Hello, here I am once more with additional queries. I finally got my i7 8700K running at 5GHz. Stress tests I ran included CPU-Z Stress Test and Cinebench R23 for ten minutes; Prime95 spiked to 100C and shut down immediately even on default settings. During the test, temperatures reached 81-85°C during continuous use, which isn’t ideal but not extremely bad. Could you assist in assessing whether these voltage levels and temperatures are safe? Key specs to consider: i7 8700K (unchanged), MSI Z370M GAMING PRO AC H100i RGB PRO XT 240mm AIO RM850 PSU (2019), BIOS settings with CPU Ratio, Turbo Ratio set to 50%, Enchanced Turbo enabled, SpeedStep active, EIST on, Turbo Boost on, C-states off, AVX disabled, RAM overclocked to 3733 MHz for stability. DRAM voltage at 1.35V, CPU VCCA at 1.150V, VCCIO at 1.100V. Thanks in advance.

It should hold up for roughly a year or two before minor issues start, after which stability will drop. As long as you meet its requirements and keep it under 85%, it should function well. Just watch out for Windows updates that might brick it. A score of 1.375 is slightly worse than usual, but it's still manageable if it runs smoothly. The 240 might struggle with heavy Prime95 tests, though that’s not a typical scenario.

Should Windows updates cause a brick? On Arch Linux, it only works with benchmarks.

Oh wow, you're a Linux user... I've seen Windows updates cause a lot of bricking on overclocked systems. RAM overclock tends to be the biggest problem when updating, but CPU overclock can also lead to crashes during updates, sometimes even bricking the whole OS.

They function independently with distinct motherboard settings and algorithms. MCE can sometimes cause unexpected power or voltage behavior based on board or BIOS updates. I’d reset everything without MCE to keep your allcore configuration intact, since it might need more voltage than the standard allcore setup requires.

Unknown if 1.376V is safe without more context.

It's a bit of an idle voltage situation, right? As a load voltage maybe for a short time. (Who knows how long...) Shouldn't we just stick to 1.30-1.35V if we're concerned? A 100Mhz and solid voltage drop won't really impact your performance much, especially if you're mainly GPU-dependent.

You can take the delid tool if you send it back. Before delid it was 1.35v, after it dropped to 1.31v with a 5ghz processor and a max temperature of 100c. Post-delid it reached 67c max.
