too slow ntlm - RocketTwice - 11-03-2021

HI, i have win10 + rx 5700 xt , hashcat 6.2.4 but speed is extremely low .

When im using bench it shows me

Code:
-----------------------

* Hash-Mode 1000 (NTLM)

Speed.#1.........: 40515.0 MH/s (65.72ms) @ Accel:2048 Loops:1024 Thr:64

looks ok, but on real ONE hash it shows me

Code:

coolers on fire while benchmark is running, but silence when bruteforce attack.

What is that, can anyone help me?

RE: too slow ntlm - ctrl - 11-04-2021

You are using Pure Kernel. Try -O instead:

hashcat.exe -O -m 1000 -a 3 hashes.txt maskfile.hcmask

RE: too slow ntlm - RocketTwice - 11-04-2021

Hi, Pure kernel even faster, you can check this in my first message. Just updated drivers to latest -21.11.1

Result for 8k hashes:

I dont know whats going on,stuck with test (

RE: too slow ntlm - atom - 11-04-2021

It's exactly what to expect if someone uses -S, because you will be hit full effect from PCIe bottleneck. Just remove the -S which makes no sense in context -a 3 anyway.

RE: too slow ntlm - RocketTwice - 11-04-2021

Refreshed page to tell you guys whats wrong and...your message is here. You are totally right. Im trying to add params one by one and all is ok now.
without -S, as u told.

Im happy now =) much more better to see
