RAM vs FSB

DMA > Direct Memory Access

http://en.wikipedia.org/wiki/Direct_memory_access

All systems can use the direct memory access channel. Although, I expect each system might be different in that the DMA is likely configured through the system BIOS. Or that, you'll see from within system properties the channel, and how it is addressed in relation to memory buffers and the like once you know the channel number. The link above explains the characteristics of DMA, and as such, RAM that exceeds the speed of the FSB is not always an issue. Although, it is a given that the most significant issue is whereby the CPU and FSB onboard must be set to the corrected overclock speed to work with the faster memory. In some instances the Hyper transport protocol may still yet need to be recognized varying upon the type of graphics card in use and how Vista handles such calls. FSB Overclock

Perhaps the next service pack for Vista, if not the one that was just released will serve to resolve the amount of memory Vista is able to initialize.

I wonder if Vista is only limited now by the introduction of such programming modules as Direct X? But, it should however, always recognize virtual memory paths and settings.
