You need only Phoenixminer. I use the recent drivers, there's no point for blockchain anymore. (AFAIK)

You need to mine individually for several minutes to know the overclock for each one and take notes.

After every cards is on, figure out what is gpu 0,1,2,3,4,5 by starting each one individually (gpuz will tell what card is on if you are a remote controller), if your cards are really identical, gpuz will not help and you need to be present. Set fan to 90 and use your eyes.

Then just put the numbers of each one and your command line will look like this: (only 7 cards here).

"-FANMIN 70,50,50,70,90,70,50 -FANMAX 90 -CCLOCK 1250,+150,+150,1250,-400,1250,+150 -MCLOCK 1800,+400,+400,1800,+300,1750,+400 -CVDDC 760,0,0,760,0,760,0 -MVDDC 0 -TT 75 -HSTATS 2 -PROTO 4 -POWLIM 0,-33,-33,0,-40,0,-33 -straps 2 -gser 1 -coin eth" - Go to phoenixminer page here and read all commands, there's a lot of cool things

A rig with only AMD will be simpler

Obviously for overclocking HIVEOS is hella easier but have its own problems.

I have one RIG with 20.11.2 and two using 20.12.1 (for non specific reason), I don't know what driver is the best, i'm returning to this world now and i need to re-learn.

Windows crash is often overclock, one of them is above its capacity. Incorrect/reject shares are a hint.
High temp in one card may causes crash, the card reduces their clock automatically. Low virtual memory, ram memory or disk space may cause cashes when DAG is rewritten. Another software running in the background like windows update may causes crash too. You should be able to use your browser while mining without crashing, this is a good test.

Sorry for bad english.

Better English than mine mate, thank you for good advise.

I have been running my system pretty much the way you explained. I have given number to each gpu, and in the rig they stay in their order so i know gpu4 where it stays and it could be in different place on phonixminer so i can find it easily but when you updade the software this order changes and takes several hours to figure out again. Which is not a problem this is how we learn and improve i guess. Softwares like simpleminer makes it easier maybe but once this setting is completed then there is no point for simpleminer.

Just wondering did you mod bios your amd gpus and what hash rate do they give you?

What software update? I don’t recommend keeping updates on. My cards only change numbers when I install a new card but most keep their pci bus number. Those cards belong to 3 different people, so I need to identify and configure three different miners with their wallets, it's a nightmare.

All are bios modded, i live in a very hot country with high electricity costs, so i don't push my cards too hard. I manage my and my associates' cards from a 30km distance, I need to play safe too.
There are seven 580 in total, the good ones do around 30.7, the bad ones (powercolor) do 29.6.
two 5700 doing 54.2, one at 53.3
