Can it be caused by a driver issue?

If not, bad riser(s)?

Bad power supply filtering???



EDIT: It occurs on my 12x 1080 Ti rig

It has always happened when I pushed the cards memclock too far.

Perhaps that's your issue,  you must reduce memclock or either decrease the undervolt, increase power limit.

Bios is the last thing I would check (maybe your timings could be wrong too but just think about it when everything else has been tried).

Drivers, obviously first.  I normally just reload the machine as I can clone it fast.  If that's not it then normally bad riser if that don't fix it the card just can't handle being OC.

I modified the opening post, adding the information about the cards: they're nvidias (my AMD rig runs fine).


As for the O/C, I'm currently a safe +140 core, +160 mem at 85 TDP

I'm having this issue sometimes with my 5-nvidia mini rig with asus rog strix x370f and ryzen 5 1600 cpu. It seems the mobo doesn't hold all this pci-e lanes full on duty. Setting all pci-e to gen 1 helps a bit but not totally.

In my experience that blue screen can mean ANYTHING. From bios settings, to bad drivers, to some windows settings. I will even switch the cards to different PCI lanes.

Sometimes after days of getting nowhere, I'll just reinstall Windows and make sure I have the bios settings correct before starting.

[Amstellodamois]

I've reinstalled Windows once.
The drivers once more.
Rechecked the mother board bios settings.

Is there a utility that would show me what's happening at the GPU-level? Memory erros, BUS usage, that kind of stuff?

[dagarair]

pull a card at a time until problem goes away.

[Amstellodamois]

I've been running 6 of them the whole night, gonna try with 3 more and see.

Probably bad overclocking settings. When this happens you usually have to lower clocks (both core and memory).
Are you using the same brand/type of 1080ti's?

Well, I'm not crazy with my O/C:

Yes, they're all the same Gigabyte

I had same problem, spent 3 weeks trying to figure out. I solved my problem by installing nvidia drivers instead of unzipping, going to device manager-driver update-browse. Nvidia cards seem to need full install, not just naked driver itself. You can untick all the crap, just leave tick at DRIVER.

Either bad risers or drivers.

That's what I've done every time :-(

Sometimes, the miner stops.
Sometimes, I get a BSOD.
Sometimes, I get this :

Will check if it's always the same GPU.

This problem is caused by drivers issues, you're absolutely right. I usually reinstall drivers in safe mode or replace atikmdag.sys/atikmpag.sys files (works for ATI for AMD graphics cards).

[Amstellodamois]

Again, I'm using only Nvidias on that rig.

On a hunch, I moved my PCIe extender from a port to another. It's been working well for an hour now.
