Why is happenin? Look pictures please. Cpus cores and threads not work together. My english bad sorry but all hardwares new. Motherboard msi meg ace z390 - i9 9900k - corsair 150i pro - msi rtx 2080ti x trio. ssd m2 is 970 evo plus and ssd sata is evo 860 . ram is 16gb corsair 3200mhz. My psu corsair rm850x(2018) What am I missing? I use windows 10 pro. But one thing is when I download msi motherboard chipset, All lookin well outside but when I click Intel(R) PCI Express Root Port #1 - A338 or another port it says in event: cannonlake hsystem - the device didnot start. And why them all says cannonlake. It need coffee lake ? When I press Intel(R) PCIe Controller (x16) - 1901 and it's for rtx 2080ti. Event say: device uploaded(skylakesystem inf.) What is that? Why My all chipset devices work with cannonlake or skylake. I tried reinstall windows but always this happenin. Another side I use UPS 1400VA I think its 750W . This ups can be do that not stability cpu usages? I tried overclock 5ghz cpu but it didnt change anything. When I put vsync on and use framecap it looks like pictures but when I close vsync and none cap that all doing same thing. I really dont understand.Please look pictures picture , picture2
