Bitmain Antminer E9 E9pro Hashboard Test Fixture Repair Diagnostic Tool
A hashboard test fixture for the Antminer E9 and E9 Pro — Bitmain’s Ethash machines.
- What it does: powers an E9-family board on the bench, runs a test file from a TF card, and hands you the full fault log on a PC over USB-to-TTL
- Finds: dead ASICs, temperature-sensor faults, PIC faults, no-hashrate and low-hashrate conditions
- Narrow by design: E9 and E9 Pro boards only. An S19 / S21 bench wants the K3L or the universal tester instead
- Ask us first: whether the TF card ships with a current E9 test file — the fixture is close to useless without one, and we will not promise a card image we have not looked at
- Condition and warranty: not stated in this listing — ask and we will tell you what we actually have
Price:
$599.99
- Condition graded per unit: new, tested working, refurbished or as-is
- Warranty and returns stated per unit, not per store
- Ships UPS Ground within 7 business days
Description
A hashboard test fixture for the Antminer E9 and E9 Pro. It powers an E9-family hashboard on the bench, runs a test file loaded from a TF card, and reports what the board is doing — and over the USB-to-TTL link it hands you the full fault log on a PC, which is the part that actually shortens a repair. Beyond dead ASICs it is used to chase temperature sensor faults, PIC faults, no-hashrate and low-hashrate conditions.
Antminer E9 hashboard fixture — what it fits and what ships with it
| Fits | Antminer E9 and E9 Pro hashboards. That is the list |
|---|---|
| Does not fit | S19-, S21- or Whatsminer-family boards. If your inventory is S19s and S21s this fixture will sit on the shelf |
| Faults it chases | Dead ASICs, temperature sensor faults, PIC faults, no-hashrate and low-hashrate conditions |
| Fault log | Full log to a PC over the USB-to-TTL link — the part that actually shortens a repair |
| Test file | Loaded from a TF (microSD) card. Confirm with us whether a current E9 / E9 Pro test file is on the card — the files are distributed separately by the repair vendors and we will not promise a card image we have not looked at |
| Accessories in the listing photograph | TF card, two light-coloured signal cables, a 4-pin cable, a USB-to-TTL cable, a 12 V power adapter, an RJ45 network cable and a pair of red and black alligator power leads |
| The board it tests | Eight BM2280 BGA chips, each pair sharing a multi-phase supply; rails at VCORE 0.7 V, VP 0.9 V and VPH 1.2 V from the DC-DC stage plus VDDIO 1.8 V and VDDPLL 0.8 V from an LDO |
| Condition and warranty | Not stated in this listing, so nothing here claims either. Ask before you buy and we will tell you what we actually have — new sealed, opened, bench-tested or untested — and put any coverage in writing |
What ships with the Antminer E9 hashboard test fixture
The listing photograph shows the main fixture board with its heatsink, hashboard edge connectors and an Ethernet jack, plus the accessory set: a TF (microSD) card, two light-coloured signal cables, a 4-pin cable, a USB-to-TTL cable, a 12 V power adapter, an RJ45 network cable and a pair of red and black alligator power leads. That matches the accessory list the specialist repair vendors publish for this fixture — alligator power cables, a voltage regulation cable, a 12 V adapter cable, a USB-to-TTL cable and a network cable.
What an E9 hashboard actually is, if you have not had one apart
The E9 and E9 Pro are Bitmain’s Ethash machines — the E9 Pro is rated 3.68 GH/s at 2,200 W, about 0.598 J/MH, and was released in February 2023. Its hashboard is a different animal from a Bitcoin board: eight BM2280 BGA chips, with each pair of chips sharing a multi-phase supply, and rails at VCORE 0.7 V, VP 0.9 V, VPH 1.2 V from the DC-DC stage plus VDDIO 1.8 V and VDDPLL 0.8 V from an LDO. Eight big chips instead of a hundred small ones changes the economics of repair completely — one dead ASIC is a much larger share of the board, and getting the diagnosis right before you rework matters more, not less.
This is a narrow tool, and we would rather say so
It tests E9 and E9 Pro hashboards. That is the list. If your inventory is S19s and S21s, this is not the fixture you want and it will sit on the shelf — the K3L multi-function tester or the universal hashboard tester are the right buys, or the Whatsminer M20 / M30 fixture and the IceRiver KS fixture for those platforms. Buy this one because you hold E9 stock and post-Merge Ethash hardware is genuinely awkward to get serviced anywhere.
