Hello community

Guys i use Sapphire RX 580 Nitro(plus) 4GB Hynix Bios for my cards  for 1 year

But  last weeks many times reboot my rig  cause  this message
Rig is rebooting due to system error. It could be caused by too much overclock/undervolt.

Always was  works great (30+ MH/s + undervolt), but now my rig reboot  after couple hours
I can not explain it
This ROM has a recommended driver 17.30.1029

But I can feel that something has changed on the Simpleminning side.
And now my ROM does not work as before
All components are in order (stock rom works without failures)
Does anyone have any advice for me to solve it?
Is there any new ROM version for Saphire RX580 4GB(elpida) cards that work correctly with Simpleminning OS ?
