Using Speccy 1.25 under Windows Vista Home Premium on a HP Compaq Presario 4000, the "summary" page incorrectly reports '2 GB' of RAM, while the "RAM" page correctly reports '1.5 GB' of RAM (one 1GB stick and one 512MB stick).
Is the "summary" page rounding-off all the "fractional" megabytes, e.g., 1.25 -> 1.0 and/or 1.5 -> 2.0 ?
