Mining rigs power combined

[Zilim]

hello everyone , this is my first post here
i have a question and i hope to find an explanation if there is an answer
i have 150 GPU farm , 20 rigs total
is it possible to use all of my farm to brute force sha256 hashed string into its original form , the chars are  0123456789abcdef and the lenght is 64.
how to make this happen 
do i have to do it in every single rig ? and if so how i make sure non of my rigs repeat the same guess so it wont waste time ?

You have to set up a server hashtopolis and connect all the machines.

i am noob , i will try to set up hashtopolis and run all. but what command i should use in hashcat to crack a 64 long string that contains only those charset (hex) ?

is it possible for hashcat to decrypt 64 hex string provided the hashed version ? 64 chars and using 150 gpus at once (all rx3090) .. whenever i test on my pc i get integer overflow detected ..

No, you won't live long enough to break that, never mind the other technical limitations.

64 hex chars is 16^64 possible combinations, which is about 1.157 x 10^77 combinations. That's very close to the estimated number of atoms in the observable universe.

The reason you get integer overflow from hashcat is because hashcat will only handle up to 2^64 combinations in a mask attack.
