Inquiries regarding voltage and overclocking
Inquiries regarding voltage and overclocking
1.42v exceeds the limit at 4.7GHz but is acceptable at 5.0GHz. I recommend manually adjusting to 4.7GHz in BIOS and performing a stress test with ROG RealBench for stability. After that, lower the voltage until you reach an optimal setting. You shouldn't require more than the necessary CPU power unless you're running intensive tasks like workstations or servers. Avoid overheating by limiting the boost to 5-10%. Also, the H100i struggles with voltages above 1.300v.
Example with imaginary numbers:
4.7GHz OC @ 1.300v → passes → 1.275v → fails → 1.280v → passes → 1.285v (0.005v for extra stability). That's a significant change. If possible, maintain high pump speed and tweak the fan curve accordingly.
It seems like you're facing some issues with your cooling system after a stress test. The temperatures rose significantly, suggesting the cooler might be struggling under the load. You're considering whether the performance gains justify the cost of a better cooler. Regarding the 150i, it sounds like you're thinking about swapping parts to improve cooling, but you'd need to carefully disassemble and clean the current unit before installing the new one.
Zebarjadi.raouf shares his thoughts on the situation. The 1.42v setting is too high at 4.7GHz but normal at 5.0GHz. He suggests manually setting it to 4.7GHz in BIOS, then running a stress test with ROG RealBench for stability. He recommends lowering the voltage until you find an optimal balance, avoiding CPU power beyond that unless needed for demanding tasks. He also notes that the H100i struggles with voltages above 1.300v and provides an example of a test progression to help understand the process.
Ok cool. So I basically did the realbench stress test at 1.285 and it did freeze a bit when I was moving the mouse around and opening internet windows. I went down to 1.28 and it seems to be doing ok. I don't really understand voltage at all. Like..if it still says 4.7ghz overclock...what the heck is the point of the voltage? What does it actually accomplish?
Since this is a brand new build..do you think I should change out the cooler? Or is the difference between what im getting and what im going to be getting relatively minimal?

In no game I'm familiar with would 8700K cause issues at stock settings, let alone with an overclocked configuration. For improved performance, consider upgrading your GPU if necessary. 8700K works well with GTX 1070Ti/1080/1080Ti. If you already have it, you probably won't need anything more.
I chose a 1080i model for this recent upgrade because it helped me plan my changes. Upgrading parts can be tricky, but the previous build I had lasted about four to five years, which suggests it was reliable.
Cactusgod11 shared their experience using a 1080i display in a recent upgrade. They mention struggling to decide between component upgrades and a full rebuild, noting that the previous build lasted several years. They recommend focusing on improving the GPU for better performance. Suggestions include installing MSI Afterburner, adjusting power limits, increasing core clock gradually while monitoring benchmarks, and keeping temperatures under 80°C. They advise saving the profile and avoiding overclocking at startup unless necessary.
Zebarjadi.raouf shared his experience about using a 1080i display in a recent upgrade. He mentions he prefers building new systems rather than upgrading parts, but notes that the previous build lasted several years. He recommends focusing on upgrading the GPU next time and suggests following a specific guide for overclocking the 1080 Ti. He also advises keeping temperatures under 80°C and adjusting overclock settings if needed.
