Engineered for \u003cstrong\u003elow power consumption, stable hash rate output and outstanding heat-dissipation behaviour\u003c\/strong\u003e, the BM1373CC is the standard replacement part for S23 Hydro hashboard repair — installed at the failed chip positions reported by the kernel scan or test fixture to restore the board to full hash rate.\u003c\/p\u003e\n\u003ch3\u003eBM1373CC on the Antminer S23 Hydro Hashboard\u003c\/h3\u003e\n\u003cp\u003eS23 Hydro hashboards run a chain of BM1373-series chips wired in series across the per-domain buck converters. A single dead chip breaks the chain and takes out the whole voltage domain in the kernel log; multiple dead chips across different domains usually point to either a thermal event or a power-rail fault rather than chip-level failure. The standard repair flow: \u003cstrong\u003eread the failed chip positions from the kernel log or the BM1373 test fixture, isolate the board, re-tin the suspect pads, hot-air the failed chip off, place a new BM1373CC, re-flow, and re-verify on the test fixture before reinstalling the hashboard in the miner\u003c\/strong\u003e.\u003c\/p\u003e\n\u003ch3\u003eWhen to Replace the BM1373CC\u003c\/h3\u003e\n\u003cp\u003eThree symptom families on an S23 Hydro point at a chip-level fault rather than a power or cooling problem: \u003cstrong\u003e(1) low hash rate\u003c\/strong\u003e against the spec'd target with the miner otherwise stable, \u003cstrong\u003e(2) abnormal hash-rate fluctuation\u003c\/strong\u003e visible in the dashboard's per-board breakdown, and \u003cstrong\u003e(3) offline \/ repeated reboot errors\u003c\/strong\u003e on a single board while the rest of the miner runs clean. In all three, swapping out the failed BM1373CC at the position(s) flagged by the kernel scan typically restores normal operation without any other intervention — and avoids the cost of writing off the entire hashboard.\u003c\/p\u003e\n\u003ch3\u003eReplacement Procedure\u003c\/h3\u003e\n\u003cp\u003ePre-heat the S23 Hydro hashboard to \u003cstrong\u003e130–150 °C\u003c\/strong\u003e with an IR pre-heater so the PCB is brought up evenly before chip removal. Use a hot-air rework station at \u003cstrong\u003e340–360 °C\u003c\/strong\u003e with a small nozzle to lift the failed BM1373CC — the package is small and surrounded by tightly-spaced passives, so protect adjacent components with kapton tape. Clean the pads with flux and solder braid, lay down fresh paste matching the board's process (leaded or lead-free), place the new BM1373CC with vacuum tweezers respecting the orientation mark, then re-flow. Verify on the BM1373-series test fixture before reinstalling the hashboard in the miner and re-pressurising the coolant loop.\u003c\/p\u003e\n\u003ch3\u003eWhy Chip-Level Repair Pays Off on S23 Hydro Boards\u003c\/h3\u003e\n\u003cp\u003eS23-class hashboards are expensive replacement units, and chip-level repair is the right economic call whenever the failure is isolated to one or two positions. A clean BM1373CC swap restores the board to its original hash rate, eliminates the hash-rate attenuation and downtime that come with degraded chips, and keeps the miner generating revenue instead of waiting for a full board replacement to ship. Across a fleet, the cumulative savings on board-replacement cost and downtime are the difference between repairing a site profitably and being forced to scrap usable hardware.\u003c\/p\u003e\n\u003ch4\u003eBM1373CC ASIC Chip Specifications\u003c\/h4\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align: left; padding: 6px 12px;\"\u003eParameter\u003c\/th\u003e\n\u003cth style=\"text-align: left; padding: 6px 12px;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003ePart Number\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eBM1373CC (also referenced as BM1373)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eAlgorithm\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eSHA-256 (Bitcoin, Bitcoin Cash)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eCompatibility\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eAntminer S23 Hydro hashboard\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eKey Properties\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eLow power consumption, stable hash rate, strong heat-dissipation behaviour\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eConfiguration\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eSeries-wired chain across voltage domains\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eCommon Faults Addressed\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eLow hash rate, abnormal hash fluctuation, board offline \/ reboot errors\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eSoldering\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eHot-air re-flow, ~340–360 °C with 130–150 °C hashboard pre-heat\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eTest Fixture\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eBM1373 series test fixture\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eUse Case\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eHashboard chip replacement to restore normal hash rate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eOrigin\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eOriginal Bitmain silicon\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eCondition\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eBrand new\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003e\u003c\/h3\u003e\n\u003ch3\u003eRelated Antminer S23 Hydro \/ Bitmain Hashboard Repair Parts\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/bitmain-bm1370bc-asic-chip-antminer-s21pro-s21xp-s21hydro\"\u003eBM1370BC ASIC Chip – Antminer S21 Pro \/ S21 XP \/ S21+ \/ S21 Hydro\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/antminer-test-fixture-hashboard-asic-universal-tester-s19-s21-s19hyd-t21-all-series\"\u003eUniversal Antminer Hashboard Test Fixture – S19 \/ S21 \/ T21 Series\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/dowsil-8w-blue-thermal-gel-1kg-asic-miner-hashboards\"\u003eDOWSIL TC-3080 8W\/mK Blue Thermal Gel 1kg – Hashboard TIM\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/antminer-s21-hydro-miner-water-cooling-heatsink-plate-upgrade-miner-efficiency\"\u003eAntminer S21 Hydro Water Cooling Heatsink Plate\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eRepairing S23 Hydro hashboards in volume or stocking a workshop ahead of fleet rollout?
