Indice de fiabilité et modes de défaillance des ASIC — ce qui tombe réellement en panne (données gratuites)
Voici l’indice de fiabilité et des modes de défaillance des ASIC : une ventilation structurée, modèle par modèle, de ce qui tombe réellement en panne sur les mineurs ASIC Bitcoin et leurs blocs d’alimentation, bâtie entièrement à partir de sources publiques et notée selon la solidité de cette preuve. C’est la couche de données derrière le texte — au lieu de « le S17 n’est pas fiable », vous obtenez le composant précis, le mode de défaillance rapporté, sa fréquence dans les rapports publics et le nombre de sources indépendantes qui le corroborent.
Chaque entrée ici est une expérience communautaire rapportée, et non un taux de défaillance interne de D-Central. Lisez l’avis de provenance ci-dessous avant de citer quoi que ce soit, et consultez notre page Fiabilité et méthodologie des données de minage pour les règles de sourçage complètes. L’ensemble de l’indice est téléchargeable gratuitement en CSV et JSON sous licence CC BY 4.0, et chaque modèle renvoie directement au service de réparation D-Central correspondant.
Réponse rapide
L’Index de fiabilité / modes de défaillance ASIC de D-Central détaille ce qui tombe réellement en panne sur 30 mineurs ASIC Bitcoin et blocs d’alimentation — 102 familles de défaillances de composants réparties entre cartes de hachage, domaines d’alimentation, ventilateurs, cartes de contrôle et alimentations. Chaque entrée est notée A/B/C selon la solidité des sources et étiquetée selon la fréquence à laquelle elle est signalée dans les sources publiques, jamais selon un taux de défaillance mesuré.
La défaillance la plus signalée sur l’ensemble du parc est la mort en chaîne : une seule puce morte ou une soudure froide met toute la carte de hachage hors service. Téléchargement gratuit en CSV et JSON.
Les six axes de recherche
- Forum — fils Reddit / BitcoinTalk (BitcoinTalk et GitHub sont les sources primaires citables)
- Démontage — chaînes YouTube et de démontage
- Coût de réparation — données de coûts de réparation et de menus de service
- Marché de l’occasion — prix de l’occasion / du reconditionné sur le marché secondaire
- Web de réparation — blogues d’ateliers et documents de support
- Source ouverte — tickets GitHub à source ouverte
Catégories de composants
- Carte de hachage (ASIC + soudure)
- Domaine d’alimentation (LDO / condensateurs de filtrage / boost / VRM)
- Carte de contrôle
- Ventilateur / refroidissement
- Bloc d’alimentation (PSU)
- Autre (câblage, connecteurs, capteurs, micrologiciel, interface thermique, ESD/expédition)
Lorsqu’une pièce d’alimentation se trouve sur la carte de hachage (LDO, condensateurs de filtrage, boost, adaptateurs de niveau), il s’agit d’une réparation de carte, non d’un remplacement de PSU. Le bloc d’alimentation mural autonome est une catégorie distincte.
Niveaux de solidité des données
- Niveau A Strong — the failure pattern is corroborated across multiple independent public sources and research lenses, with repair-cost and at least directional price data.
- Niveau B Moderate — solid failure data, but thinner, conflicting or single-lens supporting evidence on price or secondary detail.
- Niveau C Limited — emerging or sparse public data. Flagged honestly and not padded; treat as indicative only.

| Other (cabling, connectors, sensors, firmware, thermal interface) | PIC U3 (PIC16F1704) 'Fail to read PIC' (usually actually a cable/connector fault) (PIC) | occasionally reported | 2 REDDIT · RWEB |
| Other (cabling, connectors, sensors, firmware, thermal interface) | ESD handling damage (7nm, <100V) / shipping damage (ESD/shipping) | occasionally to frequently reported | 2 RWEB · YT |
Symptômes notables : “Chain[x] only find N asic, will power off hash board”; “ASIC75”; “ASICNG:(X)”; “PatternNG”.
Signal de coût de réparation : Board-level hashboard repair is widely listed around US$100–$175 by third-party shops. D-Central's own tiered pricing runs L1 $95 / L2 $145 / L3 $195 CAD; the repair estimator puts an S19 hashboard at roughly $200–$500 CAD, with a replacement board around $291 CAD. Burn-damaged boards are generally not repairable.
Signal du marché de l’occasion : Public marketplace listings clustered around US$300–$900 (range ~US$166–$900; asicprices.com, 2026-06) — roughly CAD $232–$1,256 as an FX-only estimate. A late-2023 reference near US$3,225 shows how steeply the model has depreciated.
