Mix GPU rig crashing with 3070

[ShakKevlo]

Fairly new to mining. I’ve been adding cards as I find deals.

3060ti
3060
3060
1070
1080
3070

The 3070 GPU has two 8pi. Power supply

Using trex.

For 2 days everything was working great. Then all of a sudden the mining stopped. I rebooted and the system couldn’t get the 3070 back up. Kept getting an error. I tried to turn off the OC. It would work fine for a short time and then err. Is it a power issue? I have a 1250 PSU.

Thank you

are you using locked core clocks on all the 30 series cards? are you using the pill?
