Your PC isn't utilizing the full amount of RAM available.

I don't understand why this occurs but I tested two different dual rams and both faced the same issue. The image shows 8GB RAM, two 4GB sticks. Initially I thought the BIOS was the problem, then I upgraded the motherboard to support 16GB and it still didn't work. My PC specs: CPU Athlon ii x4 645, Motherboard MSI 880GM-E41, RAM juhor 4GB 1600MHz x2, Graphics gt 710. I believe the system needs around 4.5GB, and sometimes during games like Project Zomboid it caps at 4.5GB. When I had 6GB while playing Dota, it used nearly 5.6GB.
All programs consume the same memory size, regardless of system capacity. When memory runs low, the operating system uses the page file—essentially your hard drive acting as temporary storage—which is much slower than RAM. Increasing RAM won’t boost usage beyond what’s available, and switching programs changes their memory needs. That’s why a 64GB RAM PC isn’t faster than a 16GB one, even though it has more. I bought all the RAM, now I’m going to use every bit of it!
I thought it would be useful to note that certain games that heavily rely on RAM typically require around 4.5 GB. When I had 6 GB, performance dropped to about 5.6 GB during a Dota session.
