Netcup.eu root servers. Do they go beyond base frequency?
Hi. I've got a root server with 2 cores/8GB RAM. They advertise in their site they use AMD Epyc 7702 processors. In the specs they have 2.0 Ghz of base frequency reaching up to 3.35 Ghz.
In my computer when I run 'lscpu' I get Min and Max Mhz, but then I get into the server and do the same and I don't get any reference to Max frequency. Just base ~1.996 Mhz per core.
Also I have noticed that output from lscpu throws that I get 1 thread per core. Original procesor have 2 threads per core.
I am missing something?

Frequency got capped and you can't do anything about it.
I don't know now where is the line of scam, but certainly not far away.
I don't see the point of advertising cutting edge processors and doing this.
Yes, it's cheap, but I would rather not to be cheated.
KVM will show you stock base clock, not current one. Thats why it's showing 2Ghz instead of any higher value.
But it's possible to know if it works beyond that?
Not possible. You can only see the real frequencies on the host server. Like @TeYroX said, KVM only shows the base clock.
Maybe this thread can give you some highlights:

Thank you for the resource. I got to understand it with the help of google translator.
It is my understanding that it won't pass beyond the base frequency then.
I am somehow upset. It is cheap and the service so long has been good, but I feel I have been played with their marketing materials. The offering is not clearly stated.
Time to sue then.
In Netcup dedicated cores = dedicated threads.
They just guarantee that they wont throttle cores if you will put heavy load on it. Your performance still can be different because of neighbors (cache penalty, load on second thread).
That's true for pretty much every other provider with "dedicated vCPU". There are some exceptions for ex. Oracle where they are using OCPU term instead of vCPU and that means physical core (so 2 threads = 1 OCPU in CPUs with HT/SMT).
Contabo, a direct competitor, offers Hyperthreading in their cores, which effectively translates (and they state it) into 2vCores per every physical core. Also their base frequency is much higher (2.8 Ghz) -> https://contabo.com/en/vds/
I think they are less misleading.
No sure about direct comparison, though.
As I understand it, the hypervisor decides whether to increase the frequency, but this is not visible to the guest.
In any case, the service is very stable and with an excellent performance for the price.
When I was hosting with them, my frequency got capped.
I agree, but the point is that if you advertise something X, you expect something X, not something X-Y.
Their service and offering is good enough, they shouldn't use these dirty tricks.
I have written to support to confirm this is true. I will share here the answer.
just avoid netcup if have CPU problem. many Better provider if no need alot data transfer.
I don't have them -yet, but it's hard to beat their offering. For an IoT backend data transfer and availability of cores are important. What other do you have in mind?
I switched off Netcup after they've sold me advertised 200gb as raid1 which turned out to be 100gb usable in the end. Since then i do not suggest them to anyone anymore.
The amount of CPU steal though at contraboe
What's contraboe? Don't understand.

You don't any better, even if the CPU resource looks higher.
I've got my answer, and I will share it here as I promised:
"We cannot guarantee the boost clock of the CPU due to limitations. We can therefore only guarantee a clock speed which is between the Min. & Max. speed of the CPU."