Antminer S19 Pro BM1398 Niveau B · Modéré
Spéc. vérifiée : 114 chips / 38 domains / 3 chips per domain / 0.32 V core / 12.6→20 V boost / PIC (U6) / EEPROM (U10)
Agrégé à partir de 5 familles de défaillances de composants signalées par la communauté sur REDDIT, YT, RWEB, RCOST. Solidité des données : MODERATE.
| Composant | Mode de défaillance (signalé) | Fréquence | Sources |
|---|---|---|---|
| Hashboard (ASIC + solder) | ASIC at chain tail + cold solder joint -> partial chip count (pattern frequent; one BitcoinTalk thread anecdote is single) | frequently reported | 3 REDDIT · YT · RWEB |
| Power domain (LDO / caps / boost / VRM) | Per-domain filter caps / LDO -> 0 chips, domain voltage drop | frequently reported | 3 REDDIT · RWEB · YT |
| Power domain (LDO / caps / boost / VRM) | Boost circuit / domain voltage -> 'get power type version failed' | occasionally reported | 1 YT |
| Hashboard (ASIC + solder) | New-unit early-life chip 'Abnormal' (factory/early-life defects) (Bitmain community) | occasionally reported | 1 RCOST |
| Other (cabling, connectors, sensors, firmware, thermal interface) | Cascading bricking after SD-reflash (healthy boards entered 'abnormal state') (BitcoinTalk 5348903; firmware/cascade) | single anecdotal report | 1 REDDIT |
Symptômes notables : “Chain 1 only find 109 asic” (72 TH vs 110); “signal interrupted at chip 109, chip 110 is bad”; “0 ASIC chip”.
Signal de coût de réparation : Served under the S19-family board-level menus (third-party board repair parallels the ~US$100–$175 S19 tier; D-Central tiered as S19). Confirm scope after diagnosis.
Signal du marché de l’occasion : Thin and conflicting — do not pin a single number. A late-2023 reference near US$3,734; 2026 used units quoted ~US$2,200–$2,600 with warranty (≈CAD $3,015–$3,560); per-TH math (~US$10–12/TH) implies ~US$1,100–$1,320 for a 110 TH unit (≈CAD $1,500–$1,810). Low confidence.
Antminer S19j Pro / S19j Pro+ BM1362 (S19j Pro+ = BM1362BD) Niveau A · Fort
Spéc. vérifiée : 126 chips / 42 domains / 3 chips per domain / 0.30 V core
Agrégé à partir de 6 familles de défaillances de composants signalées par la communauté sur REDDIT, YT, RWEB. Solidité des données : STRONG.
| Composant | Mode de défaillance (signalé) | Fréquence | Sources |
|---|---|---|---|
| Hashboard (ASIC + solder) | Incomplete chip detection 'Chain[0]: find 0 asic' ('most frequently encountered' per Zeus) (chip corrected to BM1362 vs bible-facts.md summary (VERIFY V1)) | frequently reported | 3 REDDIT · YT · RWEB |
| Hashboard (ASIC + solder) | Poor chip soldering / un-tinned pads (pins look tinned but no contact) | frequently reported | 2 REDDIT · RWEB |
| Power domain (LDO / caps / boost / VRM) | 0.8V/1.2V filter caps short + LDO -> 'ASICNG:(0)', domain voltage loss ('most conditions') (single lens but flagged 'most') | frequently reported | 1 RWEB |
| Power domain (LDO / caps / boost / VRM) | Boost 15V->20V (C915) | occasionally reported | 1 RWEB |
| PSU | PSU (APW12) won't power on / dead fans -> replace PSU first (standalone wall PSU bucket) | frequently reported | 1 YT |
| Other (cabling, connectors, sensors, firmware, thermal interface) | Temp sensors U5/U7/U8/U9 (sensors) | occasionally reported | 1 RWEB |
Symptômes notables : “find 0 asic”; “ASIC113” (114 at 115200 baud, 113 at 12M); “PIC sensor NG”.
Signal de coût de réparation : Board-level repair listed around US$150–$200 (2–3 day turnaround, burn excluded) by third-party shops; D-Central tiered CAD as S19. A skilled-labour job (BGA rework station, 350–380°C, double-tested) underpins the band.
Signal du marché de l’occasion : S19j Pro used ~US$297–$980 (asicprices.com; clear data-error rows at $5k–$6.4k excluded) ≈ CAD $414–$1,367. Refurb-with-warranty (96 TH) around US$1,500 (≈CAD $2,092). S19j Pro+ trades mostly bundled-with-hosting — no clean standalone figure. Negative day-1 profit at low power cost explains the depressed prices.
Note d’exactitude : Chip is BM1362 (the BM1398 grouping in quick-reference summaries is imprecise; the detailed hardware reference confirms BM1362). Repair guides had it right.
