Ok my temperature findings as follows:
As it stands, on the 970, I was running 4.3GHz @ 1.12V and everything was great, temps maxed out at 95-96 degrees in sythetic loads where the CPU + GPU were both running at 100% in a worst case scenario very high ambient temperature environment with absolutely no airflow. When I put the FTW3 in and ran the same test, it crashed very quickly
Next I tried 4.2GHz @ 1.1V and it the test would run fine with no crashes, but the CPU was thermal throttling every 5-10 seconds or so. I tried to set the FTW3 fan speed at 100% (to see if forcing more air into the case helps) but it did nothing to alleviate the CPU temperatures and it continued to throttle. So I decided to work again on the CPU settings
I tried 4.1GHz @ 1.05V next. This brought temperatures down quite a bit, and I saw max spikes of 95 degrees (average 90 degrees) on the CPU with no throttling.
In all cases, the GPU was left at default settings with steady boost clock at 1900-1911MHz.
So my conclusion is:
If you want to run the 7700K stock, along with a 1080Ti in the case, and would like a very safe starting CPU setting which will work in even the worst possible situations at the highest reasonable ambient temps, go with 4.1GHz at 1.05V and work your way upwards depending on your ambient temperature, airflow, and how lucky you got with the silicon lottery
Hey I'm pretty new to OCing and wondering how difficult is it to adjust the CPU settings like this on the 7700k?
