3070 pearlhash(int8)のメモ

0
Posted at

core offset +150 (via nvml)

sudo nvidia-smi -pl 120
sudo nvidia-smi -lgc 1350
sudo nvidia-smi -lmc 5000

ozminer 1.8.4 で 750 GH/W(0.75 TH/S)

3070 63.08 TH/s 2/0/0 750.44 GH/W 60°C 69% 84.1 W 1350 MHz 5001 MHz

gpu-unlock は使用しているが, 現在の pearlhash は int8 なので効果はない.

おまけ

nvml で offset 指定.

import sys
import pynvml as nv

core_offset = int(sys.argv[1])
memory_offset = int(sys.argv[2])

nv.nvmlInit()
try:
   gpu = nv.nvmlDeviceGetHandleByIndex(0)
   print("GPU:", nv.nvmlDeviceGetName(gpu))
   print("Core range:", nv.nvmlDeviceGetGpcClkMinMaxVfOffset(gpu))
   print("Memory range:", nv.nvmlDeviceGetMemClkMinMaxVfOffset(gpu))

   nv.nvmlDeviceSetGpcClkVfOffset(gpu, core_offset)
   nv.nvmlDeviceSetMemClkVfOffset(gpu, memory_offset)

   print("Core offset:", nv.nvmlDeviceGetGpcClkVfOffset(gpu))
   print("Memory offset:", nv.nvmlDeviceGetMemClkVfOffset(gpu))
finally:
   nv.nvmlShutdown()
