benchmark and real work big difference - blaster666 - 08-06-2023
Hello, i got rtx 3070 wich shows speed of 58kH\s on benchmark for 3200 bcrypt mode
While testing on real dictionary with like 5 billion strings, i am getting this output:

Could this error message be reason of the error:
Successfully initialized the NVIDIA main driver CUDA runtime library.
Failed to initialize NVIDIA RTC library.
* Device #1: CUDA SDK Toolkit not installed or incorrectly installed.
CUDA SDK Toolkit required for proper device support and utilization.
Falling back to OpenCL runtime.
* Device #1: WARNING! Kernel exec timeout is not disabled.
This may cause "CL_OUT_OF_RESOURCES" or related errors.

RE: benchmark and real work big difference - blaster666 - 08-06-2023
UPD.
I have installed CUDa 12.2
Speed has increased, but a little , from 1400 to 2000h\s
But that is anyway far far away from benchmark 60k hashes
Please help
RE: benchmark and real work big difference - blaster666 - 08-06-2023
And the strange thing is that, while hashcat is running, i could see in task manager, that CPU and GPU are loaded for 1-2%
GPU usually - 0%
RE: benchmark and real work big difference - blaster666 - 08-06-2023
I am also entering -w 3 , -w 4 parameter. It dows not help. Speed is low, and nothing lagging
RE: benchmark and real work big difference - blaster666 - 08-06-2023
On usuall md5 i ve got 9kh\s
that is so slooow

Sounds like you're dealing with a number of different issues. For one, bcrypt comes in variable "costs" or "difficult" hashes, meaning your hash may be a much much slower setting than the benchmark hash, which is cost 05. This is the second number in the bcrypt hash so you can check your hashes to tell. On top of that, the benchmark process runs an ideal bruteforce, which is a mask attack with good workload. Other attacks may have less than ideal workloads and this show less than ideal speeds.

what real speed should i expect for worlist brcypt brutoforce. for 1 hash, in case benchmark shows 58000
I hope it is not 30 times lower like i have now
Plus, i could see in task manager that my PC almost has no load
GPU always 0-2%
CPU same
I really hope it could be faster, even though these are not ideal conditions

second number in hash is "2"
RE: benchmark and real work big difference - blaster666 - 08-06-2023
hashcat.exe -m 0 -a 3 example0.hash ?b?b?b?b?b?b?b -w 4
for this command which should have give 60% of GPU benchmark speed, i am getting 15 000 mh\s, however it should give 60+% of benchmark speed, expecting about 22-24000 mh\s .
Could you help me to spped up bcrypt hashmode somehow?

Could someone assist me please? Could I boost bcrypt wordlist method somehow?
