Hi guys, my RX480 mining rig is having a problem here.
2 out of 6 GPUs hang after 5 mins of mining with Claymore miner, please refer to the screenshot below.
The rig is powered by 2 750w psu.

I’ve tried reseating the risers and lowering the OC, but the result is the same.
Previosly the rig was running at a steady rate , after i relocated the rig, i have this problem.
Any advise is appreciated.

Two 750W power supplies should be enough to power your rig so we can, probably, rule out power problems (as a check use a power monitor on each supply - just to be sure).

A couple of things you could try.
Run the rig with only each of the 'faulty' cards individually to check if there is a problem with the cards - disconect every thing but the card under test.
Strip the rig down completely (leave CPU place) and re-build it, it's the hardware equivalent of "Have you tried switching it of and on again?", you never know what may have been knocked out of place during the move.



Thanks brother.
I’ve temporarily remove the 2 “faulty” cards for now and will try your method in awhile. Will give an update soon.

The memory size is 6144 MB, memory type is Hynix.
My current OC setting is Power Limit 75%, Core Clock +50, Memory Clock +300, Fan Speed 65%.
With the current OC setting, the cards are running at GPU Clock 1566 MHz, Memory 2152 Mhz. (Based on GPU-Z)
The default clock is 1506 Mhz, Memory 2002 Mhz.

The problematic fan that runs at 100% automatically has the lowest temperature even it is running at 65% like the other cards.
So i dont think the fan switch to 100% due to overheat.


I Got 4 1060 6gb Aorus with samsungs.

I was beating about 3 weeks with strange instabilty wit h my rig. It works OK then BAM! cpu gets loaded up to 80-90% and hash rate drops. Cards seemed ok.
I reinstalled win 7 and win 10 dozens of times. tryed dozens of drves versions and settings.

The problem was EASY - too much overclock!
If you are used to artifacts and freezes due to ooverclock - so in in mining it is strange instabilty. First  sign is MSI AB or any system proces start to use 60-80% of CPU even if miner is stoped! Reboot and lower OC by 5 pints  backwards. watch your rig again until it is stable. then do another -5 and this is you stable OC.

Second sign of GPU error - fan speed in Claymore i 0% i logs.


And dont OC the CORE. ETH needs only Memory OC. Core can be undeclocked for coolnes..

I got 50% power limit, -200 core, +765 Memory. I get 98.2mh by x4 GTX1060 rig power consumtion it 472wh!

You're so on point !
I started to wonder, how come everytime i launch my AF, even with my claymore closed, it takes forever to launch the AF.

Let me try your OC setting. I will come back with the updates.

Thanks alot !

Hello everyone, unfortunately my cards are pretty bad.

Whenever i try to downclock the core, the miner stuck at the 6 cards detected.

So my current setting is 0 core, +300 memory. reaching to about 20.5 MHz per card. Power consumption about 622 watt for 6 cards.

The miner still crash sometimes, but will auto restart.

Is this a good OC setting ?

No one likes Hynix memory on nVidia - it has too high latency and does not hold very well overclocking. It's a surprise to know that 6GB GTX 1060 also use Hynix chips, I thought they carry only Samsung and Micron.
Your fan goes 100% because of driver error, that is caused by unsustainable overclocking settings. Since you overclock by MSI Afterburner, check-out the Synchronize settings across similar cards and define lower clocks for the problematic GPUs.

Hello, thanks for your advise.

So i should untick the option in MSI Afterburner to sync the same setting to similar cards.
And define lower clocks to the problematic GPU?

Like probably running at core clock +30? Memory clock +200?

Looks like drivers reset because OC too high.  Dial back the OC.
I second that. When overclocking settings are too high, I get "NVML error: cannot get temperature" and "NVML error: cannot get fan speed" in Claymore's log file, and the hashrate becomes null on that GPU.

chanyewhau,
Ethash algorithm is more memory-intensive than Equihash and memory instability manifests itself faster. What is the exact memory frequency - check GPU-Z or another Afterburner skin, that shows the actual frequency? Try to run the miner at stock clocks and PL 80. Sometimes it happens that cards do not hold even a 10% clock increase.
BTW, what memory size and type is installed on your GPUs?
Fans running at 100% will not shorten the life of your GPU, though the fans might fail sooner due to increased mechanical stress (mainly the bearings run dry and might jam).

Hi guys,

I'm mining with MSI P106 x6.
However, 2 of my cards are not able to run at the fan speed that i've set in AF, which is 65% fan speed.

It appear to be 65% for the first 5 minutes when the miner first launched, then it turn to 0%, sooner it turn to 100% fan speed for 1 of the fan.

My concern is will running 100% fan speed on my GPU kill the card faster ?

As it generates more noise and consume more electricity, can someone share how can i fix this ?

Back then, when i was mining zcash with EWBF miner, i don't have this problem.

I've attempted to reseat all the risers. It appears to b fine for 2-3 hours. after that it went back to normal for the same GPU.

Someone please help. Thanks all.
