Did you change CCAP value to match your GPU CCAP?

i didn't change any gpu value, except change setting on afterburner  to undervolt my gpu.

You must change CCAP to match your GPU or otherwise will not working properly.
You can find CCAP value for your GPU in
here: https://github.com/oladas/ccminer/wiki/Compatibility

wait up, take my medicine for headache first...  
any other easier way to understand?
what command do i have to write for 8xrtx3070ti, so this job can be done.  

btw what is the use of --gpux GPU gridsize: g0x,g0y,g1x,g1y,... : Specify GPU(s) kernel gridsize, default is 8*(Device MP count),128
and how can i use it?

I don't work in Windows so I'm not sure how to do it.
Your CCAP value is "86". the default value "75" will not working.

I done a lot of test for gridsize and the result is that the default one that generate by Keyhunt (when you remove --gpux arrangement) is the best one.
So keep it empty and relax

In Windows its a pain.
But in Linux its just few command line(no programming)

1- sudo apt install build-essential git libgmp-dev python3-pip nano  -y
2- git clone https://github.com/kanhavishva/KeyHunt-Cuda
3- cd KeyHunt-Cuda/KeyHunt-Cuda/
4- nano Makefile (go to line "CUDA       = /usr/local/cuda-11.0" and change it to your cuda version for example "CUDA       = /usr/local/cuda-11.2"
5- make gpu=1 CCAP=21 all

And you ready to go ./KeyHunt....

I really know its look like too difficult but you should do it and take your time, week month its OK.
You can use https://vast.ai/console/ to rent cheap one for few hours and start to learn more about Linux and KeyHunt-Cuda (choose docker image "nvidia/cuda:11.2.0-devel-ubuntu18.04")

Soon i will install ubuntu (or debian) in another old laptop.
Is not possible to run the commands on a linux online website for free?

There ain't no such thing as a free lunch.
If you know anyone provide it for free then please tell me

That kind of good for someone who want to test the Linux system.
But it have there limitations so its not good for any kind of heavy work like keyhunt.

What about renting a cloud server?

https://servdiscount.com/en/vps/rent-linux-vps.html

Here a basic virtual machine costs only 5$/month.  
Is it enough to make keyhunt running there?

I already test all these services  
If you want cheap&faster VM/VPS go with UpCloud
And if you want cheap&faster Dedicated server then go with wholesaleinternet

You need to know that most services not allow to mining and similar behavior like keyhunt, they will block you account immediately over night.

both UpCloud & wholesaleinternet I use it for keyhunt without any problem

Has been difficult to configure upcloud or wholesaleinternet to install and run keyhunt?
Is it like i do it on my linux laptop or is it something more difficult?
(i used for a while an ubuntu laptop some years ago even if i don't remember too much)

Don't you fear that the server admin can read the privkey if you find it?

The install done by host provider. you will get access via SSH terminal. There are no desktop or graphic interface, you have just terminal (text interface)
So you need to be OK with using terminal for all things.(just few command to learn and you ready to go)
*They are some host that provide Windows desktop but its so expensive compare to Linux.

You will be the only admin in that host, the connection and access will require your SSH-RSA.

SSH-RSA is secret and public keys. The provider will ask you to give them your public key to encrypt your host and you will be the only one can access it via your secret key.

It's very interesting, but i have a doubt:

The cheapest solution on https://www.wholesaleinternet.net/dedicated/ costs 9$/month: Intel Core2Duo 1,6Ghz 1 processor 2 cores 2 threads RAM 4 Gb DDR2 250GB SATA

My laptop has an Intel i7 4500U 1,8-3,0 Ghz 2 cores 4 threads RAM 8 Gb DDR3 250GB SSD.

My laptop seems more powerful or am I missing something?

My laptop is 65W so with italian high cost (0,00032 W/h) i could pay 15$/month (9$/month seems better).

You should go with Xeon processor if you want to have chance. less than that is absolute zero(bitcoin range is tooooooooooo...etc big)

You miss about cooling because you laptop will run 100% all time which will cost you much then that.
And also don't miss the noisiness

Noisiness for sure during the night .
It does not seem to overheat much with keyhunt, not using the gpu in my opinion it does not consume more than 2 times the 15W declared by Intel for the middle cpu usage plus something for the rest of the hardware maybe it does not reach 30-40W (65W is the maximum of the transformer).

How many privkeys can you examine monthly with your rented Xeon? How many keys/s does it reach?

Prices for 36 cores/72 threads is 100$/month.  
How many privkeys do you think can i examine in one month with a Dual Xeon E5-2696v3 128 GB 2x2 TB SSD?

I was had 9 servers (Dual Xeon E5-2696v3) each one of them have speed for rmd160  ~56 Mkeys/s (56918732 keys/s) and for bsgs ~2 Ekeys/s (2476793317881701990 keys/s)

Why 9 Xeon cpu if a single GPU 3070 can reach 1337 MKey/s?

Yeah I learn my lesson so all my search now is on GPU.
But you keep talk about going with CPU so I give the advice to go with top one to reduce your lesson time and cost to half  

In vast.ai the RTX 3070 is 1200 MKey for 0.069h, For month 0.069x24x30=49.68$ half of one dual Xeon server price.

The public key usually only used as SSH authentication though, rather than encrypt the host itself.

I agree with that because the data must be available any time uncle sam request it
