Modernize hashcat - pbies - 01-10-2025
Will there be new version accepting AMD CPUs like 9950X(3D) or nVidia RTX 4090 cards (both CUDA and OpenCL)?
Can hashcat be polished to use these hardware? And when?
RE: Modernize hashcat - penguinkeeper - 01-10-2025
Hashcat can already use that hardware, I use it on a 4090 regularly

I am getting some errors beside that it goes and do what it is supposed to do.
Maybe range of changes is small enough to make hashcat accept this hardware?

What errors are you seeing, specifically? Also, just make sure you're running on the latest, 6.2.6 and not any particularly old version, although even 5.0.0 would probably run a 4090 and 9950X, although I think it's an environment issue and not a Hashcat version or hardware problem

Yes, I am running latest beta.
I am getting errors about AMD drivers and CPU itself.

What errors, specifically? Could you copy-paste them into here, please?

hiprtcCompileProgram is missing from HIPRTC shared library.
Support for HIPRTC was dropped by AMD Adrenalin Edition 22.7.1 and later.
This is not a hashcat problem.
Please install the AMD HIP SDK
RE: Modernize hashcat - penguinkeeper - 01-10-2025
Ah yeah, those are mostly harmless. As it says, some core parts of AMD's drivers that Hashcat relies on were removed, so you can install the Intel OpenCL Runtime (Even for an AMD CPU) to have the option to utilise your CPU for cracking (this isn't recommended). For your CPU's integrated graphics (again, not recommended), you can install ROCm or the HIP SDK. Your 4090 should be working perfectly fine, it's just that your CPU and iGPU can't be utilised, which isn't advised anyway as both of them combined probably won't even be 10% the performance of the 4090 lol

I wouldn't state this as several hashes perform better with a CPU over a GPU. Also if hashrate is available why not take advantage and use it? Not everyone has access to hashing rigs and if its adds an extra ~10% that could change your attack time significantly.
One thing to recommend is NOT using laptops for long term cracking sessions as cooling is the most important aspect and laptops are severally crippled in that department which could lead to hardware failure.

This generally isn't true, even with EPYCs, it's extremely rare that any CPU would beat a 4090. It's only very uncommon hashes like a very high memory-tuned scrypt but generally on the latest beta, 4090s do well enough that CPUs struggle to keep up. I agree that they are very occasionally helpful but not for 99% of use-cases
> Also if hashrate is available why not take advantage and use it?
It can cause slowdowns with other, more powerful hardware. The CPU gives the GPU work, so often you can slow down your GPU if you also use your GPU. For example, my total hashrate in -m 0 -b with both CPU and GPU is 28.4GH/s but with just my GPU alone, it's 34.2GH/s, so not only is it consuming more power, it's also slowing everything down unnecessarily. The problem with iGPUs is both that because the workload distribution difference is so great, either the powerful card or the iGPU can get stuck waiting around and problems with autotune only double.
> Laptops ...
Idk where this came from but yes I agree
