Stop wondering where your miners are.
Bitmain-certified technicians repair your hashboards, and every step is tracked in one live system you can check from any phone, at any hour. No status emails to chase. No gaps between the shop floor and you.
Bitmain's S19 and S21 series are what we see most, and where we've built the deepest bench of parts and experience. If you're running something outside those lines, send it our way anyway — chances are we can still help, or point you somewhere that can.
Repair is easy to outsource. Uncertainty isn't.
The hardest part of sending miners out isn't the repair — it's not knowing what's happening while they're gone. We built our whole shop around removing that.
Answers when you actually need them
It's the middle of the night, you realize you need those miners back, and you have no idea what's happening with them. Text us status from the phone number on your account and you'll know where they stand in moments. Or open your portal from any device. No work computer, no waiting for business hours, no email chain.
Why it mattersDecisions about your site get made on real information, not on a callback tomorrow.
Every miner tracked, start to finish
Each miner is scanned in, then tracked through diagnosis, repair, a full 24-hour burn-in, and final QC, with a timestamp at every step.
Why it mattersYou can plan around when hashrate comes back instead of guessing.
One system, no gaps
Our technicians do the repair work in the same system you check. There's no separate "status update" someone has to remember to send. When a miner moves to burn-in, your view moves with it.
Why it mattersNothing gets lost in a handoff, and there's no lag between what's happening and what you're told.
A record you can point to
Pallets are scanned and recorded at the pallet level, and every unit carries a dated history from the moment it arrives.
Why it mattersInsurers and carriers want to know exactly what was on a pallet and when. It's the documentation behind a damage or loss claim, and what your own team needs for audits and warranty questions.
Certified hands on your boards
Every one of our technicians is Bitmain-certified, so your hashboards are worked on by people trained on this exact hardware. And now you can watch that work move through each stage instead of taking anyone's word for it.
Why it mattersSkilled repair plus visibility is the difference between trusting a vendor and verifying one.
Data you can put to work
Everything we track becomes something you can use, for planning, for budgeting, and for holding us accountable. It's built from the same live data our technicians work in, so nothing is re-typed or summarized by hand.
Live order status
How many miners are in diagnosis, repair, burn-in, or ready to ship, by text or in your portal, any time.
Why it mattersKnow what's coming back and when, so your site can plan around it.
Unit-by-unit history
A dated timeline for each miner: received, diagnosed, repaired, tested, shipped.
Why it mattersAnswer "what happened to this unit?" in seconds, and go into any warranty conversation with facts.
Quarterly summary
Miners repaired, average turnaround, and what was replaced across your fleet.
Why it mattersSpot repeat failures (recurring chip problems can point to heat, power, or airflow issues worth fixing at the site) and budget repairs from real numbers instead of estimates.
Warranty & DOA claims
Every claim we handle, what was done, and how it resolved.
Why it mattersFull visibility into the part of the relationship that matters most when something goes wrong.

Common problems we repair
Board-level work, not just a re-flash and a hope it holds.
Chip count issues
A board reporting fewer working ASIC chips than it should — dragging down effective hashrate even while the board still powers on and runs.
What this looks like in the logs
Bitmain's kernel log flags this as ERROR_ASIC_LOSS — its code for a chain that isn't reporting the chip count it should, usually shown alongside the actual per-chain number.
ERROR_ASIC_LOSS — Chain[2] chipnum=63
EEPROM errors
Corrupted or unreadable EEPROM data that keeps a board from being recognized properly — or at all — by the control board and firmware.
What this looks like in the logs
Logged as ERROR_EEPROM_INFO — Bitmain's code for when the stored board data (serial number, calibration values, chain info) can't be read correctly, often after an interrupted firmware flash or an aging EEPROM chip.
ERROR_EEPROM_INFO
Chain & hashing errors
One or more chains reporting unstable, zero, or dropping hashrate, including domains that fail intermittently after restart.
What this looks like in the logs
Often the same underlying flag as a chip-count problem — ERROR_ASIC_LOSS — just presenting differently: instead of a low chip count, the chain reports zero hashrate while the rest of the board keeps working.
ERROR_ASIC_LOSS — chain 3 hashrate 0
Power circuit faults
Blown LDOs, shorted components, and other power delivery damage that takes out a section of the board rather than the whole thing.
What this looks like in the logs
Bitmain logs this as ERROR_POWER_LOST — communication between the power supply and control board breaking down, showing up as abnormal voltage or a loss of power to one section of the board.
ERROR_POWER_LOST
Sensor & signal issues
Temperature sensors and signal lines reporting bad data, dropping out, or causing a board to be flagged as faulty when it isn't.
What this looks like in the logs
This is usually a direct, plainly-worded line in the kernel log rather than a coded error — the miner reports it outright when a sensor stops returning usable data.
Read temp sensor failed
Thermal & physical damage
Heat-stressed chips, damaged pads, and board-level burn damage — the kind of thing a lot of shops won't touch.
What this looks like in the logs
Heat damage doesn't always produce one clean line. More often it's a pattern — ERROR_FAN_LOST or repeated temperature warnings on the same chain in the log, right before that chain goes quiet for good.
ERROR_FAN_LOST (repeated, same chain)
From board details to a tested repair

Tell us what you've got
Board type, how many, and what you're seeing — chip counts, error codes, anything you've already tried.
We quote it
Standard or rush turnaround, quoted before anything ships, so there's no surprise once boards are in hand.
Request a quote ↓Board-level repair
Component-level rework — chips, EEPROM, power circuits, sensors — not a reflash and a guess.
Load-tested before it ships
Verified under load before it goes back, not just powered on and called done.
