I am trying to optimize one of my RX 580 8 GB cards overclocking settings. I have numerous invalid shares with these settings in the hive OS:

Core clock: 1050
Core voltage: 900
Memory clock: 1950

What is the best way to go about optimizing a card for it overclocking when it's showing several invalid shares?

There are many reasons why a GPU might get invalid shares. Sometimes just turning off the rig and powering it back up can make the invalid shares go away. Another reason is if you overclocked too much and undervolted too much. If so reduce your core clock or increase your voltage.

Another reason can be the straps that you used. I used the 1500mhz straps into higher strap memory clocks and it gave errors on some GPUs, so I used other available custom straps for that GPU. There is a thread somewhere on here with custom straps for RX series cards for Hynix and Samsung memory. Other times there can be nothing you can do but keep getting invalid shares for certain GPUs. I had that happen before. As long as its a small ratio, I ignore them.

Which brand card do you have?

I have many brands of 580 and all except the pathetic XFX can be overclocked to 2100-2150 without incorrect shares. I'm on windows though.

Increase the voltage to 920 and observe.

RX 580's run most stable at about 950mV

I run Sapphires on 1150 Core, 2200 Mem and 945mV

its most likely you got lot of memory  error, try use HWINFO64 and check memory error rx 4/5 series should showing that

try for 24 hours check if no memory error, use other memory timer and dont push to much on memory clock even miner not crashing isnt always good sign

if no memory error then maybe miner software or pool connection been problem

Have many rx580s 8 gb
Settings range from

Core clocks 1120 to 1150
V 800 to 845 mV

Memory 2050 to 2100
850 mV
