You're performing well within the limits. Boost clocks aren't necessary unless you're experiencing thermal throttling. At 80°C or less, you won't see any advantage from restricting boost clocks, especially if it's not a stock or lightly overclocked setup. However, at 90°C with less than 1.4V per core, limiting boost clocks could be beneficial. Just keep an eye on temperatures and adjust accordingly.
Around 82°C was the max I reached during Cinebench, with 77°C being the highest I've recorded while gaming. I've noticed some advice about adjusting the pbo curve, but when I applied -5 and -10 temps, they increased instead of decreasing as the CPU boosted higher—not quite what I hoped for.
80C works just fine and you rarely encounter 4550MHz consistently. Adjust your Curve Optimizer between -15 and -20 (or extend to -30 for stability) in the BIOS, which should significantly lower the temperature. This comes at the expense of stability, so you'll need to test a few settings to find the most stable offset. For me, setting it to -23 reduces the temperature by roughly 10°C.
No negative offset was applied. It doesn't make sense for temperature to rise.
I opted for the negative approach, testing both BIOS and Windows settings. I was hesitant to repeat this without understanding the issue.
