https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D221071 --- Comment #5 from Nils Beyer <nbe@renzel.net> --- (In reply to Andriy Gapon from comment #4) okay, so the value that "superiotool -de" spits out already is the current temperature in =C2=B0C. Got it. What about VCORE voltage. This is the logic: ---------------------------------------------------------------------------- #define RFACT_NONE 10000 + { .desc =3D "VCore", .type =3D ENVSYS_SVOLTS_DC, .bank =3D 4, .reg =3D 0x80, .refresh =3D lm_refresh_volt, .rfact =3D RFACT_NONE / 2 }, + data =3D (*sc->lm_readreg)(sc, sc->lm_sensors[n].reg); if (data =3D=3D 0xff) { sc->sensors[n].state =3D ENVSYS_SINVALID; } else { sc->sensors[n].value_cur =3D (data << 4); if (sc->sensors[n].rfact) { sc->sensors[n].value_cur *=3D sc->sensors[n].rfact; sc->sensors[n].value_cur /=3D 10; } else { sc->sensors[n].value_cur *=3D sc->lm_sensors[n].rfa= ct; sc->sensors[n].value_cur /=3D 10; sc->sensors[n].rfact =3D sc->lm_sensors[n].rfact; } sc->sensors[n].state =3D ENVSYS_SVALID; } ---------------------------------------------------------------------------- bank 4, register 0x80 reads: 0x42 -> 66 1) it's not 0xff, so go on 2) shift left by 4 -> 1056 (I'll keep decimal for now) 3) "rfact" is set (I think), so multiply that with "rfact" (5000) -> 5280000 4) divide that with 10 -> 528000 So my CPU is running with 528000V or (if millivolts: 528V). Lovely, hard to cool it, though... --=20 You are receiving this mail because: You are the assignee for the bug.=
