Guys i am having two GPUs, 3060ti Founder edition and 3060ti Gigabyte edition. Gigabyte one was older on which i have mined for 3 months with no issues. However after mounting it on riser, an error is coming up at random times. Sometimes after 2 hours, sometimes after 2 days. I was using PhoenixMiner. Error goes like this, "hwmc GPU2: unable to get GPU fan speed- GPU is lost (15)" and then it restarts the PC. The riser used by me is "https://www.amazon.in/PiPlusTM-VER009S-Powered-Adapter-Extension/dp/B08YXHPZXL/ref=sr_1_4?dchild=1&keywords=piplus+riser&qid=1632508986&sr=8-4". Please check. I am a newbie therefore dont know much technicalities. However i have powered riser and gpu from different PCIe cables from psu. I will try increasing fan speed but the issue is that it will run for a day or two nonstop and then suddenly in every 2 hours i get this error and miner reboots. Today it restarted the pc at 6:57, 8:57, 10:57 and so on. This is one log file for your reference,

after this mining is continued for 30 seconds and then it restarts the PC with windows failure of NO CARD DETECTED. Is the problem with riser? I tried changing the position of GPUs i.e. replaced two GPUs with one another and still the problem persists. Now i switched to Trex miner. My OC settings are Power limit 70, core clock tried a whole range of 0,-200,-300,-502, mem clock 900,950,1000,1100,1150,1200 fan speed such that it stays around 67 C. After rotating GPUs i think problem is isolated with riser and its power cables. I use 850 W Antec HCGGold PSU. The power cables for riser and GPU are both separate.

I think its defective riser but not able to see how after restart problem vanishes. In fact i ordered this riser yesterday, https://www.amazon.in/Tapia-V009S-Plus-Indicator-Extension/dp/B097R24JFB/ref=sr_1_5?dchild=1&keywords=riser&qid=1632540537&sr=8-5. Should i cancel it and reorder? This is the another 010s riser i could find https://www.vedantcomputers.com/riser-extender-ver0010s-plus-8-capacitor-ultra-stable-extra-led-16-into-to%20-1-into-power-pcie-80cm-usb-3point0-cable?search=riser.

Did you find any solution ?

Yes i changed the riser and it works flawlessly. However for your reference, when i switched to Trex miner and modified some code as follows, it worked with quite less errors.

--gpu-init-mode 1 --keep-gpu-busy --no-nvml
