unstable gpu overclock?

[Blackhole890]

gpu: rx 570 sapphire nitro+

custom bios? yes

gpu clock plz: 1244mhz to 1400mhz

memory clock? 1750mhz to 2090mhz

volt? yes, -96 (the lowest that msi afterburner could set)

did you switch the bios buttom thats at the top of your gpu logo? yes, to the left

 

issue? So sometimes, not always, when i set this config and i start the program to mine ethereum, my screen gets monochromatic and later, it restarts and sets the stock config... Max temp is 66ºC. Thoughts?

Voltage is too low. Just leave it stock.

I would agree with Jurrunio and just leave it stock unless you really want to live dangerously. Then try something like -48 or -40 if you want to under volt, it is more likely to work although with an overclock under volting is less likely to work than stock.

 

Basically anytime you move from stock settings you are going to be in an experimental phase, try, crash, change settings, crash, change settings, run for a while, crash, change settings, run longer, crash, change settings...until you find the balance between settings that work for you and run long enough for you.

but if i leave at stock, it goes from 29.100mh to 28.500mh + 15 w more power consumption... And now is set to -72, seems stable for now

 

and its just sometimes, not always but sometimes... around 20% chance to trigger a crash

Yep that's about what I said, try slightly higher voltages until you find the level of risk you are willing to live with.
