Well I am not sure how this is possible, but applying 1.5mm thermal pads on all the memory chips resulted in the left hand side memory chips to not come in contact with the thermal pad. And when I replaced all of them with 2mm, my GPU die wasn't getting contact with the heatsink, hence the...
You were right ! I had placed 1.5mm pads on the memory instead of 2mm. Now my memory temps are at 72c during mining. But now I observe that my GPU hotspot is at 104c compared to 95-96c previously !
I replaced the all the thermal pads completely with thermalright 12.8 W/mK on my aorus master 3080 rev1 and still see memory temps hitting 110c while mining. -200 on the core, 70% Power Limit. Not sure what the problem is. 3mm on the back, 1mm and 2mm on the front.
