200 Million addresses loaded and working with CPU; GPU untested
It eats up 4300MB, 4.3GB of RAM. Binary to Bloom; I am sure if it was loaded via text file, it would eat up a lot more. Also, I doubt this will work with Bitcrack or any VanitySearch forks.

Very impressive stats you found but I highly doubt you will get any higher than this if you test on GPU, this is because of its architecture where it's memory is separated from all the rest of the system RAM.

So you could have a 96GB system (eg. A very very recent MacBook Pro with an external nvidia GPU (does that even exist??) but the GPU will only have only 8 or 16 gigs total which puts a ceiling on the number of addresses. That's kinda sad as these suckers can easily do 500x the search performance of a single CPU socket.
How does the GPU memory play a part?

How does the GPU memory play a part?

If you want to load 1 billion addresses and work on them at the same time (in parallel), there isn't enough device memory to for everything on current GPUs according to my above calculations. So you'd have to break it into parts and place more copy calls which will affect performance.

Every time NVIDIA increases GPU memory this brings two kinds of speed benefits - one is you can process more stuff on the GPU at the same time, and it will be faster (as CUDA cores usually become faster at the same time) and the other is that as a direct consequence, there's less latency delay from excessive CopyHostToDevice calls and vice versa.

Why wouldn't it work? Because those are set to use .txt files instead? What would you recommend using instead of Bitcrack &co?

I remember (long ago) trying to load like 32 million addresses in the original VS or a fork of it, and it would load them but then not run. I think the same was true for Bitcrack. I would say try them and see, maybe something changed.

I have been testing on my own modified versions of VS and KeyHunt.

Yeah, Bitcrack just froze with 10mil addresses loaded...

Is this your version?

Yes, that is an older version of VBC. However, I did not use it when testing address limits.
I have another VS version that will take binary to bloom.
Keyhunt, by albert, will also accept 200M keys, but it is CPU only but random function is great. You can also do sequential.

Read a few posts above, if you don't mind using a closed source tool in offline mode. If you want to use bitcrack, read github for instructions, if you don't know how to build it on your windows system, neither did I. Lol.

You need to do a google search for cudart64_101.dl; find it, download it, add it to the folder where you are trying to launch bitcrack from.

I tried this method. Downloaded the file. copied to a folder. Restarted the PC. It didn't help.

It is necessary to download the necessary file and drop it in the folder with CUDA

But if you have CUDA installed already it should be there by itself, unless you didn't install the right version. And if you drop the file there you'll face another error for something else missing.

Generally when you get errors about DLL files being missing, you need to make sure they are in the same folder as the .exe file.

I don't know what is Windows' equivalent for LD_LIBRARY_PATH, but I'm not sure such a feature even exists (correct me if I'm wrong), hence why when you open "Program Files" you see a long list of DLLs and EXEs in each folder.

Vs tells you where you need the missing file, cudart is in program files\NVIDIA  GPU Computing Toolkit\CUDA\v12.0\bin

The problem is…you were WRONG!
#64 was solved before #120

Soooo do you want to try again and guess the next challenge to be solved?

People like you crack me up. Especially when you’re wrong!

I did not say nothing about #64!
I only talked about #120, that it will be opened by the developers themselves ...
Do you have problems with your head? Does anyone else think that I was mistaken?
