How it works

Memory is measured using RSS (Resident Set Size), not virtual memory. RSS represents the actual physical RAM a process is using, though there's some inaccuracy when multiple processes share memory pages - the same memory can be counted more than once.

Also worth noting: modern operating systems want to use your RAM. If you have 48GB, you should expect most of it to be in use - that's the OS doing its job: caching files and keeping things fast.

Configuration

Create ~/.config/ramtousd.jsonc to customize pricing:

{
  // PCPartPicker DDR5 average
  "regularPricePerGB": 2.50,
  // Apple's memory upgrade pricing
  "applePricePerGB": 6.25,
  // Refresh interval in ms
  "refreshIntervalMs": 1000
}
