Gtx 1070 issues!!!!

[CloudbaseJ]

Hello

So I just bought a new 1070, bringing my total up to 4.
I plugged the new one in and all was good for 5 hours, then before bed I checked it and it had frozen.
I down clocked the memory a little and 're booted, now all I get is a black empty box which is claymore on a black screen. I 're boot but get the same blackness.
I tried resetting the cmos but no change I also unplugged the new card but no change.
Any help would be greatly appreciated.

Cheers

What power supply are you using? 4x 1070 cards could be pushing it pretty hard.

I'm using a corsair ax860 but it never draws more than 450w from the wall

That seems kind of low for a rig with 4x 1070s, plus everything else.

What did you use to underclock the cards? Something like MSI Afterburner? Or did you do this within Claymore's miner?


Try unplugging the PSU from the wall, wait about 20 seconds, then plug it back in and attempt to boot. If that fails, try swapping out the card in the primary x16 slot and use a different one for your display.

I used msi afterburner but I monitor power usage with a kill a watt.
I'll try your suggestions tomorrow. Thanks
Fingers crossed

I have now tried all the above with no fix.
Strangely though if I unplug all gpus apart from one then I can get to the mobo splash screen. Here I can see the wheel turning, like windows is trying to load but nothing happens.
Any ideas? Cheers

What did you overclock it to?

[CloudbaseJ]

It gets weirder! On my monitor I see the splash screen but on team viewer I see the blank screen with an empty claymore box?! I can open the start menu to reboot but that is all

What did you overclock it to?

I have been running this OC for a month now with no issues. Its +750 mem -50 core on 58% power

I should've known! Faulty riser, which I think messed up my drivers. All sorted now.
Thanks for the help
