Back to running Windows-7-pro. Still more solid than 8.1 or beta-10. I have 16-gigs of ram on the board. Windows-7 sees it, but I often wondered if it actually uses it. I had the pagefile at 12-gigs. So I did a test. I moved 38-gigs from one sata drive to another sata drive. The desktop gadget All_CPU_Meter_V4.7.2 showed ram at 14%, and pagefile at 16%. Windows-7 wants at least 1.6-gig pagfile. So I "customed" the pagfile to 2-gigs, low and high. Rebooted and tried another test. I moved 55-gigs from one sata drive to another. Pagfile went up to 18%, BUT ram went up to 26%..! Am I wrong in this observation as to how make more use of the ram on the board........?
