I7 8086K OC
I7 8086K OC
Hi, my 8086K was successfully OC'd to [email protected]. I'm using a Noctua NH-U14S cooler, and temperatures stay under 70°C during gaming and above 84°C during stress tests with Prime 95 26.6. I'm curious if it's possible to push it higher without exceeding 70°C while gaming. Also, regarding silicon lottery, how does my chip compare to the average? I saw an i7 8700K running at [email protected]. Thanks for your help and feel free to share your OC results for both models.
There isn't a clear way to explain it, it depends entirely on how your processor handles the overclocking. All I can say is - the chance of losing a £400 CPU for just a few hundred megahertz isn't something I believe in.
Each chip is unique even though the 8086s are expected to generally perform better as overclockers compared to other chips. I wouldn't gamble on a chip like that unless I was aiming to set an OC record or something similar. Honestly, if I had such a chip, I wouldn't even consider running it for OC anymore—it should easily handle most tasks you'd throw at it. I'll also mention that my 9700k wasn't stable at 1.2v stock, which is just the silicon lottery, right?
Were they stable? Yes, I can easily achieve a 1.26 GHz with my 8700k at 5GHz, but performance drops under heavy AVX tasks unless an AVX offset is applied.
I discovered overclock results for our 8700k after a long weekend of stress testing. It looks like I can maintain stable performance at a Vcore of 1.34v for about 8 hours using Prime95 v26.6 in blend mode, and also pass 8 hours of stress testing on the real bench. Notably, Real Bench (which uses AVX) succeeded with all cores starting at 1.31V, but the 26.6 blend mode caused blue screens within the same 8-hour period when cores were under 1.34v.
What kind of stress testing was conducted? I evaluated the performance under 1.28V conditions, noting it might be insufficient for stable operation with AVX. It’s possible achieving stability without AVX is possible, but running intensive AVX workloads for over eight hours at that voltage would indicate a robust chip.
I don't intend to run 8 hours of stress testing. That's fine as long as it doesn't cause a crash during gaming.
