Has anybody managed to remove the limiter while using a x16 to x16 riser? My stupid fucking motherboard has the 2 pci3 slots too close to each other and my 2 3060s won't fit at the same time.

Works on x1 risers if you plug in a hdmi dummy plug. Nvidia 470 beta drivers can handle 6++ 3060 cards in the rig mining fullspeed without any problems (with 6 hdmi dummy plugs installed).

The annoying part is that the offending region of memory is 32-bit aligned

Vector instructions need 16byte alignment.
In bitcrack sp-mod #5 ~66% of the time is used to multuply numbers. Pretty stupid algorithm. With tensor cores enabled, might push the hashrate abit.

Doesn't work. The 30 series problem is code related, not a PTX compile issue.

I will receive my first 30 series card in a week or so. Will fix then.

All four mods are not working in 30 series GPUs Sad waiting for your 5th mod Smiley

Can you try #5? Does it work?
1266  Bitcoin / Development & Technical Discussion / Re: BitCrack - A tool for brute-forcing private keys on: March 26, 2021, 11:28:36 AM
For me #4 and #5 finished the same search in the exact same amount of time, so no difference on #4 vs #5 on my side  Huh

Try to let the program choose the launchconfig automaticly. And solve a harder puzzle. The program is optimized to solve 2^64 - 2^160 keys

And I don't care about speed at all; I care about results...in time.
On the one hand, of course you are right. But we are discussing a bruteforce program here. For bruteforce, the only indicator of the quality of work is important - it is the number of keys/addresses per second.

Here is sp-mod #4 in vankraken mode: 7 seconds to solve puzzle 39 (4 seconds to set up the poins 3 secs to solve). Note that the speed is only 278Mkeys/s because I only set up 100 starting points.

1269  Bitcoin / Development & Technical Discussion / Re: BitCrack - A tool for brute-forcing private keys on: March 25, 2021, 09:08:02 PM
if the private key is close to 2^65 random is faster, if it is closer to 2^64 linear is faster. given that you start the scan at 2^64.

Random will also increase the probabilty that the number interval hasn't been scanned by others.

The random code is based on:

https://github.com/BoGnY/BitCrack/commit/7cd546f3f965b4be51d6beb237e5b3640f75678f

With a few bugfixes.
1270  Bitcoin / Development & Technical Discussion / Re: BitCrack - A tool for brute-forcing private keys on: March 25, 2021, 07:28:16 PM
sp_ is it normal to take A LOT longer when using -r?


puzzle #39:
cuBitCrack.exe --keyspace 4000000000:7fffffffff 1EeAxcprB2PpCnr34VfZdFrkUWuxyiNE
           
Will scan search for a private key between 2 numbers:

 274 877 906 944
 549 755 813 887

Without the -r parameter the scan is performed linary like a counter  274 877 906 944,  274 877 906 945...

The solution key is

323 724 968 937

Bitcrack will check 48 847 061 993 seeds
with -r Bitcrack will faster if the private key is above  274 877 906 944 + (549 755 813 887- 274 877 906 944)/2
1271  Bitcoin / Development & Technical Discussion / Re: BitCrack - A tool for brute-forcing private keys on: March 25, 2021, 05:44:10 PM
And I don't care about speed at all; I care about results...in time.

But still no binary or sourcecode to look at.. Show me some code, and we can talk again.
1272  Bitcoin / Development & Technical Discussion / Re: BitCrack - A tool for brute-forcing private keys on: March 25, 2021, 05:32:03 PM
(up to around 44 bits), random is faster, in my tests.

Up to around 44 bits database is faster. The point is that why do you care about the speed in low bit problems? 2^64 and up is more interesting. My mod is based on bitcrack and yes it is scanning bruteforcing all of the solutions. That might be a littlebit stupid, but stupid solutions can still solve problems with enough hashing power. My fork has a random mode. Run with -r --random.
1273  Bitcoin / Development & Technical Discussion / Re: BitCrack - A tool for brute-forcing private keys on: March 25, 2021, 05:13:25 PM
Man get outta here. Precomputed keys in a database is not the same as vanbitcracken.

