Enable Memory Remap on Vista x64 with on 2 gigs?

[Uninvited Guest]

Is there any benefit to enabling the memory remap feture if I only have 2 gigs of ram? In my bios, the description of this feature says that it improves memory utilization. All I know that this feature does it lets the OS detect more than 3.2 GB of ram.

Thanks.

The memory mapped IO takes up some of the physical address space. The memory remap function was invented so the MMIO space and RAM wouldn't overlap. So unless MMIO in your machine takes up more than 2GB then it will have no effect.

If you had 4GB installed, and MMIO takes, lets say, 0.75GB, the remap function would take the last GB and hoist it up above the 4GB-boundary.
