I've only installed my 3900x today but have since had the following all evening whilst trying to play pubg... WHEA_UNCORRECTABLE_ERROR As posted in another thread, the CPU was at 50 degrees or under showing all cores at 4175 according to hw monitor when it happens. Totally standard setup, no overclocking just xmp on my ram. I have recently been seeing fairly frequent crash to desktop (on 2700x pre upgrade) with a pubg crash log generated. Usually I attribute this to the game, but it might happen 3 to 4 times in an evening. This above however is happening anything up to 15 minutes into a game... Temps are low, rarely go above 40 when really pushed, no artefacting etc, just bsod or even black screen followed shortly after by rebooting. All drivers are up to date, with all mobo and chipset drivers, windows is a fresh install (1903). GPU not overclocked, just running 120% power limit as it boosts to 2126mhz regardless... Is my GPU dying or could this be ram, what's the best way to test and check before painful RMA process?
