Not sure at what rate you're leasing a Tesla A. But isn't it cheaper to buy, for example, a 3060?
Ofc I'm not familiar with shipping and stocking in your country Smiley

I'm overseas ATM so I'm in the process of leasing a custom server from walkerservers.com. They're the only guys who accept crypto and offer GPUs at the same time.

They also only have Teslas, so no GeForce or Quadro for me.  Cry (you gotta request a quote from their sales dept for one, they aren't available in the product listings.)

PPS. do not get a 3060 until someone confirms whether they throttle on these programs, that card in particular throttles itself for ethereum mining, and I have no idea if it classifies private key bruteforcing as ethereum mining, as they both use ECC, and'll throttle on these programs too.

I see, I could free up a windows desktop with a 3080 or 3070 if thats something you're willing to work with?
Would need to request and need a time-window (1 week, 2 weeks?) for it, but could work it out for free.

Offer noted if I need it in the future, but someone else here contacted me first and got me a GPU to work with. Thanks though.

Why waste so much electricity with the brute force attack when you just need to solve a simple mathematical problem?  Grin

This explains nothing. He probably owned the private keys to that wallet already.

EDIT: you should back that claim up with more than a decrypt.co news story.

10xx series cards work with cubitcrack without issue, regardless of drivers.
20xx series cards work with cubitcrack, if you roll back drivers to 452.06 or 456.02 (can't remember which)
30xx series cards do not work with cubitcrack no matter the driver

Got it. Better avoid getting a Pascal or Maxwell then.

The Tesla I'm leasing for Kangaroo will also be used to patch the long standing misaligned address CUDA error, so I need to know if anyone here has experienced this error on a Pascal or Maxwell GPU so I don't lease one of those cards unknowingly and kick myself later, I have a limited budget allocated for this and these things 'ain't cheap.

PS. It was 452.06 you roll back to.

Roll back your graphics driver to 452.06; only way it will work. Or the only way that I and others have got it to work

"Fixed" clbitcrack as in using an older build like 0.30, or a fixed version of 0.31? I just tried 0.30 and while it finds all keys ok, it's about half as fast as 0.31. I have 3090's so I believe I'm stuck using clbitcrack until the misaligned address issue is fixed for these newer cards that require the newer CUDA.




https://github.com/brichard19/BitCrack/issues/256
Is the fixed I tried before and showed execution of in the above quote.
If I wasn't such a nerd, I would send you the .exe, but I discourage people of doing that. You should really build it yourself for max. security.

The .31 isn't faster. The calculation is wrong, so it looks faster.

So apply that fix to 0.30? And the speed improvements from 0.31 is due to the fact that it's not working properly?
But like they said, the speed on .31 is incorrect...
The crazy thing is, Brichard is a good programmer. He built a kangaroo program using OpenCL that is actually compatible with all my cards and actually works on the 30xx series card. and the speed is accurate. The bad thing, it's not open sourced so I can't make mods to it to suit my needs.
Maybe he doesn't keep working on bitcrack because it has lived its shelf life, meaning brute forcing the keys from 64 on up (the original reason he built the program, was for the puzzle/transaction) is next to impossible without all hands on deck. Who knows...

You can just apply it to the master branch. It will work fine.



For now, I am just testing that clbitcrack is working properly by using some of the public test keys against their known keyspace (same list of test keys others are using here). As others have complained, 0.31 has an issue finding private keys and it reaches the end of the keyspace without finding the keys. 0.30 seems to find all keys using the same list, but for me it's half as fast as 0.31 (when I let it run on a private list of addresses where the keys are unknown). With my 3090 using clbitcrack 0.31, I get about 1050MKey/s whereas with 0.30 I get 600MKey/sec. But why run 0.31 if it's never going to find any keys with the known issue.

Another issue people had was clbitcrack would find some of the known keys but not all of them (versus not finding any). Not sure what version has that issue or if it's just with certain GPU's, but it something else I am testing for too.

So I guess my question is, is there an actual fix for clbitcrack 0.31 that doesn't have any of these issues but still has the speed improvements that comes with 0.31? Or, if there's another program that's currently developed and supports 3090's and would work better, please let me know. I am basically just trying to recover private keys from a list of known wallet addresses by incrementally scanning the private keyspace. I know this is exactly what Bitcrack does, but not sure about the others, i.e. VanitySearch, Kangaroo, etc

Fixed code for the RTX would require a full re-write of the existing CUDA codes out there. We investigated && concluded it would be too costly to do, as our devs could be earning way more in that same time.  Wink
There are minor openCL improvements possible, but didn't had the time to check up on them.

We're also in the progress of building a website that publishes all spaces we've ran, so others could do lottery & run other spaces. 'cause yolo.

What are you searching for? Are you searching for #64 (btc puzzle/transaction 64 bit) or just random keys?

0.31 would not find those test keys for me either using clbitcrack. Anyone have a link to 0.30 precompiled so I can test? Can't seem to get 0.30 to compile under Windows.

You just need a fixed CL version. The forum/issues tracker is full of solutions;

Code:
clBitCrack.exe -o output.txt --keyspace 60F4D11574F5DEEE49961D8577307:60F4D11574F5DEEE49961DA609AC5 1NLbHuJebVwUZ1XqDjsAyfTRUPwDQbemfv

0.31 would not find those test keys for me either using clbitcrack. Anyone have a link to 0.30 precompiled so I can test? Can't seem to get 0.30 to compile under Windows.

Can anyone try to test clBitCrack.exe  on you PC/laptop  last version 0.31 (Improve OpenCL performance)

I just looked at those commits leading to 0.31, and while I don't know much about OpenCL, it seems that the only major change he made is to replace the representation of 256-bit numbers from an array of 8 32-bit bits to a struct with an array of 8 32-bit bits (and some loops were unrolled). I don't see how this is supposed to make it run faster because it should've used a larger word size like a 64-bit cl_ulong, which would reduce the number of load and store instructions by half. Nobody uses 32-bit platforms any more so there's no reason to keep a 32-bit version around and therefore constrain all the arrays to use 32-bit ints as well.
