Ryzen CPU Power testing

AMD write support is experimental. Use this checklist to collect comparable results. Read-only telemetry is safe; writes require Enable experimental AMD writes and can be rejected or clamped by firmware.

Always keep the charger connected for Stages 0–3. Only test battery-mode writes after AC writes are confirmed to work and read back correctly.

Before testing

AMD Framework laptop/desktop (supported families: Raven, Renoir, Mobile/Phoenix, Strix Point/Krackan, Strix Halo, Raphael/Granite Ridge/Dragon Range).
Framework Crate 0.9.6 or newer, run as administrator.
PawnIO + RyzenSMU.bin installed via Download Modules, then Redetect.
HWiNFO64 in Sensors-only mode (for package power cross-checks).
CPU-Z for the all-core load (Tools → Stress CPU).
Keep %APPDATA%\framework-crate\app.log available for the report.

Stage 0 — read-only

AMD CPU Power card with Copy diagnostics — AMD CPU Power card — Copy diagnostics is at the bottom of the settings area.

Open CPU Power. Confirm the card says AMD RyzenSMU.
Press Copy diagnostics and keep the output.
Check that code_name, smu_version, pm_table_version, STAPM/PPT Fast/PPT Slow, Tctl, and APU Slow look plausible (not zero or absurd).
Compare with HWiNFO64 idle package power and any PPT limit row.
Report the diagnostics through the AMD issue template.

Stage 1 — no-op apply

Enable experimental AMD writes.
Apply the same values that are currently shown.
Confirm the command succeeds and the PM-table readback is unchanged.
If it fails, stop and report the error text + diagnostics.

Stage 2 — small delta + readback

On AC power, lower STAPM/PPT Fast/PPT Slow by 5W (or Tctl by 2°C); keep everything else.
Press Apply and confirm the readback matches the request within 1W/1°C.
On AC, run CPU-Z Stress CPU and record HWiNFO64 package power.
Press Reset and confirm the captured baseline comes back.
Report both the requested values and the readback/HWiNFO results.

Stage 3 — profiles, keep-alive, transitions

Only run this stage after Stage 1 (no-op) and Stage 2 (small delta) both succeeded with a matching readback. If either fails, stop at Stage 2 and report; do not enable keep-alive or test sleep/AC transitions until a write is confirmed working.

On AC, save the AC profile and enable keep-alive; confirm the AC profile applies.
Only then save a distinct Battery profile and verify the switch after unplug/replug.
On AC, sleep/resume and verify the profile is re-applied.
Repeat once after Reset (keep-alive should turn off).
Record any unexpected value, error, or fan behavior and the power source used.

Reporting

Use the AMD CPU Power test report issue template and include:

diagnostics from every stage
exact values requested and read back
HWiNFO64 package power before/after (CSV/screenshot if possible)
a screenshot of CPU-Z Stress CPU running alongside HWiNFO64
sleep/resume and AC/battery observations
relevant app.log lines

Do not include serial numbers, tokens, or other private data. If a write fails or the machine behaves unexpectedly, press Reset, disable the experimental toggle, and report before trying again.
