Core clock response to heavy short peak loads | Server 2016 Hyper-V - AMD W7100

System A+B:

  • Supermicro X10DRi-T
  • 2x Intel E5-2660v3
  • Windows Server 2016 (latest Patch) as Hyper-V role using RemoteFX

only A:

  • AMD Firepro W7100

only B:

  • Nvidia Quadro M4000

 

Problem:

The core clock from the AMD W7100 is not responding fast enough to the heavy peak loads. It is nearly never working above 300-350 MHz. At longer loads it will be like 550 MHz. This affects the userexpirience in a bad way. On system B the Nvidia M4000 is doing it right. It jump from 150 MHz to over 700 MHz when i would expect it. The card is also waiting longer to go down with the core clock. So if there is a burst of short peak loads, it will handle it with its full capacity.

Question:

Is there a way to tell the W7100 to hold a higher base clock?

Or better, to alter the load/core clock dependency curve like you can do in the energy options for the CPU in Windows? There you can tell the CPU to go at 100% clock when the load exceeds 10% or what you need.
