Small scripts to control Nvidia GPUs frequency offsets
Second edition now uses python. Requirements: Driver 555+ Python 3.12 nvidia-smi <=565 (only for voltage reading)
Basic offset controller with advanced settings.
Settings explanation:
nvidia_smi_lgc_min & nvidia_smi_lgc_max -set range GPU frequencies should work (RTX 30xx desktop & mobile (Ampere arch) & up only)
frequency_min & frequency_max - set frequencies range for offset calculations
freq_offset_min & freq_offset_max - set main offsets to calculate offsets between frequency_min & frequency_max
temperature_min & temperature_max - set temperatures range for additional offset calculations
plimit_min & plimit_max - set GPU power consumpion range for additional offset calculations
low_freq_min, low_freq_max, high_freq_min, high_freq_max - additinal offset, which applied with positive coefficient at low frequencies and negative coefficient at high frequencies, because of transistors characteristics. Controlled by variable drain_offset_control
drain_offset_lmin, drain_offset_lmax, drain_offset_hmin, drain_offset_hmax - offset, which take into account tranfer characteristics of transistors with regions of positive and negative temperature coefficient. Controlled by variable drain_offset_control
power_offset_max, power_offset_min - additional offset, which further downvolt GPU core, because GPU core can work with lower voltage when not fully loaded. Controlled by variable power_offset_control
critical_range_offset - additional setting to prevent GPU instabilities because of voltage fluctuations in a predefined temperature range by disabling drain offset calculations in that region
