i7 8086k reaches 4.7ghz during testing after being overclocked to 5.2ghz
i7 8086k reaches 4.7ghz during testing when overclocked to 5.2ghz. Why does this happen? When idle it maintains around 5200mhz, but under multicore tests it drops back to 4700mhz. Single-core runs stay steady at 5200mhz. It never behaved that way before—it stayed flat when running at 5400mhz the first time I had it. After a BIOS update and a CMOS reset, it can't return to stable 5400mhz. The main problem now is this instability at higher speeds. I need my full 5200mhz performance on a Z370 M Pro4 board with an ICE cooling setup (280mm front, 140mm rear, CPU and memory blocks in a tiny H17). Temperatures are around 50°C during Cinebench tests. GSKill Trident Z 4266MHz runs at 4133MHz (around 4133Hz), while my system is at 500GB NVMe SSD with WD Black 12GB. Any suggestions or help would be appreciated!
That’s how it’s configured, right? The minimum cache ratio is indeed set to 52. The 4300MHz comes from somewhere else, I’m not sure what.
The note indicates the second screen shot setting uses auto mode, which will apply a default of 4.7GHz across all cores. The cache operates independently from CPU core overclocking, so avoid adjusting it now.
You may need to adjust your long and short turbo settings carefully. The Auto option can be confusing—use HWiNFO64 to check why throttling happens. Power limit restrictions are typical. Make sure the AVX Ratio Offset is at zero. Both turbo limits were set very high, so they won’t block peak performance.
You probably handled those tasks before, but you mentioned seeing numbers like 120 and 150—maybe the best you got was 150. It seems like the top one was around there. You might have used AVX around version 3, and it’s been a while since you worked with it that way. Feels like you’re starting over now.