No binary, no sourcecode how can we tell the difference? How do we know that vanbitcracken doesn't use a sql database?
1274  Bitcoin / Development & Technical Discussion / Re: BitCrack - A tool for brute-forcing private keys on: March 25, 2021, 04:40:04 PM
It is slow? Yet my program found the key in 44 seconds but yours took around 10 minutes?  

I have a program that find the key in 1ms. It is written in sql. Local database. Here is the sourcecode. It is OpenSource:

select privatekey from compressed_bitcoinadresses where adress="122AJhKLEfkFBaGAd84pLp1kfE7xK3GdT8";


Quote
So you are telling everyone how fast your mod is but it takes your mod over 10 times longer to find the same key, with a better GPU than the one I am using?

I just showed you my 1ms opensource program (puzzle #39). You can show me yours and we can compare them.
1275  Bitcoin / Development & Technical Discussion / Re: BitCrack - A tool for brute-forcing private keys on: March 25, 2021, 08:55:54 AM
For the #39, it took the 1060 6GB card exactly 44 seconds to find the key.  Start to finish = 44 seconds, with 1 card. Grid size of 3072x512.
sp, is 44 seconds good on an old 1060 card?

No it is slow. should run under 100ms. You can retrieve the precalculated keys from https://privatekeys.pw/ . Since the answer to the puzzle is already known and can be precalculated.

Back to the speed of my bitcrack implementation.

puzzle 39:  2^39  = 549 755 813 888 possible combinations

with a speed of 400 000 000 (400MKeys)

puzzle #38: 274 877 906 944 / 400 000 000 = 1374 seconds (around 12minutes)
puzzle #39: 549 755 813 888 / 400 000 000 = 1374 seconds (around 23minutes)

With 400mkeys and solving puzzle 39 You would expect the program to spend 12-23 minutes. The hashes used to find the solution is printed in the miner window and the speed can easily be verified. Bitcrack sp-mod is working. I see that my fanclub is present already. I welcome you all. Go crack some keys.
The next version will come with more speed.

1276  Bitcoin / Development & Technical Discussion / Re: BitCrack - A tool for brute-forcing private keys on: March 24, 2021, 10:41:45 PM
Here are some more problems:

Puzzles:
#39: 122AJhKLEfkFBaGAd84pLp1kfE7xK3GdT8
#40: 1EeAxcprB2PpCnr34VfZdFrkUWuxyiNEFv
#41: 1EeAxcprB2PpCnr34VfZdFrkUWuxyiNEFv
#42: 1L5sU9qvJeuwQUdt4y1eiLmquFxKjtHr3E

How much time does your programs use? How many keys where scanned? What was the launch config of the program?

#39 with sp-mod #4 takes less than 10 minutes with 1 gpu
1277  Bitcoin / Development & Technical Discussion / Re: BitCrack - A tool for brute-forcing private keys on: March 24, 2021, 09:58:07 PM
With Vanitysearch version 1.19, I get 1100 Mk / s with 3 gtx 970.
with your version I get 690 Mk / s

Vanitysearch is not  the same as bitcrack. To get the vanitysearch speed multiply by 6..

- causal search in a range
- set the search bits

In bitcrack sp-mod:

For random search use the -r option or --random
1279  Bitcoin / Development & Technical Discussion / Re: BitCrack - A tool for brute-forcing private keys on: March 24, 2021, 09:15:50 PM
1060 6GB card, 25 seconds total time, start to finish.

Start to finish tests is not a good way to compare 2 programs in a simple problem. My program use time to setup a good grid in order to solve the harder  problem.

If I remove ptx and support for other cards than compute 6.1 I gain 10 sec's++

Successfully launched with -b 68

on the 2080ti can you try with:

-b 136 -p 512

Then increase -p until out of memory. like -p 768  -p 800 -p 900
