Hi Denis, Testing results for ROG STRIX X870E-E GAMING WIFI. System Info: Board: ROG STRIX X870E-E GAMING WIFI (DMI vendor: ASUSTeK COMPUTER INC.) Kernel: 6.19.8-1-cachyos (CachyOS, Arch-based) Chip: NCT6796D-S/NCT6799D-R Key Finding: This board needs to go in asus_msi_boards[], NOT asus_wmi_boards[]. The ACPI WMI device has UID AsusMbSwInterface (not ASUSWMI), so asus_wmi_boards[] do= es not match. BEFORE patch (ISA path): dmesg: Found NCT6796D-S/NCT6799D-R or compatible chip at 0x2e:0x290 No WMI mention in dmesg PWM writes via ISA held intermittently but firmware can override AFTER patch (WMI path via asus_msi_boards[]): dmesg: Using Asus WMBD method of AsusMbSwInterface to access 0xc1 chip WMI read confirmed: ret=3D0 tmp=3D0xc1 PWM writes persist for 22+ seconds Fan RPM responds correctly: 1468 =E2=86=92 1153 RPM when setting PWM to 200 Firmware does NOT override manual control The patch (one line added to asus_msi_boards[] in nct6775-platform.c): "ROG STRIX X670E-I GAMING WIFI", + "ROG STRIX X870E-E GAMING WIFI", "ROG STRIX X870E-H GAMING WIFI7", Full before/after dmesg logs and PWM test results attached if needed. --=20 You may reply to this email to add a comment.
