    I ordered 1 GB of G.SKILL RAM on Newegg for $99. :) I plan on removing one 256 MB stick and replacing it with a 1GB stick. It is possible to run the Macbook without matching sticks, correct?

    Yes, but performance will suffer. When you have matched pairs installed, you effectively double the throughput from the RAM to the memory controller. This really makes a difference on the MacBook due to the integrated graphics.

    Whoa how'd you get 1GB G.Skill RAM for $99? Anyways, matching pair would out perform than not matching.

    running it now.

    when i upgraded from 512 to 1.25 total ram..i noticed SIGNIFICANT changes..everything runs a lot smoother / takes less bounces to load etc.

    i wouldn't go back..thinking up adding up to 2gb.

    while yes matching sticks ARE best and recommended..using 1.25 has been working out fine for me so far.

    i got the kingston stick btw.

    Running same setup, but with Patriots, no problems here.

    Bought the 1GB of G.Skill from NewEgg back in late June, and I've been running it without problems at 1.25GB since. While it's true there's a bit of a performance hit when running unmatched sticks, the fact that you have 768MB more of memory far outweighs it.

    Also, $99 for 1GB is cheap? When I purchased back in June, the stick of G.Skill DDR2-667 (1GB) cost me $80....

    I got mine for $85 from Frys B&M a little over 1 month ago. All the prices were under $100 for sure when I went.

    My Dad's Macbook is running at 1.25GB. It was a significant improvement. Although matched is best, 1.25GB is better than stock 512MB. His was OCZ. Cheers

    but the extra 256MB will be more beneficial than two 512MB sticks.

    Replacing one of the stock sticks with a gig would be cheaper, it would allow more future expansion options, and it's faster than 2*512MB.

    Go for the 256MB+1GB option. It works brilliantly for me :)

    Zactly. Also going for one 1 GB stick and another 256 MB will allow you to easily max out the RAM to 2 GB (whenever it becomes financially possible for you) without worrying to discard the 2*512MB chips.

    There was a link on somewhere on macrumors that showed a match pair of 512 outperformed the 1.25 combo. Now I just have to find the link. :D

    Edit: Just read it over again, and it basically said not to expect large gains by using matched pairs.
