1. Overview TestMem5 (TM5) is a lightweight, high-stress memory testing utility originally developed by Serj. Unlike general-purpose tools like MemTest86, TM5 is designed for rapid error detection under heavy, real-world loads. It is the preferred tool among memory overclockers for validating timings, voltages, and frequency.
| Test # | Primary Target | What it stresses | |--------|----------------|------------------| | 1–3 | Basic read/write | Row activation, tRCD, tRP | | 4–6 | Random access | tRC, tRFC, bank group conflicts (DDR5) | | 7–9 | Heavy writes | tWR, tRTP, tWL | | 10–12 | Mixed stress | tFAW, tRRD, power delivery | | 13–15 | Thermal soak | Temperature-dependent leakage |
