RAM Calculators & Tools

Sensible pagefile (virtual memory) sizes for your amount of RAM — and why disabling the pagefile is a bad idea.

Convert between real clock (MHz), effective transfer rate (MT/s) and clock cycle time — and end the 3000 vs 6000 confusion.

Turn a full timing string (CL-tRCD-tRP-tRAS) at any speed into real nanoseconds for every primary timing.

Theoretical memory bandwidth from speed and channel count — the number that explains single vs dual channel.

Compare two kits side by side: effective speed, true latency and dual-channel bandwidth in one view.

Convert any kit’s CAS latency and speed into true latency in nanoseconds — and compare two kits head to head.

Answer five questions about your PC or laptop and get a plain verdict: what RAM generation, form factor, capacity and speed to buy.
