I don't know what's the mean of "KIT" at some online store of memory, when I want to update my memory of macbook.
Could somebody give me some idea?
Ok, thank you guys.
But two single 1GB memory will be cheaper than one 2BG kits. Is that weird?
That is the matched pair tax.
'matched pair tax'? What a strange tax. I have never **** sound that.
It is a saying that I kinda made up on the fly. Kinda like the mythical Apple Tax. Or the "Insert brand name Here" Tax. The matched Pairs tax was really obvious when having memory operate in dual channel mode was more desirable than not. So manufacturers would package memory modules as matched pairs. It also ensured that the overclockability (the other people who cared about the quality of thier ram) was the same between modules.
With Apple systems the only thing you really should worry about is that the memory modules are quality modules. Matched pair isn't as important anymore. Especially since Apples latest systems can't be overclocked (as far as I can tell).
Thank you! But I still don't understand.
1.What you mean is that the pair is different with two single one which is totally the same?
2. Did you mean that apple don't operate in dual channel mode?

1) I don't think their is a difference, at least in the real world. Two modules of the same part number should work just fine. Matched pairs seems to be little more than marketing and paying a 'tax' for intangible 'peace of mind'
2) Many macs (maybe all current?) are able to use dual channel mode. Dual channel doesn't specifically have to do with overclocking, and certainly isn't reliant on it. (It sounds to me they were thinking of ECC error checking, which is more expensive and needed for over-clocking. Since macs don't allow for ram over-clocking, then its fine to get non-ECC ram)
Edit: diamond.g is correct. I was a little off about the ECC comments - that's not what he was talking about.
