Hello . i have two xeons e5-2660v4 and Asus Z10PE-D* ws motherboard. When i use V-ray or Cinebench all the cores full load and works on 2.5 mhz and when i use Coronarender all the cores full load but work only on 2.1 mhz ! I think it because Coronarender use avx and V-ray dont? Is there any possibility to make all the cores work on 2.5 mhz in Coronarender?? May be i should turn on or off in BIOS to makes it works??????????????????????????!!!!!!!!!!
These two values will be reached whenever the task needs it, your processor will behave has the app requires it. As you mentioned, it's possible that one of the apps requires all the resources, but the other won't.
Unfortunately the above information has not helped me, I did not understand why the AVX frequency on my e5 2660 is lower than not AVX frequency .I know that for a single-processor Broadwell-e systems there is AVX Instruction Core Ratio Offset in the bios ....may be on motherboard AVX Instruction Core Ratio Offset is Negative in defaults ?? I have another system with two xeons e5-2683v3 and its have same AVX/NON AVX frequency in render!!!!The question is why in my e5-2660v4 AVX and NON AVX requencys are diffrent ????? Thank you very much for your answers!
I apologize if the information above did not help you.
