Hello community
I need your help
Guys i use Sapphire RX 580 Nitro(plus) 4GB Hynix Bios for my cards for 1 year
https://mega.nz/#!gHoGBKDZ!QhNE4j8oZ4VkdiM3xtsHeBoTRiouo75o9UVAOJbh6Lg
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 ?

Check PSU, how many cards do you have on it? What are your settings (core, memory, mV) for mining, I presume ETH? Are you using them in the same conditions (winter, summer)?

I do not know how to test the PSU, it should be okay
It's rm750x Corsair Current harvesting 300w 2x cards
Setting : cclock 1150 mclock 2050 mvddc 875
The bios is already modified with the memory clocks and the cpu plus the voltage in 875 in memory

I minning ETH
Same conditions summer/winter

Can I change memory values? even when it's modified in bios?
If so, how? Do I have to use the command in the main configuration?
Or it would be enough to change in Simplemining OS / overclocking menu?

Do not use the command in the main configuration. It's enough if you change them in SMOS. Try 900mV for the core into the overclocking menu, see how it's going... if it's stable go back to 875mV. See if the issue appears again.

I tried Core undervolt 900 and after about 30 minutes reboot.
