Exactly that's right!
Yes nice result but you have 6 nice GPUs . With one GPU let's say you would have taken about 15 min it's a good result

Well I did say in my original post, "As always, it depends on the program you are running and how much hardware you have."

That was a 48 bit range; which could take up to 4-5 hours to check every key, so I leaned on the side of caution and ran with 6 GPUs lol...

Thank you for the testing of 14 missing characters, I appreciate it.

That's a 60 bit range C018588C2B6CC47... I'm gonna have to pass on that one lol.


Very nice work! When the release of this new tool?

Hmm yeah I am on it. What gpu are you using?

RTX 3060Ti on home box

GTX 1080 on work box

Win 10 on both box and same error

When you have time could you compile an .exe release please? Would like to test it vs. the original. Thanks.

Done:
https://github.com/Uzlopak/BitCrackOpenCL/releases/tag/v.0.4.0

I also tested the performance:
On my System with a Vega56 I had at the beginning with the old clBitCrack about 58 MKeys/s. Now I get about 83 MKeys/s. Keep in mind: This is just without any specified -b -t -p parameters, which will increase the throughput significally. with -p 5000. I get about 215 MKeys/s. With the old clBitCrack I get with -b 5000 about 190 MKeys/s. If I change only -b to 512 I get about 130 MKeys/s

So the 30 % Improvement are significantly when having low pressure on the GPU. On big load I get "just" 12 % improvement.

I read you can get the bytecode of the on-the-fly compiled openCL part.I will probably implement a solution to store the compiled openCL bytecode in the same folder and load if you run again clBitCrack. Thus should speed up the starting speed... Testing the best parameters should be then not taking always 20 seconds, because OpenCL is building.....

EDIT:
I get with clBitCrack.exe -i addresses.txt --keyspace 1:fffffffffff -b 512 -t 256 -p 256 about 268 MKeys/s

With the old clBitCrack I get in the same case about 210 MKeys/s

So the performance gain is definetely there Wink

"Original" bitcrack works normal.
Suggestion?

Thanks Gun!!!
I bought the software and tested for a week with a capital of 0.04 BTC.... just a word....wonderful !!
My personal recommendation: let GunBot do your job, do not be greedy, and nothing will go wrong  Grin Grin Grin
Great work Gun

If you don't mind to share it,how much you gained in that week starting with 0.04 BTC? I am keeping an eye on the bot and I am thinking about buying it.


Hi Mirko ( I'm from Ita too  Wink ), in 5 days, to be precise, I gained 0.00212563 BTC, or 5% of my invested capital.
I'm on 3 pair.

- BTC/ETH
- BTC/DASH
- BTC/XMR ( this pair only is in Supergun mode )

It's a little profit, I know, but considering the small initial capital it's a great result imo.
Consider also that profit is made without any intervention from me ( obviously excluding the initial configuration and the choice of the pair on which to operate ), and for me this is a great thing....while I'm working in my office, the Gunbot work for me from home....I love it!  Grin Grin

Hope this help in your choice

You're absolutely right, we're still finishing to define the graphics of the site and we are in beta.
Soon we will provide all the information about who runs the site and the operation area.

Thank you for the feedback, you are welcome.
