Hi all,

Been racking my brain for weeks trying to figure out why my 2080 ti's crash mining grin31...I have a couple machines with 1080ti's and they run wonderfully, but this machine has 3 cards, 1 x 1080ti and 2 x 2080ti's and within a min or so of firing up the miner one of the 2018ti's crash - fans go to full bore and 0's show in afterburner.   The machine is quite powerful with an 8 core cpu and 64 GB of RAM.  I've got VRAM set to 80GB, my machines with 6 x 1080ti's runs great with 70GB...Power supply is probably on the edge at 850 watts, but I monitor the usage and run the cards at 65%..And the wattage stays below 700 ish on the machine...I've uninstalled drivers, swapped cables, tried different drivers, lowered the clocks...Any tips on what else I could try would be greatly appreciated.  It will mine x16r for weeks without an issue...It's not just this miner, it's all miners for grin31, but I posted here because this miner is the best which means this thread probably has some real smart folks...
