v1.40
853a675

Unofficial fork of ZenTimings by irusanov, with live sensor monitoring, memory benchmarks and OC tooling added. Auto-update is switched off on purpose — pulling an upstream release would overwrite everything below.

Built from 853a675, version 1.40.491.

Monitoring

  • Live CPU Die and DDR5 DIMM temperatures on the main window, each with a sparkline of its recent history and a min/max/avg tooltip
  • Total DIMM power, summed from the on-module PMICs
  • Tray icon can show the hottest temperature in a colour of your choice (Options → Tray icon colour), drawn at the shell's real icon size so it stays sharp on scaled displays
  • CSV telemetry logging
  • WHEA error monitoring

Timings

  • tCCD_L and tCCD_L_WR2, decoded from UMC registers that ZenStates-Core does not read: tCCD_L from 0x50198[7:3] + 5, tCCD_L_WR2 from 0x502E0[5:0] + 7
  • tCCD_L_WR, recovered from the APOB. It appears in no UMC register, and dumps differing only in it are byte-identical across both channel windows, the AOD table and the SPD. AGESA stores the three same-bank-group write timings as consecutive nCK values, one copy per channel, so it is located by anchoring on tCCD_L and tCCD_L_WR2 rather than on a fixed offset
  • CA / CK / CS on-die termination per bank group (ODT A and ODT B)
  • SPD-rated timings alongside the running ones, with per-timing tooltips
  • Timings panel rebalanced so all three columns end on the same row

Benchmarks

  • Memory bandwidth and latency tests with a dedicated results window
  • Persistent benchmark history and reference profile comparison

Overclocking

  • OC profile management and OC tools windows

Convenience

  • Turkish user interface (Options → Language)
  • Ctrl+Alt+S screenshot hotkey, named from the current memory configuration
  • Start with Windows
