the same 0x1387 chip id as the s9 voltage is regulated per voltage domain never per chip multiple chips share one dc dc converter on a domain so you cannot tune a single chip s voltage two voltage numbers both correct the per domain rail voltage is the regulator output feeding a domain e g the bm1370 s21 xp rail is 1 04 v the per chip core voltage is the lower vcore the silicon actually runs at stepped down by on board ldos e g the bm1370 core is 0 40 v a spec card quoting 0 40 v and a board reading 1 04 v on the rail are not in conflict they measure different points the s21 generation has no pic controller it was removed with the bm1368 a missing pic on an s21 is normal not a fault the bitaxe gamma is bm1370 the supra bm1368 the ultra bm1366 there is no bm1371 s19 76 chips board s19 pro 114 chips board both bm1398 on a 38 domain board differing only in chips per domain where a value can t be verified from public sources microbt publishes no chip part numbers and avalon s tuning tables are encrypted on device this database says so rather than guessing frequently asked questions what chip is in the bitaxe gamma the bitaxe gamma uses a single bitmain bm1370 the same 5 nm chip generation as the antminer s21 pro xp the supra uses the bm1368 and the ultra the bm1366 there is no bm1371 multi chip boards such as the gamma duo and gt simply pair two bm1370s credit skot9000 and the open source miners united community how many chips are on an antminer s19 vs s19 pro hashboard an s19 hashboard carries 76 chips 2 per voltage domain an s19 pro hashboard carries 114 chips 3 per domain both use the bm1398 on a 38 domain board they differ only in chips per domain confusing the two is the single most common s19 spec error online is voltage set per chip or per domain on a mining asic voltage is regulated per voltage domain never per individual chip several chips share one dc dc converter on a domain and are wired in series so a single shorted chip drops the whole domain firmware tunes frequency per chip but voltage per domain why does the bm1370 bitaxe gamma s21 xp show 0 40 v some places and 1 04 v others because they are two different both correct measurement points the per domain rail is the regulator output that feeds a whole voltage domain about 1 04 v on a bm1370 s21 xp board the per chip core vcore is the lower voltage the silicon itself runs at after on board ldos step the rail down about 0 40 v for the bm1370 a spec card quoting 0 40 v and a board reading 1 04 v on the rail are not in conflict this database lists both side by side why does my antminer s21 have no pic chip that is normal the pic controller was removed starting with the bm1368 generation so the entire s21 family ships with no pic a board reading no pic on an s21 is expected not a fault only s9 era through s19 era boards carry one can i swap a bm1397 for a bm1396 s17 vs s17 no the s17 t17 generation uses the bm1397 and the s17 t17 the bm1396 they report different getaddress ids and firmware dispatches on that word so they are register similar but not interchangeable bm1393 is a named only s9j refinement that reports the same 0x1387 id as the s9 it is not the
