R9 280X speed
#1
Hi everyone!

I've got ~42,000 H/s while bruting WPA handshake on Sapphire R9 280X. Is this normal for 280X? Honestly, I was expecting a little better Smile

Or maybe there is some way to increase speed? I would appreciate any help.

P.S. Changing "Accel" and "Loops" settings didn't help.

According to http://golubev.com/gpuest.htm you can get 100k.
What is your cmd line ?

A common error is that people try to crack multuiple handshakes at once. Look at the status output if its trying to cracking only 1 salt, not more

I'm getting ~125 kH/s running Ubuntu 14.04 64bit (one handshake at once).

Good to know. I didn't overclock, don't think this has much sense. (nm size from 28 to 7 and architecture improvements would be much better Big Grin)
