This depends on the virtual memory hardware of the CPU chip in question. It's not the case for any of the most recent Intel chips. (I'm very unfamiliar with AMD's processors, so I can't remark on their characteristics.) > Does that only hold true for M$ or are all PCs the same? How > does one get more than 4GB onto a mobo? Do the new ones > allow that? Buy a system designed for, say, the Core 2 processor series and you can put far more than 4 GB. For almost any practical (desktop) purpose the RAM capacity is unlimited. The limits come from the number of RAM slots and kind of RAM supported by the mainboard. > Curious Note that Crucial (a RAM vendor) has announced DDR3 RAM modules and that mainboard vendors are starting to accommodate this standard, so the capacity and speed limits continue to increase.
