Some sort of Gigabyte 3GB overclock edition (retired miner), had some crashes before, but now it was constantly every 10 - 30 min. while gaming. Tried to figure out what it is/was - first stumbled across this - https://www.overclockers.com/forums...undervolting-guide-for-79xx-and-R9-280X-cards but instructions were unclear, although supposedly I managed to flash bios (gpu-z didnt reflect changes). Anyway ended up with EVGA OC Scanner - default settings, boom-crash. Next EVGA OCS with MSI Afterburner and that did it. Underclocked both core and memory clock and while EVGA OCS running started to increase them, core clock had no effect, but memory clock was the key. It was increased from downclocked 1000 to 1300, 1400, 1500 (which is default) and the latter caused a crash. So the conclusion/solution is to downclock memory. Just putting it here, that someone with similar problems could find a possible solution instead of grabbing new card.
