Just 20 kP/s with 4x1080 Ti

Hello.

Initial data: Bitcoin core wallet btcrecover.py --wallet wallet.dat --performance --enable-gpu --global-ws 131072 --local-ws 1024 Starting btcrecover 0.17.8 on Python 2.7.14 64-bit, 16-bit unicodes, 32-bit ints btcrecover.py: warning: --performance without --no-dupchecks will eventually cause an out-of-memory error Wallet difficulty: 211,554 SHA-512 iterations Using 4 OpenCL devices: GPU GeForce GTX 1080 Ti GPU GeForce GTX 1080 Ti GPU GeForce GTX 1080 Ti GPU GeForce GTX 1080 Ti / 2621440 elapsed: 0:02:15 rate: 19.41 kP/s

I read that it's possible to have about 25 kP/s from each GPU. What I do wrong?

211,554 SHA-512 iterations

That is a lot if memory serves me correct.. try with local 256 aswell though.

Could be your CPU bottlenecking.

That's considerable better than the 1.85 kP/s I can get on my single R9 390 with the same iteration count (and as @kost123 said, the iteration count is a bit on the high side - it means the wallet was created on a reasonably fast PC, and will be slower to try passwords against).

If you use only one GPU, is the speed reduced to about one quarter (add the --gpu-names 1080 option to limit btcrecover to just one)? If so, then everything is probably working as intended.

Didn't see this post, by the way this is my my config, been try --global-ws 262144 and some other lower setting but only get around 13.3 kP/s, --global-ws 200704 --local-ws 1024 is the best setting I found so far.

19.41 kP/s with 4 cards seem way too low.

Tried your settings. Now it's 1kP/s passwords more - 20.6 But I think it's because I have wallet difficulty: 211,554 SHA-512 iterations, and you just 78,362 SHA-512 iterations

More 1kp still nice anyway, and ya, my wallet made long time ago, since 2014 - by the way with that wallet and two 1080 Ti:

@Chococat Can you try a btc core wallet with ~55k SHA512 for a speed comparison? ...thinking of snagging some 1080s for a job. If possible speeds for 1 and both. If your bored, a 105k SHA512 wallet too =) Thanks!

[gurnec]

FYI an easy way to "create" a wallet for testing different iteration counts is to grab the bitcoincore-pywallet-dumpwallet.txt wallet file from this directory and change this line to whatever you'd like to test.

[rterwedo]

In case someone is reading this later... with 2 overclocked 1080 Ti SC2s, on a wallet of 55k SHA256 iterations. Its ~37k (pypy)-42k / sec (pregen pwd list).

[marfalz]

what about running it on a 16core 32 thread..what speed will i get?

[mikejnpc]

was there a fix for this as with 4x3090s im getting rate: 12.41 kP/s
