality is just fine. Enjoy your loaded MBP.

Not totally true. I have a MacBook Pro 2.16 GHZ Core 2 Dual with 1GB DDR2 667 MHZ ram in 1 slot and the other empty. Got it from Apple.

I prefer either crucial or OWC.
I'm a big believer in that you get what you pay for and while I don't want to pay apple prices for thier memory. Crucial and OWC offer high quality ram with a lifetime guarantee and top notch support.
