Hi all. I guess you have seen something like this and may lead me to a solution: a GPU switching off while gaming, yesterday this happened even on Desktop / almost idle. In addition sometimes since a few days the system hangs occasionally, on load, on idle, sometimes "when Jupiter is near Uranus" (without any notable reason). I played Shadow of the Tomb Raider => able to play for say half an hour or an hour, then *BLINK* and monitor goes dark. A look from above into my tower shows the red RD LED logo is off. Keys and mouse does NOT work, neither does my power button (!!!). The reset switch PARTIALLY works (haven't seen something like this anywhere), it kills the machine, reboots it but still the GPU is OFF (no LED, nothing) and finally I had to kill the machine by PSU switch (I know, the worst way, but nothing helped!). Going back to Desktop and looking into EVENTVIEWER and found something I think, besides the message Windows didn't shutdown properly (event 41) and some event related to "Kernel power" with "ID 172" I don't understand: Code: Verbindungsstatus im Standbymodus: Disconnected, Ursache: NIC compliance Connection status in standby mode: Disconnected, Reason: NIC compliance This happened 1 second after the "unsuccessful shutdown" message, it's the next event. In addition I have HUNDREDS of these messages: Code: Die Anwendung \Device\HarddiskVolume4\Program Files\AMD\CIM\BIN64\RadeonInstaller.exe mit der Prozess-ID 8568 hat das Entfernen oder Auswerfen für das Gerät PCI\VEN_1022&DEV_1453&SUBSYS_87471043&REV_00\3&11583659&0&09 beendet. The application (>>NAME<<) with process ID >>ID<< has finished removing of ejecting the device PCI\VEN_1022&DEV_1453&SUBSYS_87471043&REV_00\3&11583659&0&09 Before those they try to remove Code: ACPI\PNP0A08\0 , whatever this may be. The processes differ, but ranging from ASUSsuite and RadeonInstaller to SVCHOST.EXE or daemontools. Why the heck do those want to remove some PCI device? It seems to be a "PCI bridge". But they are THOUSANDS to try to remove the device. I got 2374 warnings in eventviewer, and about 2350 are from those! It's driving me nuts! And AMD's driver update mechanism seems to be somewhat broken, too. I installed the "old" 18.10 chipset drivers, followed by the 18.11.1 GPU drivers I had on my HDD still after reinstall of Win10 1809. The GPU driver told me "18.9.3" would be recommended. After saying OK install told me I would be "up2date" and didn't install any driver (therefore I went with 18.11.1 on second run). 18.11.1 then told me there was "a newer driver" 18.11.2 available (OK, download) and 18.11.2 recommended 18.9.3 again. So probably I am too "unused" to use AMD, so here a few questions regarding all this: - First: Because of these issues, should I return my card? It is still brand new and warranty would cover me completely. - Otherwise: What could be the issue here? - Then: What's with the drivers? I am running R7-1700 w/ 16GB DDR4-3200 @14-14-14-28-1T on an ASUS X370 Strix mobo with the Powercolor Vega 64 Red Devil as GPU. And in what order should I install? I learned "go from the center to the outer things" so mainboard/CPU first, then all what's plugged into the mainboard, then other things. - Why do these 18.9.x and 18.11.x driver branches exist? Is there a specific reason? I found both "valid" for my RX64, but why are there two? - My PSU is a Seasonic 850W 80+ Bronze, but no OC is done at all, so in theory and practice this should still work, right? The system was rock stable with my previous GTX970 (except the DP issue, but no "hang" at all). - I am not able to run ANY games continously if they are newer gens with better GFX. But at the same time I am able to run the newest Leisure Suit Larry and a lot of "older games". @OnnA / @Agent-A01 : OnnA, you have plenty of experience with AMD devices, probably you could help me out here? Agent-A01, I know you have an immense knowledge of hardware specs and stuff, probably it's related to something I didn't consider yet.
