GTX 1070 + GTX 980 = ??? - bikes - 08-25-2023
GTX 1070 was running hashcat fine in an old desktop. Added a GTX 980, and hashcat couldn't see either device.
Code:
$ hashcat --benchmark [26/26]
hashcat (v6.2.6) starting in benchmark mode
Benchmarking uses hand-optimized kernel code by default.
You can use it in your cracking session by setting the -O option.
Note: Using optimized kernel code limits the maximum supported password length.
To disable the optimized kernel code in benchmark mode, use the -w option.
clGetPlatformIDs(): CL_PLATFORM_NOT_FOUND_KHR
ATTENTION! No OpenCL, HIP or CUDA compatible platform found.
You are probably missing the OpenCL, CUDA or HIP runtime installation.
* AMD GPUs on Linux require this driver:
"AMDGPU" (21.50 or later) and "ROCm" (5.0 or later)
* Intel CPUs require this runtime:
"OpenCL Runtime for Intel Core and Intel Xeon Processors" (16.1.1 or later)
* NVIDIA GPUs require this runtime and/or driver (both):
"NVIDIA Driver" (440.64 or later)
"CUDA Toolkit" (9.0 or later)Current state: Host was downgraded to Debian 11 with a fresh install. Successfully installed CUDA toolkit + NVIDIA driver.

$ lspci | grep -F NVIDIA
01:00.0 VGA compatible controller: NVIDIA Corporation GP104 [GeForce GTX 1070] (rev a1)
01:00.1 Audio device: NVIDIA Corporation GP104 High Definition Audio Controller (rev a1)
03:00.0 VGA compatible controller: NVIDIA Corporation GM204 [GeForce GTX 980] (rev a1)
03:00.1 Audio device: NVIDIA Corporation GM204 High Definition Audio Controller (rev a1)Perhaps this is more of an NVIDIA issue than a hashcat issue; though I'm curious about:
1. Why hashcat stopped seeing the GTX 1070?
2. Why CUDA + NVIDIA don't see the GTX 980?
RE: GTX 1070 + GTX 980 = ??? - slyexe - 08-25-2023
Could it be a dead PCIE port? If you remove the 1070 and only place the 980 does it work? Either the card is dead, the PCIE slot is dead or theres some unknown factors that I am unaware of at this point.
RE: GTX 1070 + GTX 980 = ??? - bikes - 08-25-2023
Both PCIe slots are working. However, the motherboard abruptly died so it's now a moot point.
