oclHashcat v1.36 slow on Windows 10 - rico - 08-17-2015
Hi all,
Yes, I've been a silly boy, jumping into Windows 10 x64 before knowing much about it (and before there's a driver for my old Soundblaster too apparently!).
Anyways, I've installed the new GeForce 355.60 driver for Win10 and I've just noticed that WPA is waaay slower than when I was on Windows 7 x64
I used to get about 47000H/s but now only 32500H/s ! That's a big difference.
Here's a slightly older benchmark I had lying around (Win 7 x64):
D:\Network\hashcat\cudaHashcat-1.35>cudaHashcat64.exe -m 2500 -b
cudaHashcat v1.35 starting in benchmark-mode...
Device #1: GeForce GTX 760, 2048MB, 1137Mhz, 6MCU
Hashtype: WPA/WPA2
Workload: 4096 loops, 32 accel
Speed.GPU.#1.: 47594 H/s
Now today it's:
D:\Network\hashcat\cudaHashcat-1.36>cudaHashcat64.exe -m 2500 --benchmark
cudaHashcat v1.36 starting in benchmark-mode...
Device #1: GeForce GTX 760, 2048MB, 1137Mhz, 6MCU
Hashtype: WPA/WPA2
Workload: 1024 loops, 32 accel
Speed.GPU.#1.: 32606 H/s
Started: Mon Aug 17 21:01:58 2015
Stopped: Mon Aug 17 21:02:14 2015
Anyone else experiencing this or is there just something wonky my end?
PS: cudaHashcat64.exe -m 100 --benchmark
Hashtype: SHA1
Speed.GPU.#1.: 534.3 MH/s
Is this also slow for a superclocked GTX 760 or about right?

No, me too on Netntlmv2 hashes. Half the speed as compared to Win 8.1. Most likely the new drivers though I suppose, but reverting to an older driver isn't an option in Win 10. I'm waiting for 1.37 to hope that fixes it, if I need it more urgently I'll boot off usb into Linux.

Well whadda ya know, v1.37 to the rescue. Nice work atom!

No luck here. Benchmarks still crash.
cudaHashcat-1.37>cudaHashcat64.exe -m 5600 -b

Device #1: GeForce GTX 980 Ti, 6144MB, 1076Mhz, 22MCU

If I run -a 3 crack it does run but nowhere near the speed I would expect (570 MH/s max per card) on a single hash.

Ah, I see what you mean:
D:\Network\hashcat\cudaHashcat-1.37>cudaHashcat64.exe -m 5600 -b
cudaHashcat v1.37 starting in benchmark-mode...
Device #1: GeForce GTX 760, 2048MB, 1137Mhz, 6MCU

ERROR: cuStreamSynchronize() 702
Windows 10 also popped up a message saying display driver stopped responding. However, on my 3rd and 4th attempts:
D:\Network\hashcat\cudaHashcat-1.37>cudaHashcat64.exe -m 5600 -b
cudaHashcat v1.37 starting in benchmark-mode...

So try again, michelin.
I also ran all benchmarks (-b option only) and got as far as "SMF" before display driver crashed again:
Hashtype: SMF > v1.1
Workload: 512 loops, 256 accel

Similar story with device driver crashing occasionally. Seems a bit random. It's not like its the only thing broken on Windows 10 mind!
I will just dual-boot or downgrade.

I had the same issues as you when I upgraded from 8.1 to 10. At first it would work but then crash. There are 2 things you need to do:
1. Create, edit copy/paste and then double click (install) the .reg file and delete it after successful import: https://hashcat.net/wiki/doku.php?id=timeout_patch
2. Uninstall any old NVIDIA drivers and install the newest only (Get rid of PhysX and User Experience programs too unless you want them)
For reference, I am getting around 30,000 WPA2 hashes per second on the GeForce 840M with 355.60 driver and v1.37
