It seems I am getting a self-test failure with this hashmode, but not with others. I am not sure what else to try.

hashcat64.exe -m 9600 -b
hashcat (v5.0.0) 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.

OpenCL Platform #1: Advanced Micro Devices, Inc.
================================================
* Device #1: Tahiti, 2393/3072 MB allocatable, 28MCU

Benchmark relevant options:
===========================
* --optimized-kernel-enable

Hashmode: 9600 - MS Office 2013 (Iterations: 100000)

* Device #1: ATTENTION! OpenCL kernel self-test failed.

Your device driver installation is probably broken.

Works fine for me:
