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!
