Hello, It's rare for me to find a topic that is not covered on MDL having to do with PCs, but this seems to be one. I think the specifications that matter here are: 32GB RAM in 4 x 8GB sticks, dual channel. Windows 8.1 Pro operating system. HDDs, 2 x 2TB no RAID. No SSD. I don't have a page file. Oddly enough, when I got rid of my swap a few days ago, the amount of RAM went DOWN. It was sitting at about 4GB-4.2GB, and now the highest it goes is around 3.8GB. I'm sure triple channel would make the RAM utilized better, but of course that isn't an option. I searched around on MDL for some tips on how to get my OS to better utilize the RAM I have, but nothing came up. The computer takes about 5 mins or so to fully boot up, which certainly isn't a problem since I rarely need to reboot. However, general operation of the PC is not as fast as it could be. Starting up a Firefox session takes about 10 seconds. Loading up other programs takes about the same amount of time. My old computer build, which was an ancient 3.2Ghz Pentium D loaded much faster. How can I go about forcing my OS to use more RAM? Is the sluggish performance really just the result of using an HDD for my C: drive?
