Packages carry the marking \u003cstrong\u003eA3197MC\u003c\/strong\u003e, while the machines’ own firmware identifies the core as \u003ccode\u003eA3197S\u003c\/code\u003e — two names for the same silicon series, which is worth knowing before concluding a part is “wrong” for your board.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ccolgroup\u003e\n\u003ccol\u003e\n\u003ccol\u003e\n\u003c\/colgroup\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eCanaan Avalon Q\u003c\/td\u003e\n\u003ctd\u003eInternal board, 160 chips per unit — single-chip replacement is included in our \u003ca href=\"\/products\/avalon-q-repair-service\"\u003eAvalon Q repair service\u003c\/a\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCanaan Avalon A15 series\u003c\/td\u003e\n\u003ctd\u003eSame A3197 chip family across the A15-generation hashboards; confirm your exact board revision with us before ordering in volume\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eQuality and Testing\u003c\/h2\u003e\n\u003cp\u003eEvery chip is validated on the bench before it ships. The A3197 carries its temperature and voltage sensing on the die itself — which means a marginal chip cannot hide: it shows up in the machine’s own per-chip telemetry the moment the board runs. We hold parts to that same standard before they leave the lab, so the array you see after installation reads flat.\u003c\/p\u003e\n\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\n\u003cp\u003eThis is a BGA component. Replacement requires hot-air or infrared rework, correct reballing, and post-install verification against the machine’s per-chip readout — it is not a socketed or hand-solderable part. A failed A3197 also cannot be bypassed or masked in firmware: because its PVT sensor is on the die, one corrupted chip will keep triggering the board’s protection logic until it is physically replaced. If you would rather not do the rework yourself, one chip replacement is already included in the flat price of our \u003ca href=\"\/products\/avalon-q-repair-service\"\u003eAvalon Q repair service\u003c\/a\u003e.\u003c\/p\u003e\n\u003cp\u003eOrdering more than a handful, or matching a chip to an unusual board revision? \u003ca href=\"\/pages\/contact\"\u003eContact the lab\u003c\/a\u003e with your board photos and firmware readout — we will confirm fit before you commit.\u003c\/p\u003e","brand":"Canaan","offers":[{"title":"Default Title","offer_id":54407184285969,"sku":"CHIP-A3197","price":30.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/antminer-repair.com\/products\/a3197-asic-chip","provider":"Antminer Repair","version":"1.0","type":"link"}
