As you can see the frequencies are 800Mhz, 1520Mhz, 3320Mhz, according to the provider's right, I think not, this is problem of bios setting.
What do you think of this?

It is standard and expected for modern Intel processors to run at variable clock speeds and the profile your CPU is on right now is most probably the default. This is the profile Intel expects to be used out-of-box on such a system and there are many benefits of this that go beyond saving power.
One of the main reasons that modern processors prefer variable clockspeeds like this is that it allows them to better manage power and thermal factors such that when the workload calls for it, they can boost beyond their base clocks for a longer period of time. This of course can be enormously helpful ensuring your CPU has the horsepower to get through tougher workloads when it needs to, and it can do that because running at 1.6GHz or other, lower speeds for longer periods of time when the workload is much lighter means that there is less thermal buildup in the heatsinks and chassis air that would otherwise restrict boosting to higher clocks. It also helps the CPU remain inside its power envelope (which on Xeons cannot be changed, so even on a maximum performance setup, the power envelope remains what it is) while achieving those higher boost clocks for longer than it can when it sits at its base clock the entire time.
You could have your provider adjust the CPU profile but before changing any settings like this, you should check whether the current settings are actually resulting in below-expected performance bottlenecks, not below-expected clocks, as the two are not synonymous.

This is actually controlled by the cpuspeed service within Linux. If you stop it, they will all run at their non-turbo speed all the time. It is a waste of energy and your performance will not improve in any noticeable way.

Actually the above is not completely true. It depends on the type of application you're running. Some application do benefit from having the full clockspeed available. The majority of hosting applications will see little to no benefit though.
The reason for the clockspeed throttling down is that C and P states are still enabled. (pretty much a default for most servers unless specifically requested).
Both can be controlled by the OS if you're running Linux. Granted that the BIOS settings allow the OS to overwrite the C-state settings.

Thanks to both for the answers.
So what do you suggest to do? I leave the variable clock that if I understand to increase the requirements? or fixed frequency?

What are you using the server for? If its just hosting or site related I would leave it, let the server determine if it needs more processing power.
And typically the way it should work is 1 CPU core will stay at standard rate and others will scale down until they are utilized which I am seeing on yours as well based on the copy and paste you provided. I wouldn't worry about it at all, its work and functioning as it should.

Yes, this server is only used for hosting. ok, leave server with these settings.
Thank you
