I spent ages last night trying to get it solid - so far it only crashes in games not stress tests or benchmarks. I put my 1080 back in and issues went away.
Went back to the 2080ti and installed an older driver - 417.71 and so far, touch wood, it's been stable. I am concerned however that a driver could have been causing my bluescreens / crashes - the product should be past this stage now driver wise surely!.
Have told overclockers in the customer services forum that I will report back tomorrow.
I need some advise really what would you guys do? This has been a pain in the ass, I've tried loads, PC is in bits from changing cards + watercooler out from the 1080, removed overclock, updated bios, all sorts.
Thanks,
Alex
