So I have a bit of an odd issue. I recently upgraded to a 8700k and a 1080ti from a 6700 and and 1080. For some reason, it crashed constantly when gaming, with no overclocks on either the cpu or gpu. I had to set the core clock on the 8700k at 4.6 to keep it stable. It works fine, but here is where it gets weird. I pulled the 1080ti out, and put in the 1080, and like magic, i was able to OC the 8700k to 5 ghz without breaking a sweat. I plugged in the 1080ti to my 6700 cpu and mobo, and was able to overclock it as well and it was flawless. No crashes. I thought maybe it was not getting good power, or my psu was old or something. So i replaced it with a 1000w 80+ gold psu. Still have the same issue. I can do everything perfectly fine at 4.6ghz and the base clock on the 1080ti, but its like having a Ferrari but only being able to push the throttle half way down.
I did a clean windows install.
I followed the official Aorus OC guide. (aorus z370 gaming 7 mobo)
Upgraded psu.
Have a noctua dh-d15. About 75c under full load at 5.0ghz with the 1080. about 60c at 4.6.
Only thing i haven't done is tried different ram. It's cheap hynix ram, but not sure why that would make a difference seeing how it works like a champ with the 1080.
Edit: Noting as well that it crashes with running default bios settings.
Does anyone have any thoughts? I am at a loss.
