Under full stress at 100%, the performance remains satisfactory.
Hi, I was curious about whether the 7700k would actually handle such high temperatures or if my cooler installation might be the issue. At just 1.264v according to CPU-Z, I see these temps: /imgur.com/a/5JqNs. Your readings seem normal. I tend to adjust the BIOS fan curves around 80°C and reduce overclocking if it approaches 90°C. But Prime95 is no longer commonly used for OC stability checks; AIDA64 Extreme's System Stability Test is now more popular.
Yes, it seems anything priced below 80c is suitable for continuous use, though my low voltage setup and strong AIO might make that seem expensive. Are you wondering if AIDA is using more CPU power than Prime95? If so, my temperatures are likely too high.
Thanks yes, I understand that anything under 80c should be suitable for continuous use, but given my low voltage and what seems like an impressive AIO, this might be a bit too much. Is AIDA pushing the CPU more than Prime95? If so, my temperatures are definitely off.
1) It's possible your CPU isn't receiving clean power. Could you tell me the make and model of your motherboard and power supply?
2) Prime95 actually forces the cores harder than AIDA64 does, but it doesn’t stress other CPU components as much. AIDA64 lets you stress system memory (RAM), which puts extra load on the memory controller inside the CPU. This can help reveal instability that Prime95 might not show. In short, Prime95 will push the CPU 2-3C higher than AIDA64, but AIDA64 may uncover more potential issues in your overclocking.

Thanks yes I understand that anything under 80c should be suitable for continuous use, but given my low voltage setup and what appears to be an excellent AIO this seems a bit steep. Is AIDA pushing the CPU more intensely than Prime95? If so, my temperatures are definitely off.
1) It's conceivable your CPU isn't receiving clean power. Could you share the motherboard model and power supply details?
2) Prime95 really pushes the cores harder than AIDA64 does, but it doesn't stress other CPU components as much. AIDA64 offers an option to stress system memory (RAM), which can overload the memory controller inside the CPU and let you test the FPUs together or separately from the cores. Stressing system memory, FPUs, cache and CPU will really challenge the schedulers and decoders, possibly revealing instabilities that Prime95 wouldn't encounter.
In short, Prime95 will push your CPU 2-3C higher than AIDA64, but AIDA64 might show more potential instability in your overclocking process. Thanks for the help, I have the Asus PRIME Z270-A motherboard with 8+2+2 phases and then a Thermaltake Toughpower XT 775W PSU, so I feel confident on the power side.

I agree the VRMs are robust, but paired with those thin aluminum heatsinks. It was nice to get an AiO with a fan for airflow around the socket; otherwise you might have faced problems.
It seems you've had some luck issues with the chips. Your CPU overclocks well, though not exceptionally.
It seems we'll likely need to desolder the CPU in the future, aside from that. We're all aware that Kaby Lake comes from a complacent Intel, but I only realized this after searching online that they were so proud of their efficiency they chose lower quality TIMs.

Looks like we might need to remove the CPU in the future, nothing else seems necessary haha. We're all aware that Kaby Lake comes from a complacent Intel, but I only realized it after searching online that they were so proud of their efficiency they decided to use lower quality TIM.

It's really a shame they went for such a cheap option. If I were to do a delid, I'd probably be fine pushing this chip over 5ghz since it runs "stable" at 4.9 @ 1.26v and the max safe voltage is 1.4v according to most sources.
