MacinDoc said:That's assuming dual bank memory, as in the Power Mac. The iMac may not have the same architecture. It may, for example, have bus speeds only 1/4 of processor speeds, which would make dual bank memory unnecessary (the dual banks allow the memory access speed to more closely match the FSB speed). Such slower bus speeds would reduce the amount of heat generated, and would help to maintain the distinction between the Power Macs and the iMacs. Minimizing the number of RAM slots would encourage people to buy Apple's memory upgrades, at least for the 1st slot. Also, I don't think a prosumer machine needs more than 4 GB of RAM at this time (assuming the availability of 2 GB modules). Finally, fewer RAM slots would take up less space, which is likely to be at a premium in the new iMacs.
Of course, we don't want to return to the bad old days of having a 1.5 GHz chip with a pathetic 167 MHz buz, as with the G4. 🙄
Of course, if Apple goes with bus speeds at 1/2 of the processor speeds, then dual bank memory and 4 slots would make more sense.
Good theory, but there will be four slots because 64bit's main selling point is it's 4+GB memory access, otherwise they might as well keep it a G4, like now with the 2GB limit. The mother board will must likely be based on the low end G5, it is cheaper to do that, than have a totally unique bus ratio, memory requirements and what not.
In a nutshell if it needs to be in pairs it wil be 4 slots. and since all powermacs are dual now, there is no reason to put a smaller cache or slower buss, memory, in the Imac, as they have been inclined to do in the past, indeed they could duplicate 1.8-2.0-2.5 without stealing sales from the "Dual Powermacs". But I believe 1.4-1.6-1.8 with 2.0 being a maximum. 😕
