It sounds like you have never even checked the UEFI/BIOS, or the manual for your board, sorry to say.

Have you installed the new Intel Management Engine software (IME) for you board? There is a new version for use with Broadwell-E processors. Your board is not fully Broadwell-E compatible until you apply the Broadwell-E compatible UEFI update (which you have), and the Intel Management Engine driver ver:11.0.4.1186, from your board's download page.

While we have no idea what version of Windows you are using, the download file seems to be the same for every version of Windows, this is the Windows 10 64bit page:

http://www.asrock.com/mb/Intel/X99%20Extreme43.1/?cat=Download&os=Win1064

In the UEFI/BIOS, the Main screen will show what can be read from your ES processor regarding its base speed and current speed. The official specs for a Xeon E5-2680 v4 are 2.4GHz base speed, and 3.3GHz Turbo speed.

In the OC Tweaker screen, click on CPU Configuration to display many of the options that will interest you.

Click on CPU Ratio, which by default will be set to Auto. Change it to Per Core. That will show you the Turbo configuration built into the processor. That is, the Turbo core speeds when one or more cores are being Turbo boosted.

If your ES Xeon is anything like a production version, you should see 14 core multipliers listed, the first one with a value of 33, with the cores below with lower multipliers, descending by a value of one (usually) as you go down the list, until you reach the base frequency multiplier of 24.

If you don't see that list of descending multiplier values, it's an ES version so anything goes. You may be able to set the multipliers to values from 33 to 24, or all of them to 33, depending upon how unlocked your CPU is. If the highest multiplier you see is 22, that explains the 2.2GHz processor speed, but that is only for one of the 14 cores.

Further down that same page you'll find the Intel Turbo Boost Technology option, which will be Enabled by default. Given your ES Xeon, and its unknown (to me) set of core multipliers, verifying this option is enabled is the only way to know Turbo is Enabled.

The CPU Core Voltage option will be displayed in the FIVR Configuration screen, which is listed on the OC Tweaker screen.

So currently your ES Broadwell-E Xeon runs at 2.2GHz, and goes down to 1.9GHz? What are you using to monitor the core speeds?

I have an Xeon E5 2680 v4 (ES) and don't know how to tell if the turbo is working. It underclocks from 2.2 to 1.9 under load. Works fine and I understand that this is an ES CPU and their are no guarantees.  But is their a BIOS setting for voltage etc... and a way to make sure turbo is enabled?
