hashcat Forum

I've did some test with hashcat v4.2.1 with an AMD RX480 GPU on Windows 7 with the latest AMD "Adrenalin" driver ( win7-64bit-radeon-pro-software-adrenalin-edition-18.7.1-july9.exe ) just to make sure it's working and we do not need to change anything to the driver recommendation on the main hashcat page. 

Some guy on IRC mentioned to change it which is the reason I wanted to verify what he said.

I haven't used AMD hardware on a Windows box (and much more important, the AMD original driver) for quite some time, but I can confirm everything still works out of the box.

Here's a screenshot from afterburner with hashcat running in benchmark. Each time a new benchmark (for a different hash mode) is starting the graph reset, the GPU utilization ideally goes to 100% and the core clock stays on maximum.



Here's some robust benchmark output:

The most interessting fact is that the windows driver is clearly faster than the linux driver (MD5 @ Linux: 10,203,053,705 vs Windows: 11,981,034,475). I think this is related to the power limit that I can set to 50% on windows using afterburner. Important! Do not confuse setting the power limit with overclocking. Setting the power limit just effectively disables the power consumption throttling. This enables the benchmark to run smooth on the 1266 Mhz boost clock and not to jump around crazy to save a few watts. The 1266 Mhz is the stock clock setting for this GPU. Damn AMD, why can't you just give us such a quality driver for Linux!

The HD7970 came out in 2012. It's too old and is likely a problem with the driver. It also usually helps to ask for help, not demand it.

The first screen with PMKID says about the full performance.

It is already reported on Github but the cracking seems to work and at the speed seems to be as expected.

I don’t know what you’re expecting. The card is too old and reposting the same information won’t solve it. Remove the 7970 from your system or skip it in Hashcat and you won’t see the warning any more.

This is the advice of the student, but not the developer. Excuse me.

The map is supported by the manufacturer to this day.

Look at the screenshot you posted. It literally says the drivers are the problem. The card is too old.

These are tests version 5 BETA.

Version 4.2.1 works fine.
