A quiet checklist for hashrate drift after the first week

New shelves rarely sit perfectly still. Dust begins to settle, pads compress slightly, and room temperature shifts between day and night. Distinguishing normal variance from a failing riser saves both panic and unnecessary part swaps.

Capture a baseline on day one

Write average hashrate, board power, and hotspot readings after the first stable hour. Without that page, “drift” is only a feeling. Fundamentals learners fill this into the home start-up checklist before they leave the lab.

Stop-and-check symptoms

One card consistently 15% below its siblings, repeated miner restarts on a single slot, or a sudden watt climb without a tune change — those earn a pause. Power down, reseat the riser, inspect the cable, and only then chase software settings.

Normal noise

Small day/night swings tied to room temperature, or a brief dip while a window was open, usually do not justify a full tear-down. Compare against your worksheet before ordering replacement pads or a new PSU.

If logs still look odd after the checklist, a Private Mentoring Block can walk through your numbers with an instructor.
