Hey everyone. I'm a bit confused at what's going on with my 13600KF. I'm not new to overclocking but I've not kept up to date on everything that's changed in the last few generations of Intel CPUs (previous 2 CPUs were Ryzen). So at stock, the behaviour is awful. Even gaming sends the CPU temperatures to 100 degrees plus, this is despite having an Arctic Liquid II 320 cooler. Obviously, this is shit. So I went into BIOS and set a fixed voltage of 1.2v and left literally everything else alone. Now temperatures in gaming peak at 65-70 degrees depending on room temperature, and even in stress testing it peaks at around 80 on most cores. This is amazing, but obviously there's a lot of headroom there. So I did a mild overclock to 5.2 on all p-cores and 4.3 on all e-cores. Temperatures barely changed so I thought could push further. No dice. The CPU simply is not stable no matter what I do from this point. I can't even get 5.3GHz to successfully complete a cinebench render even if I set the vcore to 1.4v, which I wouldn't want to run it at 24/7 anyway. So I'm thinking vcore must not be the limiting factor here. However, no matter what I change, I do not seem to make any headway. I've followed guides, or tried to, but most of them recommending using offset vcore, which I've tried, but my motherboard only allows me to set an offset of -100mv, which has the temperatures way up past 100 degrees again. Also, at one point I updated my BIOS to achieve a higher RAM overclock (this is still stable, I've tested), and then the tjmax on my CPU went from 100 degrees to 115. I'm assuming that's safe but I don't trust motherboard vendors so much. The other thing is that whenever I change anything related to the vcore, my BIOS automatically changes LLC to level 1, which again I'm not super comfortable with for long term health of the CPU. Is that safe on ASROCK boards? Specs: 13600KF all core 5.2/4.3 at 1.21v ASROCK Z790PG Lightning 32GB DDR5 @ 6000MHz Corsair RM850 Gold RTX 3080 10GB
Basically, just lower the voltage a bit and if you want a gentle boost, modern chips are already close to their performance ceiling. You can try pushing it a little more, but only if temperatures stay manageable, the board is solid, the CPU voltage works well, and the chips themselves are in good shape. In many cases, the silicon quality might be the main bottleneck if you've missed out on it. Going overclock much further will only give a tiny performance gain, and the gains will shrink as you increase the speed, while heat will rise sharply because of resistance and other factors.
I wouldn't assume that. Intel determines the standard thermal throttling temperature at 100°C for a specific reason. They've explicitly stated they can't ensure long-term stability when you run your CPU above 100°C. Return this to the default setting.
