When Local Board Swap Voids Coverage—And When It Does Not

Operators ask us weekly whether swapping a hash board at their bench ends warranty. The answer depends on who sold the unit, whether firmware locks board IDs, and whether the reseller registered the farm.

Patterns we verified

• Gray-market batches — Often no local warranty regardless of swap location.
• Authorized reseller with registration — Board swap with matching OEM part number usually allowed; third-party boards void coverage.
• Mixed firmware — Some units reject boards until factory pairing; local swap impossible without tools operators should not use.

Documentation that protects you

Keep photos of serial stickers before opening, retain torque specs, and file reseller emails acknowledging local service. Our assessment reports include a warranty notes section per model—not legal advice, but a practical paper trail.

Mild reservation from the field

Policies shift when distributors merge. Re-verify before a large spare order; our parts sourcing review includes a warranty clause check when reseller documents are provided.
