    667 DDR2 PC2-5300



    I got mine from crucial



    edit: also it's a very good idea to fill both ram slots with matching pairs like,



    [1 gig] [1 gig]



    or



    [512] [512]



    etc...

    Just ordered a 2GB kit (2 x 1GB) from powerlinememory.com for $158. It's cheap, generic memory. My fingers will be crossed that there are no problems.



    I've bought from Crucial in the past. They have a good reputation for quality memory but this time they want more than twice as much money, so I'm taking a chance with the cheap stuff. Chances are it'll work just fine.

    how about using 1gb + 256mb (the one installed)



    will the performance worse than 512 + 512 mb?



    because I really don't want to buy both 512 and in case i want to upgrade in the future.



    So just buy 1 gb and leave 256 there. What's ur opinion?

    Matching the memory is related to graphics performance, not OS performance, because it is integrated. I do not know what type of performance hit you will take by not having matching RAM so hopefully, someone else will have that information.



    If you are buying online from Apple spend the extra $100.00 to get 2x512MB memory modules because you will double the memory and it will be matched. While you are using your MacBook with 1GB RAM you can decide whether you really need 2GB RAM. If you are buying from a retail store then use the MacBook with the stock 512MB RAM until you can get 2x1GB modules at the same time so you are sure that the two modules have the same make, model, latency, etc.

    Got and installed 2GB today. It passed the Apple (extended) Hardware Test. No problems so far.

    About a week. They ship ground for free.

    I might be wrong, but does it void Applecare to remove all apple-official RAM?



    And also, does anybody really know the performance hit between matched pair or no?

    Will jacking up the ram to 2GB+ have any effect on the integrated chip's ability to handle 3D rendering in things like games? I heard that the MacBooks won't be able to handle anything newer than say World of Warcraft without a serious hit in the FPS department.

    It's doesn't void the warranty, except for the ram.

    Someone please correct me if I'm wrong: Don't the MacBooks and iMacs use the same RAM?



    If so, my plan is to buy a 512MB stick and a 1GB stick. Put the 512MB from the iMac & the purchased stick in a MacBook; put the 1GB in the iMac. Add another Gig to the iMac as needed.



    - Jasen.

    No, it's not the same.

    Oh yes, it is.



    By the way:

    Does anybody know, whether 2x 512MB (=1GB) (Dual Channel) is faster than 256MB+1024MB (=1,25GB) (No Dual Channel)?

    When you look at prices of 1GB sticks at Crucial for the MacBook vs. the current DDR2 iMac, while the specs appear to be the same, the prices are different. Hmmm. Do they both use small laptop size memory sticks?

    I paid 930 Hong Kong Dollars per stick... so yes it was expensive but I wanted it there and then!

    Same as I - the Corsair one's - Value Select but they only had 1 stick left! ( so I went upstairs and bought it for 930.

    Dual Channel = faster. Without Dual Channel (IIRC), the Intel graphics chip will have limited access the main memory. So even if you have 1.5GB (1GB stick + 512GB stick) the memory available to the GMA950 would only be 64MB (I think).
