I3 8350K Overclocking Support
Are you running an LLC? It’s unclear if Coffee/Kaby Lake supports it, but using a lower Vcore with the highest LLC might yield better results. LLC isn’t advised at very high Vcore levels since it can increase Vcore under load if set to enthusiast. If you haven’t configured LLC properly, the drop in Vcore could cause instability. From what I understand, Coffee Lake/Kaby Lake tend to run hot, so a delidding is often needed for extreme overclocks (>4.8Ghz). As clocks get closer to extreme speeds, other voltages or settings usually need adjustment to keep things stable. Your cooler seems capable, but you might want to re-seat it and ensure the thermal paste is applied correctly—temperatures around 90°C at 1.52V are normal.
You're asking about using LLC with your system. It seems you're considering lower Vcore and higher LLC settings, but there are concerns about stability at high temperatures. De-lidding might be needed for extreme overclocks. Your cooler appears to handle the heat, but thermal paste application is important. The 90°C at 1.52V is within normal ranges. You mentioned trying LLC successfully at 4.8Ghz but still faced instability. It's possible a delid would help, or you might need to upgrade your components.
