multi GPUs configuration/overclocking

[kryptyk]

Hi there,
I am wandering if anybody can share tips on configuration/overclocking of a multi GPU rig running nvidia GPUs in an Ubuntu Linux environment to improve performance or enhance hash-rate with hashcat?
I have it running smoothly, but I think I could speed things up a little by overclocking.
Any tips or link to tutorials will be appreciated.
Many thanks.

you can use

Code:

hashcat -I or hashcat -II

to see your backend devices and their numbers(capital letter i of information)

then use -d command to specify which device number you want to use

then use --session command to run multiple instances of hashcat, binding any session to specific device number

then use -O (capital letter o, not zero) for kernel optimization

if you use wordlist, you split your wordlist so you can use it for many instances of hashcat

then use -w (workload profile) to speed up the recovery process
