Vega Finally Unleashed! Fine-tuned performance and power consumption in a single chassis.

GTX 1060 resets itself from Overclock - only one card in the mining rig of 6 GPUs

Hi all,

I have a reocurring issue with my mining rig. Every time I restart the system the mining rig runs at full capacity at 145 MH/s. [6x GTX 1060] After a while (usually few hours) GPU no 1 drops in hashrate by 25% and the rig's hashing power drops to 140 MH/s. [see picture attached ]

I am using MSI Afterburner and I can see one of my GPUs returning to default setting randomly and I have to set it manually to my overclock setting. Once its back to my overclock settings it will stay there for a few hours and reset itself again. If I leave it running the whole rig becomes unstable within 24 hours and I have to restart the system again.

What could be causing it? Bug in bios/afterburner? I tried different overclocking software.

Is there a way to program restart every time the hashrate drops without having to do it manually?






Many thanks. K

    it's probably a heat issue, it reaches the temp limit and then resets... try taking the oc lower and monitor more

    What is the memory of ur GPU ? If micron, above 750 on mem clock will crash. Depends on the individual gpu. Reduce the core to -100 and reduce the mem to 750. Run this setting. If it crashes. Reduce the mem in decreasing order of 10s and see. U should find a sweet spot somewhere in-between. If its stable at 750 increase in 10s and find a sweet spot.

    U can check the memory manufacturer in GPU-Z.

    As the above user said. Add some external fan like a table fan and blow on the hottest running card and reduce the temp.

    Try lower memory clocks. You don't have to keep it there, but it's almost certainly causing your issue. Running 1060s above +700 mhz is aggressive. Not saying it isn't doable, just that you're really pushing the limits of the hardware.

    The settings will reset when the card fails. Like shifty said, you should lower the memory clocks or try upping the power.

    I had this problem with one 1070 ti card (total of 7 in rig). The solution was to close Afterburner after the overclocked settings had been applied to all the cards. If I kept Afterburner running the one card would lose its overclocked / power settings. Try that, just apply the settings, start mining and then click on the close button to exit Afterburner. You also may want to dial down the overclocking a little if you are pushing the cards too hard.

    I found this in dept guide from some guy on Anorak, how to tune your GPUs for max hashrate and low voltage. It fixed my 580's from 24mh/s to 30mh/s

    It's a really big and detail guide, check it out. I'm sure it would help if you go through it.
