Hey all - this morning my 1080 Ti FEs got delivered and, as you might expect, I'm eager to get gaming with them. After installing them and setting up SLI, I started playing Watch Dogs 2 - only for the game to crash after about 30 seconds, taking my system with it and forcing a reboot. After trying again and getting similar results, I tried Fallout 4 (with the HD texture pack) - this lasted longer, but still rebooted my system after 5 minutes. I double checked that the old drivers (I'm upgrading from an AMD R9 280) uninstalled correctly and they seem to have done so. Almost every component in the build is less than a week old - brand new PSU, motherboard etc etc. There are no problems at all in general usage and - until the game crashes - it runs flawlessly, solid 60FPS etc etc. I'm inclined to think it's NOT temperature related - the hottest card was 81C in Fallout 4 (71C when it crashed), and only 45C in WD2 when it crashed (accoring to SpeedFan). I'm going to head out for some work but I'm interested to know if there's anything I've missed. Full specs (since it's been a few years since I was round these parts): Intel i7-7700K 32GB (4x8GB) DDR4 @ 2133Mhz 2x 1080 Ti FE (using Asus HB SLI bridge) ASUS ROG Z270E Motherboard EVGA Supernova 850G Thanks in advance for any help!
