Hi All I have actually just RMA'd my graphics card for this issue. The replacement I got has the same issue. I finally noticed that iCUE was crashing every time (i managed to get it into a reproducible state after weeks of testing) To reproduce it easily, first turn TDR off, this is the windows feature that recovers the graphics card. You'll notice that when it crashes everything just stops, usually for a few seconds, sometimes it dies completely. TdrLevel - Specifies the initial level of recovery. The default is to recover on timeout, which is represented by value 3. KeyPath : HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\GraphicsDrivers KeyValue : TdrLevel ValueType : REG_DWORD ValueData : 0 - Detection disabled OR 3 - Recover on timeout The test that I could run to get the issue to happen every time was BurnInTest set to CPU maximum heat, and cranked up to 100% CPU usage, whilst having iCUE running and HWiNFO64. Now when you open HWiNFO64 and go into sensors, it prompts me to monitor the ASUS motherboard setting or not, which I ignored for the time being and monitored everything. This would crash, instantly. Many many times, with a small 1-5 second gap then 1-5 seconds of crashing. I realised iCUE was crashing, so I googled, found this reddit post: Which led me here. Now, through further investigation and a lot of reading, I'm pretty confident saying that the issue is iCUE monitoring the ASUS EC, and then running a program like HWiINFO64 will trigger the crash instantly. Whilst after all my testing, I don't believe all these steps are required, they are the ones I took in the process. As per below I'm pretty sure you can force the crash quite easily. I don't believe it is iCUE's fault at all, but as it is an application which we need for all our corsair products to function correctly, many people have it running ALL the time. If for any reason another tool read's the ASUS EC at the same time as iCUE, it will kill the display driver.
