So good ccap is 70 for your hardware.
Did you get the same error message with ccap 70 ?
Could you try with cuda 10.0 ?

I made clean OS installation (Ubuntu 18.04 LTS) and now it works with cuda 10.2 drivers without any problem. Do you suggest better command for my system? I feel speed should be more ... ?

10.2 really? can u tell me the exact driver version? maybe nvidia patched something like a bug or so.. i would give it another try then..

did you also run -check and it was without errors ?

did you edit cuda config or used the one from source?

Also, my laptop now makes a quiet sound while scanning, something like tac-tac-tac-tac-tac-tac every 5 seconds

That sounds like your HDD's "actuator arm" (slider head) tapping the disk (platters).
If it's an SSD, then it must be a barred fan that can still slip through or something because there are no other mechanical parts that can produce a "tac-tac-tac" sound.

The latter could slow-down your GPU because of cooling failure.

it does sound like a HDD working, exactly like that tapping sound, but my laptop actually has SSD.
also it gets extremely hot underneath after just 30 minutes so I guess it is a barred fan then

Haven't been using the program for a couple of weeks, today gave it another try.
What I noticed:
Right now it is 20 Mkey/s GPU 20 Mkey/s and it periodically goes down to 10 / 10
two weeks ago it was 100 / 100 Mkeys. Why such a downgrade, what does it depend on?

Great:)

You can only use wildcard characters ? and *:

Try to play with gridsize, ex: -g 640,256,640,256,....
On the benchmark by DaveF, for a Tesla V100-SXM2-16GB we have 1.815 GK/s per board.
You have 40GK/s , so 2.5 GK/s per board, not so bad...

Hi,
Yes there is an issue with Cuda 10.2 (both on Linux and Windows), it works fine with 10.0.
I didn't try it by myself but some users already reported this issue.

Edit: May be it is a different problem there, when you compiled what ccap did you use ?
Could you try to execute VanitySearch -l ?

I compiled with ccap 75

-l results is below:

I've tried with ccap 70 also ...

Hi,

First of all I need to say I really amazed on calculation speed of your program. I am trying to use it with Tesla V100 device but I am getting the following error;

Cuda version is 10.2 , Ubuntu server 18.04.4 LTS

command is :
./VanitySearch -gpu 1sdfa

result is:

Because I'm testing something important and I need to know how to get WIFI from HEX

It's WIF (Wallet Import Format), and AFAIK, vanitysearch doesn't have a converter command since it's already included in the result.

If you want to know how, it's not that complicated, you just need some tools for SHA256 computation (Hash online tool) and Base58 encoder/checker (Base58 online tool),
Then, follow these steps:

1. Get the private key hex,
Sample: 4116A49CA05407397C159D9F8EFC32064E3165466173AA26D21DA11A169BF7FD
2. Insert 80 at the start of the prv key and 01 if you want the compressed prv key WIF (do not insert 01 if uncompressed).
Sample Compressed: 804116A49CA05407397C159D9F8EFC32064E3165466173AA26D21DA11A169BF7FD01
Sample Uncompressed: 804116A49CA05407397C159D9F8EFC32064E3165466173AA26D21DA11A169BF7FD
3. Get the SHA256 Hash of the string above (as HEX not text):
Sample Compressed: 47aa53130b00c52fed1cf223a04bce7a2d083f111ed5b3dcb6a2a23f06dc3c78
Sample Uncompressed: 1a75a1d066dcc407ac94a8e07042bb3fcf97f0c41b9d23c2ec9b54fc75b8e2c4
4. Get the SHA256 Hash of the SHA256 Hash above:
Sample Compressed: 78a9182fdc5389e180d08702ac1ec0707221c861b08a7c0e3da56465c01104f9
Sample Uncompressed: 7b376ba10130e9ae74f447847fbc5ae1c076d42efc932e8dc30ca64401835c8f
5. Get the first four bytes of the Double SHA256 hash from step4 (the first 8 characters), that'll be the 'Checksum':
From Compressed: 78a9182f
From Uncompressed: 7b376ba1
6. Then insert the result of step5 after the result of step2:
Sample Compressed: 804116A49CA05407397C159D9F8EFC32064E3165466173AA26D21DA11A169BF7FD0178a9182f
Sample Uncompressed: 804116A49CA05407397C159D9F8EFC32064E3165466173AA26D21DA11A169BF7FD7b376ba1
7. Encode to Base58 the strings above and you'll get the WIF format:
Compressed WIF: KyQEYWYtkttfuaMGBqoBqtpkUJ4M8yHKVtQ3pBkXChBXbraGiS2z
Uncompressed WIF: 5JJxBK2LRu5umY7rfFgTvfvsBGCBTGvYNx9Pqkfrtb2Un7BrosE

If you need to do this automatically, just paste it on bitaddress.org's "Wallet Details" link.

How to convert (in vanitysearch.exe) using one command privKey in hex hormat to WIF?

Uhh, why?

WIF private key is already included in the result, it's the second line "Priv (WIF)".
Just don't include "p2pkh:" when copy-pasting, most wallets do not support that address type prefix.

Does the

-t 0

Get added to the above bat command line?

It depends on your preference, add that if you do not wan't to use your CPU.
Any additional argument after the @set command=vanitysearch -stop -gpu line should work.

Wait, I just found out that the 50-100 consecutive results of the output files are the same address, need further testing.
@Jean_Luc What do you think is the issue?

Hi,
Did you find the issue ? I didn't test your script yet.

Not yet,
The issue is when using an input file with multiple lines of the same prefix, eg: (test.txt)

Code:

1test
1test
1test
1test
1test

The output file will have multiple lines of the same addresses and private keys, eg: (result.txt)

Code:

Address: 1testx1nayKrQadrXAXyvLQUVeai6tpCt
Priv (WIF): p2pkh:KyQEYWYtkttfuaMGBqoBqtpkUJ4M8yHKVtQ3pBkXChBXbraGiS2z
Priv (HEX): 0x4116A49CA05407397C159D9F8EFC32064E3165466173AA26D21DA11A169BF7FD

PubAddress: 1testx1nayKrQadrXAXyvLQUVeai6tpCt
Priv (WIF): p2pkh:KyQEYWYtkttfuaMGBqoBqtpkUJ4M8yHKVtQ3pBkXChBXbraGiS2z
Priv (HEX): 0x4116A49CA05407397C159D9F8EFC32064E3165466173AA26D21DA11A169BF7FD
PubAddress: 1testx1nayKrQadrXAXyvLQUVeai6tpCt
Priv (WIF): p2pkh:KyQEYWYtkttfuaMGBqoBqtpkUJ4M8yHKVtQ3pBkXChBXbraGiS2z
Priv (HEX): 0x4116A49CA05407397C159D9F8EFC32064E3165466173AA26D21DA11A169BF7FD
PubAddress: 1testx1nayKrQadrXAXyvLQUVeai6tpCt
Priv (WIF): p2pkh:KyQEYWYtkttfuaMGBqoBqtpkUJ4M8yHKVtQ3pBkXChBXbraGiS2z

The latter worked as intended since I've set to loop the command instead of using that input file.
