# 295/1100 works fine in windows
# 300/1200 crash blender

# 285/800 crash AMWF
# 280/600 crash AMWF
# 266/0 works fine AMWF, so good interval between 0-600 memory and unknown CPU
# 285/500 crash Blonde Angel
# 266/250 works fine Blonde Angel, good ram in 250-500
# 266/400 works, small file, +1. Good Mem near 400, try to raise GPU
# 295/400 error, I'm so horny. Failed, try to reduce GPU significantly and memory a bit
# 280/350 error, I'm so horny. Failed, try to ensure that 266/400 works for this problem file
# 266/400 ok, I'm so horny. Seems like 266 for cpu is max, try to increase memory
# 266/500 ok, large model. Try to speedup memory again
# 266/600 crash, so good values below 266/600, ensure that 266/500 stable
# 266/500 ok, a lot of tests, try to raise clock a little, 280/500 already problems
# 272/500 ok, continue test. 285/500 and 266/600 are known crash
