Unusual voltage problems with the CPU...
Hey there, I'm still using that Intel Core i7-7700K. I was attempting to push it to 4.8GHz and adjusted the BIOS settings for CPU core/cache voltage manually at 1.30V. After booting, I noticed the voltage was limited to 1.232V. I ran stress tests and benchmarks, and everything worked smoothly without any crashes or overheating. When I changed the BIOS setting back to AUTO, the voltage could rise above 1.4V. My concern is whether this overclocking was successful or if there are issues with the motherboard or CPU itself.
The issue revolves around whether a 7700k overvoltage test will succeed and why you encountered that error initially but not consistently afterward. The motherboard model and BIOS version could help clarify this. Regarding overclocking, it’s important to note that OCs aren’t always reliable—this is why they’re used to push performance. Historically, gains were around 40%, but now they often drop to about 10% depending on luck.
My motherboard is ASUS PRIME Z270-A. BIOS 1302(the latest version). I've tested the CPU stock frequency then I got the same weird CPU voltage issue. Even on the stock frequency when Voltage is set to 'Manual' and whatever number you put, It max out at 1.21~1.23V. When it is set to 'Auto', it will still go above 1.4V. So I assume my motherboard has some issue with the VRM. Need to find a time to RMA it. Thanks for your help anyway.
