Hi i saw a strange issue and dont know what is source of my problem.
When one hashcat instance is running all is fine, but when run couple instance (all in one time or pause rest) fans are freaking out :/
i work on 4x 7970 ghz stock closk without any OC.
Now working on sha1 with speed like 5000MH/s (1 instace) temps about 60-70c but when run second instance card are ut to even 83c and speeds are 2500+2500 so gpu load is same.
And another most importants think, couple time fans on one gpu are STOP. hashcat shows 15% fan speed but i see that fans are stoped. Try manualyy run them at 100% in catalyst control panel and it dont work. But when i kill hashcat process fans automaticly start :/
I dont know where is problem, drivers? hashcat?
Iam usind win7 x64
AMD catalyst 14.4
4x7970
Any idea where is problem ?
