Performance problem with hd 7970 - raTTein8787 - 04-03-2013
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/product/?cid=1&gid=3&sgid=1157&lid=1&pid=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.

What are the optimal values -n and -u?

Try -n 80 - u 4096
Then -n 160, but watch the temperature.

Then -n 160, but watch the temperature.
