Miner Problems

[CitizenEra5ed]

Good morning fellow miners, I thought I had posted this yesterday but cannot find it now.

My miner has a problem. It has 5 x 280x graphics cards but since it crashed on Chistmas morning, there is now only 1 card showing up.

I was mining Zcash using the Claymore version 9.1 and it had been mining for about 4 days before it crashed (not unusual as it seems to crash every few days and a simple reboot normally gets everything working ok again - but not this time)

The specs of the miner are :- Windows 8.1 pro 64 bit, 5 x Sapphire 280x, 2 x 1000 Watt power supplies (1 powering 3 graphics cards and 1 powering the rest of the rig and the other 2 cards), 4 gig ram, Gigabyte GA -990XA-UD3 motherboard, large HDD (cant remember size and miner is off at present), Sempron processor (again, cant remember exact model), 15.12 graphics card drivers.

Everything is about 2.5 years old and has mined all sorts on and off in that time so there is nothing wrong with the specs of the rig.

I uninstalled the graphics driver with the DDU program and reinstalled it.

Just wondering what to try next??

Any ideas greatly received

Cheers

Chris

Put a monitor on one by one and check risers?

[CitizenEra5ed]

Thanks for the reply. Ive plugged a monitor into them all and im only getting output from 1 card. The fans are spinning on them all but not outputting any video. What could be wrong with the risers?

Risers could be failing, also why dont you try another version of windows? I personally like win7 for mining

Remove all cards and test them 1 by 1.

This will give you answers ... either all cards work... or some cards has problems.

If all cards work, then you move to next step:

Risers ...

Test all risers 1 by 1 in the port you know already works.

If all work. Next step would be the pci-ports.

Change OS ( win7 64 bit is acceptable), check the risers, try another driver ( you should use Crismos v16.10.1 or v16.10.2)

That is the good instruction.
