Hi
Windows 7 64-bit, just installed.
Video Driver Catalyst 13.1
oclHashcat-plus v0.14
Video card - SAPPHIRE HD 7970 3GB GDDR5 OC with Boost (http://www.sapphiretech.com/presentation...1481&leg=0)

When working with WPA/WPA2 speed 73000-75000 and GPU load 75% no more.The site in the table is written: PC1 - WPA/WPA2 (PBKDF2) - 133k c/s.
Why do I have such a low speed? Can anybody explain this?

Thanks in advance.

Thanks for the tip. Previously, I used hashcat-gui64 without -n and -u settings. I tried a CMD and get the result 141k c/s.
What are the optimal values -n and -u?

Try -n 80 - u 4096

Then -n 160, but watch the temperature.

Of the many combinations I settled on this: -n 80 -u 512.
