    Is there any performace gain when you install identical pairs of DIMMs in the new iMac?

    Since I have the standard 1gb variety, should I install another 1gb module, or, if performance isn't an issue, install directly a 2gb DIMM?

    Many thanks,

    Performance gain with paired ram is minimal, don't let it influence your decision.

    I agree with this, dual channel broke on my PC and it wouldn't boot up unless it was set at single channel and there was little to no difference in performance.

    But it this way a system with 3GB unpaired with outperform a system with 2GB paired.

    Since the santa rosa platforum it doesn't mather if those dimm modules are the same, speed is equal. But if you don't have a SR machine, like the macbook pro 2.33, you get some speed increasment with identically pairs of memory modules.

    Why does it not matter in a SR platform, doesn't it still use Dual-Channel like Napa and therefore benefits from having matching pairs ?
