Hi, i recently upgraded my laptop's RAM (i3 4030u on Windows 8.1) from 4GB to 8GB not that much because i needed additional memory but in order to enable the dual-channel. Now i see that my RAM usage hovers around 55% = more than 100% of previous usage, while when i was on 4GB. Back then it would rarely go above 60% RAM usage except in games. How to explain that, is it a good sign for the system that additional ressources have been allocated? Thank you.
