Hash speed - bbcjared - 05-31-2019

Hello, 

Is there's a way to speedup Bitcoin/Litecoin hash processing? 

I'm running dict attack and getting ~3000 H/s on GTX 1060.. soooo slow.. 

Any way to improve speeds ? 
Code:
hashcat64.exe --session=crackstation -m 11300 -a 0 my.hash wordlists\realuniq.lst -o cracked.txt

RE: Hash speed - philsmd - 05-31-2019

try to add -w 3 or even -w 4

you could get even more speed with rules (but of course the overall runtime could increase too).

so the correct answer is:
1. more dedicated/clever attacks (specific to the target hash, better rules and dictionary, smaller is sometimes better Wink )
2. more/better GPUs


update: wait you are cracking 18 bitcoin hashes. omg. that's also a reason for slower speed because of more salts !!! 17 unique of 18 total is also very strange, I would investigate this a little bit why 2 hashes have the same salt. that's not normal for bitcoin hashes, I guess

Yeah, good catch with 18/17 .. weird.. 

Thanks for your answer.

Quick update , having this run with just one hash/solt and -w 3 increased speed by 100 H/s so about 3300 H/s now, but still sloooow. Seems like reducing number of hashes to work on does not impact performance much..
Any other advises besides obvious "moge GPUs" appreciated .
Thanks.
