Title: Help with btcrecover Post by: opies32765 on May 26, 2017, 12:32:00 PM Hi everyone
I need some help with btcrecover and cannot find a way to contact the developer directly(gurnec). I have set up the program and its working. I have a second GPU that i would like to add to my computer. In the GPU acceleration info for the program there is mention of multiple GPU's. I went ahead and installed a second one but btcrecover is asking me to pick one it says --gpus names....is it possible to add multiple GPU's ? I have run the test and it sees both of them. I cannot figure out what the setting would be ? I have tried naming them but cannot figure it out. I have a GeForce GTX 1080 Ti and a GeForce GTX 1080 my info is below cd C:\temp\btcrecover-master C:\python27\python btcrecover.py --wallet wallet.dat --enable-gpu --global-ws 262144 --local-ws 1024 --tokenlist tokens.txt --no-dupchecks --no-eta --max-tokens 10 --typos 1 --typos-case --autosave savefile thanks in advance..... Title: Re: Help with btcrecover Post by: btchris on May 26, 2017, 08:19:07 PM By default, btcrecover only uses multiple GPUs at the same time if they're identical, but you can force it to use different GPUs if you'd like.
First, ask it for a list of your current OpenCL devices like so: Code: > C:\python27\python btcrecover.py --list-gpus It's easiest to specify the GPUs you want to use by the #ID numbers, so for example to use the two 1080s, even though they're different models: Code: > C:\python27\python btcrecover.py --enable-gpu --gpu-names #1,#2 ... Note that you may get better performance if you use a different global-ws for each GPU (with a bigger global-ws for the Ti), something like this: Code: > C:\python27\python btcrecover.py --enable-gpu --gpu-names #1,#2 --global-ws 262144,196608 --local-ws 1024 ... Good luck! Title: Re: Help with btcrecover Post by: uartasic on June 28, 2017, 10:57:38 AM hey chaps,
i too have been using the brilliant btcrecover software. i have tested on a known password and it works (after 2 solid days) using several omitted characters. for example i had the test password: Apasswordtotest i removed the known end characters and placed the wildcards like this: Apasswordto%P%P%P%P this solved the password. this was just a test. however in my current case i has something like: Apasswordtotest????????etc where the ? is the unknown password characters and unknown length. the password is up to 40 characters long and i know around 25-30 of those characters. any help will appreciated. this one password holds the key for all my crypto wallets. some parts of this password are reordered and reused. the current one i am trying is one of my BTC wallets. sorry about the hijack opies, i am in a bind.

Hi do i need another version of openCL to read my cpu only my gpu shows up when i type --list-gpus? any help would be appreciated Title: Re: Help with btcrecover Post by: HCP on February 09, 2018, 05:34:39 AM What is your CPU? Is it an Intel or an AMD CPU? It might not have a compatible built-in iGPU... which would explain why it isn't detected as a "GPU"
