Hi, This issue has been initially described in another thread but I decided to start a separate one. I noticed on my B660-I Gaming, that any negative voltage offset causes noticeable negative performance impact. As the example - results of Cinebench R23 (multithreaded) stock settings: 12700 points 0.05 voltage offset: 12200 points 0.08 voltage offset: 7100 points.
This issue is not present on other Asus B660 motherboards - it's working properly on B660M Plus. It doesn't matter if APE is enabled or not - CPU performance is affected.
My CPU is i5 12500.
It would be good, if someone from Asus tech team compares the behavior of those two motherbaords and make a fix for B660-I as currently undervolting on this motherboard doesn't work at all.
Hi, I've just tested and results in Cinebench R23 are as follows:
CEP disabled, APE Enabled, 0.05V Undervolting: 5900 points
CEP disabled, APE Disabled, 0.05V Undervolting: 11900 points
CEP disabled, APE Disabled, 0.07V Undervolting: 8200 points
I've searched through internet and people are generally having issue with undervolting of non-K CPUs for Intel 12th gen. What I also found is that only MSI found a way to undervolt through option called CPU Lite Load Control, but we don't have it on Asus motherbords.
