All 64-bit components?
Is there a motherboard that uses all 64-bit capable components? Seems that only the CPU can switch mode between 32-bit and 64-bit... -- @~@ Might, Courage, Vision, SINCERITY. / v \ Simplicity is Beauty!

'64bit', in relation to the processor, is referring to the _address range_supported. The 'width' of the data bus, has nothing to do with this, and on most motherboards, is already larger than this (most systems using 'dual banked' memory, are handling a 128bit data bus already). There is no such 'thing' as a 64bit capable component, in these terms, unless you had a single memory chip, which had an address bus larger than 4GB. The whole 'point' of the larger address space, is that the total memory spaces needed by the modern system, has (on larger systems), been more than 4GB for quite a time, and the 64bit processor, when combined with a 64bit OS, allows these to be used, without having to resort t 'bank switching' approaches. Think of it like a library. The 64bit systems, allow more volumes to be addressed, but doesn't itself affect how large the volumes 'are'. Best Wishes |

Real-time database could be possible with more RAM... -- @~@ Might, Courage, Vision, SINCERITY. / v \ Simplicity is Beauty!
