Intel 8086K OC settings
Intel 8086K OC settings
Hey there,
I’ve been assembling my PC about a year ago! I started from scratch when it came to overclocking and spent a lot of time reading guides and tutorials. Now I’m reaching a stage where progress feels limited. My main concern is whether pushing the chip to its absolute limit will yield better results than exploring other possibilities.
Looking at my setup, my voltages seem quite high given the multiplier settings.
Here are my specifications:
- Case: Fractal Nano S
- Motherboard: Asus Strix Z370-I (mITX)
- CPU: Intel i7 8086K (delidded, copper IHS)
- GPU: EVGA GTX 1080ti SC2
- RAM: 32 GB G.Skill Trident Z 3200Mhz
- Power Supply: Silverstone Strider 850 Watt Platinum
- Cooling: Loop cooling for CPU and GPU (1x 240 / 1x 280)
My overclocking profiles are:
- BCLK: 100,000
- MuliCoreEnhancement: Disabled
- SVID Behavior: Auto
- AVX Offset: 0
- CPU Core Ratio: All cores synchronized = 52
- CPU Core/Cache Current Limit Max.: 255.50
- DRAM Frequency: 3500 Mhz
- Power-saving & Performance mode: Performance mode
- LLC: Level 6
- CPU Current capability: 140%
- VRM Spread spectrum: Disabled
- CPU Power Duty Control: T-Probe
- Speedstep: Disabled
- Intel Turbomode: Enabled
- HyperThreading: Enabled
- CPU C-States: Disabled
- Long Duration Package Power Limit: 4095
- Package Power Time Windows: 127
- Short Duration Package Power Limit: 4095
Performance metrics:
- Idle: Avg. 35
- Gaming: Avg. 60
- Torture Test: Avg. 74 (Aida64 Extreme)
I’d appreciate any advice to boost both performance and stability. Thanks a lot!
Your settings look excellent...5.2GHz at 74 degrees max on AIDA...I haven't found anything better, as I'm certain you've tested nearly everything to bring the vcore down for a stable 5.2 without any offset!!!!...I'm using a Gigabyte Z370 Gaming 7 motherboard, which affects how my BIOS operates. I tried the adaptive/offset method and can hit 5GHz at 1.345v, but beyond that I'm not comfortable with the required vcore, so I settle for 4.9GHz at 1.308v most of the time, keeping the LLC setting high. Also just delidded...it wasn't as scary as I expected, and the temperatures are now great...I couldn't imagine how much better it would be!...Hopefully others can help...but your overclock is impressive in its own way!
Only the top 14% of chips can achieve 100mhz faster regardless of settings.
Why is speedstep off? It’s just using extra power and stressing the CPU unnecessarily. If your clock stability is solid, it should be enabled. Otherwise, reduce the setting slightly.
What CPU did you have before? The 8086k model has been available for about three months, not a full year.
@vMax appreciates your feedback! I was just considering that the vCore might appear quite high when compared to other results I've encountered. However, my temperatures are actually quite good. The 74 Average values are derived from a four-hour test in Aida64, with everything running alongside the GPU.

Until yesterday, I believed my OC would perform flawlessly. As mentioned, it successfully finished a four-hour AIDA64 session.
But yesterday I experienced an unexpected BSOD while playing Far Cry 5 :/
And you're correct—I can turn speedstep back on again. However, I've heard that disabling it might be a better option when using manual voltage settings (not adaptive).
Before acquiring the 8700k, I really wanted to pursue OC but ended up with a disappointing result, so I switched to an 8086K.
EDIT: I've already tried 5.3 GHz. I managed to run Windows and completed a 3D Mark Fire Strike test, though it seems unsuitable for continuous use. I think I'd need to push beyond 1.45v.
Best regards,
