Very Slow Keepass hash-rate
#1
Hello, I am trying to run hashcat on a hashfile from a keepass database.  The first time I ran it, I was able to start cracking a test database file at 100 kH/s, using the latest hashcat beta software (I am writing this as of April 6, 2020).  I don't know if this is of importance, but at some point, because I forgot to change the time it takes for my computer to go to sleep, it, well, went to sleep.  When I turned my computer on, it was running at a much slower rate, I don't remember the exact rate, but it was in the 100-1000 H/s range.  Any ways, I didn't think much of the low rate, I thought it just had to do with the fact that my computer went to sleep while it was hashing, so I tried with the database that I did want to crack, but it was running at about 300 H/s with -w 3.  Using Windows 10, AMD Radeon RX 5700, driver is latest update to RadeonSoftwareAdrenalin2020.  I've already tried both beta and regular versions of hashcat (the regular version doesn't seem to ever work for some reason), I've tried uninstalling and reinstalling hashcat program, uninstalled and reinstalled the driver for my GPU, used AMD's cleaning software and reinstalled the driver.  Any suggestions that might help?

Here is what it looks like when I run hashcat on the hashfile.

Code:
C:\hashcat-5.1.0>hashcat.exe -a 3 -m 13400 -w 3 etherium.hash
hashcat (v5.1.0-1764-g008072eb) starting...

One last thing I should say, my GPU is running at 95-99%, so don't think its that.

Thanks!
