    I'm looking to upgrade the RAM in my iMac G5. I have 2x256 right now. My plan is to start with 1x1GB then add another 1GB later. What should I get? Is it worth the extra money to get the 2 CAS latency? What about timings? Brands?

    Give a search thorugh the forums for Memory.

    The CAS latency in general will not make a difference. There has only been one report of a difference in performance with lower latency, and the method of testing was flawed. Apple has never indicated tht their motherboards can take advantage of faster RAM timings.

    The iMac is the most finicky recent Mac about memory compatibility
    PC generic PC3200 RAM may or may not work -- unless the Serial Presence Detect settings are correct, it will probably fail in the iMac.

    You are looking for a reputable seller who tests and guarantees compatibility with your specific model Mac, in writing, and offers a lifetime warranty and a no-cost return if it doesn't work (no restock fees). This would rule out most eBay sellers, big-box stores and online discounters.

    MR readers variously have recommended Crucial, OWC and Data Memory Systems as good sellers in the USA.