One thing to confirm with us rather than assume: whether the TF card ships with a current E9 / E9 Pro test file on it. The fixture is close to useless without the right test file, the files are distributed separately by the repair vendors, and we are not going to promise you a card image we have not looked at. Ask and we will check the card before it goes out. For the rework side, the full hashboard repair tool kit covers the bench; everything else is in repair parts and tools and on the miner list.
Condition and warranty
This listing does not state a condition grade or a warranty term, so we are not going to imply one. Before you buy, ask us and we will tell you what we actually have — new sealed, opened, bench-tested, or untested — and put any coverage in writing. Ask us about this unit.
What’s in the box
- 1 × Bitmain Antminer E9 E9pro Hashboard Test Fixture Repair Diagnostic
- Nothing that is not listed above. Cords, controllers, brackets and spares are only included when this listing names them — if you need to know before you pay, ask on +1 (781) 577-0377 or ns@ingmining.com and we will confirm in writing what is physically in the crate
Questions buyers ask about this part
Is this a complete, working machine?
No. This listing is on the parts and repair shelf, which holds both brand-new spares and bench tools and as-is units sold for repair. Which of those this one is, is stated in the description above — read it before you order, and ask us on +1 (781) 577-0377 or ns@ingmining.com if anything about compatibility with your fleet is unclear. We would rather answer the question than take a return.
What should I check the day it arrives?
Photograph the pallet or box before you open it, keep the packaging, and run the 48-hour acceptance test straight away. Freight claim windows are short, and a fault found on day two is a conversation while a fault found on day thirty is an argument. Our own six-step bench procedure is published in full, so you can repeat exactly what we did.
Shipping cost for this exact item, and how warranty and returns work here, are answered in the Shipping & buying tab on this page. Anything else, ask a person on +1 (781) 577-0377 or ns@ingmining.com — we would rather talk before you buy.
This is an E9-family fixture and nothing else — an S19 or S21 board will not seat in it. That specificity is the point rather than a limitation: the parts compatibility guide argues for matching a fixture to the hardware genuinely on your bench instead of to the longest coverage list, and for buying the diagnosis before you buy the part.

Where this listing sits
This one is on the parts and repair shelf. That shelf holds two different things: brand-new spares and bench tools, and as-is units sold for repair. Which of the two this listing is, is stated in its own description — read it before you order.
What our grades mean
These are the only words we use, and each one means a specific thing. They are not interchangeable and we do not soften them to move stock.
| New | Unused stock. Factory sealed unless the listing says otherwise — “new, open box” means exactly that, and the listing will say it. |
|---|---|
| Tested working | Second-hand, and it ran on our bench at the hashrate the listing states. We measured it; we are not repeating what the last owner told us. Expect cosmetic wear. |
| Refurbished | Tested working, plus work done: cleaned, thermal paste and fans dealt with, failed components replaced. The listing says what was actually done to that unit rather than using the word as decoration. |
| As-is / for parts | Sold with no working claim at all, at a price that reflects it. Buy these to repair or to harvest. If a listing says as-is, assume it does not hash until you have proved otherwise. |
| Untested | We have it, we have not powered it, and we are not going to pretend we did. Rarer than as-is and always stated explicitly. |
What a grade here does not mean
- Cosmetic wear is not a fault. Dust, scratches, scuffed labels and discoloured plastics are normal on hardware that has been earning. We photograph what we have; if the pictures matter to you, ask for more and we will take them.
- A grade is not a warranty. Warranty terms are stated per listing, never per store — see the Shipping & buying tab. A tested-working grade describes what the machine did on our bench, not what we owe you in six months.
- A boosted hashrate is not a spec. Where a unit ships on tuned firmware we say so and we give the factory figures too, because overclocking raises power faster than it raises hashrate — a tuned machine is less efficient per terahash than stock, not more.
- We will not invent a grade to fill a field. If a unit came in without history and has not been through the bench, its listing says that.
How the grade gets decided
A used-hardware seller who will not tell you how they test is asking you to take the grade on trust. Ours is published: the six-step bench procedure every machine goes through, and the five measurements that get recorded — per-board hashrate, chip count, measured wall power rather than the nameplate figure, hardware error rate, and temperature under sustained load. When it reaches you, run the 48-hour acceptance test straight away, while the freight claim window is still open.
Buying second-hand for the first time? How to buy a used ASIC miner without getting burned is the long version, written from the repair bench rather than from a spec sheet.
