ASIC Count on the Hash Board

ASIC chip compatibility table for Antminer hashboards helps you identify which chip marking belongs to your miner model before ordering parts, sending a board for repair, or comparing a failed ASIC chip found during diagnostics.

Different Antminer generations use different ASIC chip families, even when the miner names look similar. S19, S19j Pro, S19 XP, S19k Pro, S21, S21+, and S21 XP boards may all look like “19/21 series” equipment from the outside, but they do not use the same ASIC chips. Mixing BM1362, BM1366, BM1368, or BM1370 chips is not a shortcut. It is how expensive boards become educational material.

This guide is written for miners, hosting facilities, and repair customers who are searching for questions like “what ASIC chip does Antminer S21 use?”, “BM1370 chip compatible miners”, “Antminer S19 XP chip marking”, or “which hashboard uses BM2382AA?” If you need chip replacement add-ons, start with our ASIC chips collection. If you need diagnosis first, review our Antminer repair process.

Repair note: ASIC chip compatibility is only one part of hashboard repair. A missing chip count, 0 ASIC detected, unstable domains, sensor errors, or low hashrate can also be caused by LDO faults, signal-line problems, EEPROM issues, bad solder joints, power-domain shorts, thermal damage, or control-board communication problems.

ASIC Chip Guide by Antminer Series

Before using the full compatibility table, it helps to understand the main Antminer chip families. Bitmain model names can be confusing: S19, S19j Pro, S19 XP, S19k Pro, S21, S21+, S21 XP, L7, L9, KS5, KA3, and Z15 may all look like “just another hashboard repair” from the outside, but they use different ASIC chip markings, board layouts, algorithms, and diagnostic patterns.

Antminer 19 Series ASIC Chips

The Antminer 19 series includes S19, S19 Pro, S19j, S19j Pro, S19 XP, S19k Pro, T19, S19a, S19a Pro, and Hydro variants. These boards may use BM1398, BM1362, BM1366, or related chip families depending on the exact model and board revision. For exact chip replacement links, use the compatibility table below instead of guessing by miner name, because Bitmain naming conventions are apparently allergic to simplicity.

Antminer 21 Series ASIC Chips

The Antminer 21 series includes S21, S21 Hydro, T21, S21 Pro, S21+, S21 XP, and S21 XP Hydro. These models commonly use BM1368 or BM1370 chip families depending on the specific miner. If your S21 hashboard shows 0 ASIC detected, incorrect ASIC count, unstable domains, or overheating under load, chip marking is only one part of the diagnosis.

Antminer L-Series ASIC Chips

The Antminer L-series covers Scrypt miners such as L3+, L7, and L9. Antminer L7 boards are commonly associated with BM1489 / B20 chips, while Antminer L9 boards use BM1491AA. For Scrypt miner failures such as missing ASIC count, unstable hashrate, chain errors, or temperature faults, identify the chip first and then confirm the root cause through board-level diagnostics.

Altcoin Antminer ASIC Chips: KS, KA, K, Z, D, DR, E, and HS Series

Altcoin Antminers use algorithm-specific ASIC chip families. KS-series miners use Kaspa / kHeavyHash chips such as BM2380AA, BM2382AA, and BM2384BA. KA3 uses BM2110AA, Z15 uses BM1746AA, HS3 uses BM2130AA, and D7 uses BM1764AB. Use the table below to match chip markings to miners before ordering parts or sending the board for repair.

Antminer ASIC Chip Compatibility Table by Model

Use this table to match the ASIC chip marking to the Antminer model family. Some models have multiple board revisions, and some chip suffixes vary by production batch, so always confirm the marking on the actual chip before ordering parts or approving chip replacement.

Where a matching chip replacement page exists, the chip marking in the table links directly to that service. If a chip is listed without a link, use the ASIC chips collection or contact us with the miner model, board revision, chip marking, and kernel log.

How to Use This ASIC Chip Compatibility Table

1. Match the chip marking, not just the miner model

Do not rely only on the sticker on the case. Open the board, inspect the actual ASIC chip marking, and compare it with the table. Many Antminer model names have multiple board revisions, and the wrong chip suffix can waste time, money, and whatever optimism remained after the first kernel log.

2. Confirm whether the fault is really an ASIC chip

A failed chip can cause missing ASIC count, 0 ASIC detected, chain errors, low hashrate, unstable domains, or temperature sensor faults. But the same symptoms can also come from bad LDOs, damaged clock/reset lines, EEPROM mismatch, corroded connectors, cracked solder joints, or overheated board sections.

3. Use chip compatibility as a repair intake tool

If you are sending a hashboard for repair, include the miner model, board revision if visible, chip marking if readable, and the exact kernel log error. Useful examples include “chain X has 0 asic,” “failed to read hashboard,” “voltage init error,” “ASIC count mismatch,” “temp sensor read failed,” or “domain voltage abnormal.” For EEPROM-related failures, see our Antminer EEPROM repair service.

