How to manually control Turbo boost?

post #1 of 6
Thread Starter 
Hi
I have tried many Xeon E5 v3s
They all have turbo boost technology; however, I never see them working at the max turbo speed.
I know that for most E5s, the max turbo speed can only be applied to one core (two threads) while others are running at lower frequencies.
I have an Xeon E5-2683 V3,
The base clock is 2.0
it has a turbo speed up to 3.0Ghz for one core
It has all core max turbo at 2.5Ghz
I tried a few applications that only use single/double threads, but I NEVER see the CPU working at 3.0Ghz
If I disable EIST (Speedstep)
CPU will run at 2.5 Ghz for all cores all the time. No 3.0Ghz neither.
Is there anyway to force one core to work at 3.0G?
(No overclocking for Xeons, btw)

If you want your processor to run at max turbo frequency all the time, I would suggest changing your Power Options (in windows) to "High Performance"

I had this setting selected and my processor would operate at max frequency all the time until I switched it down to "Balanced" where the CPU would turbo down and operate at lower voltages.

I hope this helps. GL

Depending on what OS you are using, in Windows, I know you can set the computer to a "High Performance" setting which causes the CPU to run at the max frequency and voltage specified.

I have tried doing this. High performance mode will make all core running at 2.5Ghz. What I need is to force at least one core to run at 3.0Ghz.

Xeon E5s cannot run at max for all cores.
2683v3 can run at 2.5G for all cores.
I need at least one to run at 3.0G max turbo.

2683v3 can run at 2.5G for all cores if you choose high performance mode.
I need at least one to run at 3.0G max turbo.