Antminer S19 XP BM1366 Niveau B · Modéré
Spéc. vérifiée : ~100 GH/s per chip, 21.5 J/TH; 110 chips; domain split documented as “varies”
Agrégé à partir de 4 familles de défaillances de composants signalées par la communauté sur YT, RWEB. Solidité des données : MODERATE.

Symptômes notables : Hot-spot chips; chain reports below nameplate.
Signal de coût de réparation : No dedicated S21 Pro menu price isolated — serviced under the S21 class (~US$300 third-party) plus BM1370 chip swap.
Signal du marché de l’occasion : Used around US$1,199 (234–245 TH) ≈ CAD $1,643–$1,672; some eBay refurb and aggregate figures range much higher (treat with caution); new clusters ~US$1,358–$2,500.
Note d’exactitude : A repair-vendor “65 ch / 13 dom / 5-per” layout is not treated as canonical (board layout documented as “varies”). Power-domain failure modes are inferred from the S21 generation, flagged as emerging.
Antminer S21 XP BM1370 Niveau B · Modéré
Spéc. vérifiée : 91 chips / 13 domains / 7 chips per domain / ~1.04 V / MP2019 boost (U146/U202) / 12 level shifters (U1–U12)

| Composant | Mode de défaillance (signalé) | Fréquence | Sources |
|---|---|---|---|
| Power domain (LDO / caps / boost / VRM) | TPS546 (TPS546D24S) VCORE regulator - narrow VIN 4.8-5.3V; sag <4.5V trips 'Power Fault Detected'; can latch needing physical disconnect; 105C VRM thermal shutdown. Worst on Gamma (VRM; VERIFY VIN window V8 / part V7) | frequently reported | 5 REDDIT · YT · RCOST · RWEB · OSS |
| Hashboard (ASIC + solder) | BM1370 '0 GH/s pulling ~5W' - soft/API restart does NOT recover; only full cold power cycle clears it. GitHub #588 = '>=3 of reporter units' (single multi-device anecdote, NOT a rate) | frequently reported (Gamma-specific) | 5 REDDIT · YT · RCOST · RWEB · OSS |

Symptômes notables : AC LED green + 0 V out; 8–11 V instead of 12 V (sync MOSFET); output ripple >0.1 V (bulk cap).
Signal de coût de réparation : No North-American shop price isolated; a spare-parts kit repairs roughly 3–5 PSUs per vendor estimate (wider “30–50 PSUs” is a marketing claim).
Signal du marché de l’occasion : Replacement units are sold but prices are not cleanly isolated — do not invent.
Note d’exactitude : A re-torque-fixes-“~95% of no-output cases” figure is a vendor claim, quoted with attribution.
Schémas de défaillance transversaux
- Daisy-chain death — one dead or cold-solder chip disables the whole hashboard (downstream chips vanish). Seen across the S19, S19 Pro, S19j Pro, S21, T21, S17, L7 and Avalon families, and behind Whatsminer Error 542. The single most-reported ASIC failure family, explained by the series-wired hashboard architecture.
- Thermal-shock solder cracking on power-cycle — hot-to-cold cycling cracks marginal joints (“it was fine, then I rebooted it and a board died”). The 2025 headline finding on the S21/T21 generation.
- Power-domain failure — LDO drift plus 0.8 V/1.8 V filter-cap shorts and boost faults are the leading board-level “0 chips” cause across the S19, S19 XP, L7 and S21 families.
- Connectivity-first “not detected” — ribbon / signal cables, connectors, loose copper-bar bolts (Whatsminer) and controller-connector corrosion (Avalon) are the cheapest and most common not-detected causes.
- PSU is the dominant non-chip family — APW3++ cold-start and cap degradation; Whatsminer power-protection errors and copper-bolt torque; Bitaxe / NerdQaxe VRM and input-voltage sag.
- BM1370 voltage sensitivity — a narrow input window and a 0-GH/s-needs-cold-boot behaviour are documented in the Bitaxe Gamma ecosystem; extending this to the full S21 Pro/XP line is inference, flagged as such.
- VR/VRM is the open-source thermal bottleneck, not the ASIC — the regulator (CSD95472Q5MC on NerdQaxe, TPS546 on Bitaxe) overheats first, and the default telemetry often hides its temperature.
- Thermal-interface degradation — paste “measured in months”: S17 heatsink delamination (signature), Avalon dry-out, Bitaxe / NerdQaxe thermal-interface gaps.
- The S17/T17 line is the most-cited poor-reliability generation — a mix of community opinion and a third-party “30% failure” estimate (attributed, never presented as a measured rate).
- Newest flagships are sparse — S21 Pro/XP/+, Avalon A14/A15, Whatsminer M53/M56S are mostly in-warranty or commercial, so community data is thin. Stated honestly, not padded.
