Hello everyone! Recently I had the opportunity to put together a 6x 1070gtx mixed brands.
When I use hashcat piping one of the c++ scripts found on here ( https://hashcat.net/forum/thread-6170.html ) the GPU usage is not 100% all the time. I'll explain better with pics.
HW:
-6x 1070gtx
-CPU i7-4790
-MOBO H81 Pro BTC R2.0
-RAM 2x 8GB 1333 MHz
SW:
-Ubuntu server 16
-nVidia driver 384.90
-hashcat 4.2.1
If I run:
./ua | hashcat64.bin -m2500 -w4 lollo.hccapx
I've notice that the GPUs go from 100% to 0% and vice versa all the time as the pics shows. I guess that is the CPU not able to create fast enough the wordlist?
Any idea on how I can improve the performance of my rig?
Also if I run:
hashcat64.bin --stdout wordlist.txt | hashcat64.bin -m2500 -w4 lollo.hccapx
I get something way worse. But if I run it in straight mode it will keep a nice 100% on all the GPUs at all the time.
If you need more info just ask me, I will reply as soon as possible!!
Thanks in advance!
