That is normal if the integrated video is active and allocating a slice of the main RAM pool for itself.

IBM designed the original PC to use memory addresses between 640mb and 1gb for hardware access and it is therefore not available for operating system use. It's just part of windows. Don't worry about it. Any memory you add in the future will show up just fine.

Windows Experience Index is not a very good judge of system performance. Microsoft changes it as hardware gets more powerful. What was your old system spec?
