" rel="nofollow - Hello. Hi, I bought a Coffe Lake 8600k with Asrock Fatality k7 z370. I'm not the only one that's happening, but there is a problem with the AVX Offset. When you set an AVX offset, in all games I've tried, the frequency oscillates a lot between the set frequency and the AVX frequency. I understand that games do not use AVX instructions. What's going on? |

" rel="nofollow - Nobody? If I'm not mistaken: If I run OC CPU at 5Ghz and AVX offset at 4.7. Why does the CPU range from 5 to 4.7 in games? :-S If the games do not use AVX, it should be in 5GHz: -S |

| I believe it's been broken since z170 so the chance of them fixing it now is slim I just leave it off since I don't do any avx code |

| From what I've read some games do actually use AVX but it's usually for things like the main menu. Just turn it off if it bothers you. |

| The oddness is you can run a stress test that you know doesn't have avx and it will drop the speed down . Unless i am mistaken but at this point not super interested to go back and test it again |

| Set AVX to auto which is 0 and set your windows power options to performance mode. See if that helps. |

| Same problem. Auto defaults to an Offset of 4. There is no way of setting 0 Offset. Please fix this. |

| This is a problem with ALL mfg boards and Coffee Lake CPUs. It's CPU behavior, no one is exactly sure why. |

I asked support the same question as i always got the 4 avx ratio when set to auto on my Z370 Fatality ITX. You have to set "Multi Core Enhancement" to disabled, then AVX auto is actually 0. If "Multi Core Enhancement" is not visible, you first have to set CPU Ration back to "Auto" to make the option visible.

Hi guys, can confirm this on my MB as well. I have AVX offset = 2 atm and my (OC) CPU freq. oscillates between 4,6-4,4ghz doing nothing in desktop. If I set auto then offset = 0 but does not turn off AVX instructions. If it affects all MBs and Coffee Lake CPUs as said above I'm afraid its not goin to be fixed. ------------- i5-8600K/Asrock Fatal1ty Z370 KG/16GB HyperX 3200MHz |
