Does ReadyBoost take away from your addressable memory map?

[Obsoleet]

Just as the question states 🙂 GPU memory does, so I'm wondering how ReadyBoost is used in Windows. I'm on Vista32

it has nothing to do with the address space, readyboost is like a faster page file.
the idea is that USB flash is faster than your HD, therefore more suitable for paging file allocation.

search the articles around the time Vista was released to find an article about readyboost.

Are you referring to superfetch?

If so, no superfetch doesnt actually take away from the addressable map.

I believe as of Vista SP1, graphics cards wont either.

I think he's asking if you add a 1GB USB drive for ReadyBoost, for example, does that 1GB get mapped into the same range as system memory, thus reducing the available mappings for other devices/memory. Not sure.

Keep in mind that it basically gives no performance gain above 1GB of physical RAM.
