Windows 64-bit limits memory usage to 4GB.
Your system has more RAM than it appears, but Windows is limiting it to 6 GB. Restarting resolves the issue, though performance remains slow. Check for background processes or memory leaks that might be affecting speed.
I have an AMD FX 6300 CPU board with a Gigabyte GA-970A-DS3 GPU, Radeon HD 7850, and 1GB and 8GB RAM at 1600MHz. When I power on, it shows 6GB and 4GB RAM. After restarting, it displays 8GB RAM. I’m unsure if the issue recurs after a few restarts; yesterday it worked fine after a reset, but today it’s happening again.
When using resmon, check the memory section and see if the missing space is labeled "Hardware Reserved." If so, enable Memory Remapping in BIOS. Often the issue lies with the remapping being turned off or unsupported rather than a hardware problem. Another possibility is swapping RAM sticks temporarily to rule out a faulty stick.
Resmon displays the information: 6 GB installed. After restarting, the display updated to: 9 GB installed.
