Maybe it should be like that, but I'll ask the experts.
When the dictionary attack starts, the speed is excellent, but after some time, I see that the speed drops by about 6 times, if it was 1.2 million per second, then the output will be about 240 thousand.
maybe some additional options need to be written in the command or the dictionaries need to be optimized somehow, what do you advise.
and yes, my dictionaries are from 10 GB and above, some are 80 GB

Yes, it does happen. Which hash mode?
Md5 or shall usually doesn't drop, if btc or eth then yes, could drop to 1/6th of start speed

ok, thanks
Is it normal on NTLM hash? Maybe the card temperature affects it, 70 degrees, it is impossible to reduce it lower

If on win, install AFTERBURNER and undervoltat cards aka create profile with same gpu speed but 75mV lower voltage.
On Linux I don't know how to undervolt.
But it is possible that hashrate drops.
Try to add -O (not zero but O) to hashcat string

-O in my practice it increases the speed, but for some reason it does not find the password that I know in advance, since I did tests, it is very strange why this is so.
I did not reduce the voltage, since in my opinion this will reduce the power of the cards and I will get an even lower result, all I did was set the "power limit" from 100 to 90 so that the cards do not go beyond 70 degrees.
Thanks for helping

have you already removed this option and others to stop the cards?

4090 and undervolt does not necessarily means reducing hashrate. Because modern cards have multiple limits one ot them is max power consumption and if clock speed is high, voltage is high, and combine power is greater than xxxW then it reduces clock speed but not voltage because of stability. But all cards are over engineered and if you reduce only for 50mV, power is slightly less but clock speed remains high. In modern overclocking power down=overclock
Try it.
Also, are cards over risers 1x or are on risers fullX Speed?

1x because the full one would not reach the length
OK, i try change power