ASIC Chip Replacement and Hashboard Repair

Antminer Repair provides USA-based hashboard diagnostics and component-level repair for Antminer boards, including ASIC chip replacement when diagnostics confirm the failed chip is the root cause. We test repaired boards on dedicated diagnostic equipment and under real mining load before return shipment.

ASIC Chip Compatibility FAQ

What ASIC chip does the Antminer S21 hashboard use?
Antminer S21, S21 Hydro, T21, and S21 IMM hashboards are commonly associated with the BM1368 chip family, including BM1368PA, BM1368PB, BM1368AA, BM1368PV, and BM1368PM. Always confirm the marking on the actual ASIC chip before ordering parts or approving chip replacement.
What ASIC chip is used on Antminer S21+ and S21 XP hashboards?
Antminer S21+, S21 Pro, S21 XP, and S21 XP Hydro hashboards are commonly associated with BM1370-series chips, including BM1370BB, BM1370BC, BM1370AA, BM1370PA, BM1370PB, and BM1370PF.
What ASIC chip does the Antminer S19 XP hashboard use?
Antminer S19 XP, S19 XP Hydro, and S19e XP Hydro hashboards are commonly associated with BM1366AL and BM1366AG ASIC chip markings. Board revision still needs to be checked before chip-level repair.
Which ASIC chip is compatible with Antminer S19j Pro hashboards?
Antminer S19j Pro hashboards may use BM1362-series chips depending on the exact board revision. Common related markings include BM1362AA, BM1362AJ, BM1362AK, BM1362AI, BM1362AC, and BM1362BD across the S19j family.
What ASIC chip does the Antminer L7 hashboard use?
Antminer L7 hashboards are commonly associated with BM1489 / B20 ASIC chips. If the board shows missing ASICs, chain errors, or unstable hashrate, full diagnostics should be performed before replacing chips.
What ASIC chip does the Antminer L9 hashboard use?
Antminer L9 hashboards use BM1491AA ASIC chips. L9 failures often involve dense Scrypt-domain behavior, LDO issues, heat stress, missing chip count, or unstable chains, so chip replacement should follow board-level diagnostics.
What ASIC chip does the Antminer KS5 or KS5 Pro use?
Antminer KS5 and KS5 Pro hashboards are commonly associated with BM2382AA ASIC chips. KS-series failures may involve thermal behavior, sensor readings, domain instability, or chip-chain faults, so chip replacement should follow diagnostics.
Can I replace an ASIC chip just because the miner shows 0 ASIC detected?
Not safely. A 0 ASIC detected error can be caused by a bad ASIC chip, but it can also come from voltage-domain problems, LDO failure, EEPROM issues, damaged signal lines, cracked solder joints, bad connectors, or control-board communication faults.
Why does my Antminer S21 still show 0 ASIC after chip replacement?
If an Antminer S21 still shows 0 ASIC detected after chip replacement, the failed chip may not have been the root cause. The problem can also come from domain voltage, LDO output, clock or reset signal, EEPROM data, a bad solder joint, damaged signal traces, or communication failure between the hashboard and control board.
Why does my S19 XP hashboard detect only part of the ASIC chips?
Partial ASIC detection on an S19 XP hashboard can be caused by a failed BM1366-series chip, but it can also be caused by an interrupted signal chain, unstable domain voltage, temperature sensor issues, corrosion, bad rework, or a board revision mismatch. The actual chip marking and kernel log should be checked before replacing parts.
Can the wrong ASIC chip marking make a repaired hashboard unstable?
Yes. A chip that looks physically similar may not be compatible with the board revision, firmware expectations, voltage profile, or signal chain. Wrong chip selection can lead to missing ASIC count, unstable hashrate, domain errors, overheating, or a board that passes briefly and fails under real mining load.
Why does my L7 hashboard show chain errors even if the BM1489 chips look fine?
On Antminer L7 hashboards, chain errors are not always caused by a visibly damaged BM1489 chip. The issue may be related to power domains, solder fatigue, signal-line interruption, temperature readings, connectors, or previous repair work. Visual inspection alone is not enough to confirm chip failure.
Why does my KS5 hashboard overheat after ASIC chip repair?
A KS5 hashboard can overheat after chip repair if the thermal interface is uneven, heatsink pressure is wrong, a sensor reading is unstable, a repaired domain is drawing abnormal current, or one ASIC chip is not behaving correctly under load. Final validation should include real miner testing, not only a bench pass.
How do I identify the correct ASIC chip before sending a hashboard for repair?
Check the miner model, board revision, chip marking printed on the ASIC package, and the exact kernel log error. Photos of the hashboard and readable chip markings help confirm whether the board needs chip replacement, power-domain repair, EEPROM work, or deeper signal-line diagnostics.
Why does the same Antminer series sometimes use different ASIC chip markings?
Bitmain uses different board revisions, production batches, chip suffixes, and miner variants inside the same broad model family. That is why S19, S19j Pro, S19 XP, S21, S21+, and S21 XP boards must be identified by the actual chip marking, not just the case sticker.
