It's plugged directly into the mobo. I don't think it's a physical issue, since it was working fine before the driver update to 16.12. Strange that it works for you though. I'm using windows 8.1 as my OS and it's my normal desktop PC.

Is the second slot on the mobo or a riser, if it is a riser sounds like it's a bad riser.  If its on mobo does it have a third slot you can try. Slots on mobo s do go bad also.  Also double check the seating of the cards, I've messed around in a rig and jarred one and they want connect. Also, you could try driver 16.5.2, it has been rather stable.  I'm running 8x 280x with 16.12.2 with no problems.  Also, what os are you using and is the rig used for anything else.

Yes, I did

Do you think these spikes can be the reason why my rig freezes? I will describe my problem a little.

I have a 7970, a 280x and two fury nitros. During the last couple of weeks I have been trying to run my system stable with no luck. Freezes can happen at any time after starting to mine. Sometimes minutes, sometimes hours.

Rig specs: Asrock 970 extreme4. Sempron 145. 8GB ram. EVGA 1300 G2. Sapphire 7970 ghz edition, sapphire 280x vapor-x, 3x sapphire fury nitro OC. Tahiti cards undervolted on bios, fiji cards on msi afterburner. No OC on furys. Win 10. 12.6.3. CM 11.1.

First I changed all risers to v6 ones.

Next I upgraded the processor to athlon x2 because I noticed that I was getting less hashes when MSI afterburner was on and I thought the system would be more stable.

After a couple of days more I changed the mobo to asrock h81 pro btc with celeron 1840.

Still no luck.

I thought that the power was insufficient so I added a corsair rx1000 linked with an add2psu device.

No luck, freezes persist.

Changed EVGA to corsair hx1200i. This psu is powering mobo, raisers and tahiti cards.

Nothing changed.

I stopped undervolting. Still same freezes.

One fury died the day before yesterday. No fans, not detected in win 10, not detected on ubuntu, mobo not booting when the card is alone.

I changed risers again to the furys.

I used separate cables for each riser.

I powered the offending fury card with one cable for each connector. Still the same.

I tried catalyst 15.12. Same effect.

Sometimes I see 511 degrees in the fury card on CM log prior to freeze, sometimes it just stops hashing without any error and the watchdog doesn't restart the miner, sometimes all 4 cards go to 0.000 hashing without any error, sometimes after gpu reported incorrect temperature 511°C.

I'm already out of ideas.

Any hint, anyone?

Chain is stuck at block 50534 27 minutes now!  Everything is frozen...

Difficulty of 1577367 proves too high for our GPUs.

Did you use DDU to uninstall the existing drivers before installing the new drivers.   

Yes I'm working on new version with speedup for all cards. Need a few more days though.

Hi,
I need your help.
I have 2x 280X cards and I was using the v8.0 miner (because that's what the pool I'm using directed me at).
Everything was working fine, until I upgraded to the newest amd driver 2 weeks ago. After that the miner would get stuck in a loop at random times, telling me that there was an issue with the gpu.
I've downloaded v11.1 and tried that, but the problem got worse. The miner will get stuck immediately after startup.
I downgraded my driver to 15.12 hoping that would fix the problem. It works more or less now. I can only use my primary card, in the upper most pci-e slot.
For diagnostics I took that one out and started the miner with the other card in the second slot. I immediately got an error message, telling me that no opencl gpu was found.
Is there a way to get my second card running again? (It will neither work with the v8.0 version that was just running fine before the driver update)

Im using Claymore Dual Miner Monitor. In miner i use -mport -80 option to disallow control from outside. Just to watch rig stat.

Problem with app is that it dosnt run on background sometimes.

BR/ RAKOT

And of coz you should have static ISP IP set and port forwarding on your Internet router

is there a way to monitor my rings remotely from my phone? at this moment I use time viewer to periodically log into a loos standing pc on the netwerk. The network is firewalled to reduce the chance of being hacked so connecting directly to each rigs is not possible. 

I see there is an app on play store but not sure if it safe to install and connect to my rigs
