First attempt at 8700k overclock
First attempt at 8700k overclock
Sure thing! Here’s a revised version of your text:
Hey everyone, I’m about to give overclocking a shot myself. My rig runs an 8700k, doesn’t have a delid chip, uses an ASUS Z370-E motherboard, and has a Corsair H150i PRO RGB setup—push/pull mode, included fans, plus three LL120s. I’ve worked with systems before, but this is my first time doing it myself, so I’m comfortable with the specs and terminology.
I started with the ASUS 5G OC profile built into the board—it didn’t perform well, pushing voltages up to 1.4-1.5 volts. After resetting the BIOS, I rebuilt everything from scratch using my own settings. I set the ratio to 50, targeted 5.0 GHz, enabled XMP, and adjusted the voltage manually to 1.30. The multi-core boost was also activated. At 1.28, the system crashed immediately on boot, but at 1.30 it’s been running smoothly for a while now.
I’m using AIDA64 and ran CPU stress tests only. I kept temperatures between 68-70°C, with the hottest core reaching about 77°C. The CPU maxed out at 74°C.
Here are my questions:
1. When stress testing, should I mark additional boxes? In real life I mostly play games, but I do some homework too. My idea is that the FPU test matters mainly for those using AVX instructions, right?
2. Are there other BIOS settings I should tweak to boost performance? Should multi-core enhancement be enabled, for example?
3. Should I try pushing the clock speeds up to 5.1 or 5.2? I know it won’t really help in everyday use, but jumping from 4.7 to 5.0 didn’t make much difference either. Would it be worth going the extra mile?
Any other details you’d like to share would be great! By the way, my case is H700i—there’s a fourth LL120 at the rear exhaust, plus a stock NZXT 120mm fan on top, and two 120mm HD RGB fans at the front. The H150i is at the front as an intake, with push/pull mode.
Well if you're interested, I usually don't spend much time on any CPU since it doesn't really help much for me. My older CPUs aren't great because they're outdated. The newer ones seem to perform well at around 5.0 or 4.5. That means lower voltage, less heat, and quieter operation—especially when it's running at over 90% most of the time.
we share the same motherboard and processor, but mine handles 5.0ghz at 1.28v and 5.1ghz at 1.35v. currently i’m running it at 4.8ghz and 1.2v because the extra heat and noise aren’t worth the minimal gains. in gaming i’m completely GPU-bound (1080ti/1440p/high refresh), so i’ll keep the performance drop for a few years if needed. in the BIOS there are a few options—like boosting max current distribution to 140% (this matters)—but i don’t remember the rest. overall, stick with 4.8ghz and see what voltage you can safely use until the CPU ages.
Is the FPU test still necessary? Also, I'm seeing BSOD during stress testing for FPU and wondering if higher voltage would help.
When I apply stress to the FPU or run prime95, I encounter BSODs. This suggests a potential issue with power supply or voltage requirements. It might indicate a need for higher voltage if that’s the case. The mention of running at 4.8 hints at adjusting the operating parameters.
Essentially the same setup here. I can achieve 5GHz at 1.27v, 5.1GHz at 1.3v, plus 4.8GHz around 1.2v for lower heat and noise. i7 8700K with ASUS Z370-G Wi-Fi AC.
Returned to the setup, applied the 5G profile so the operating condition matched, adjusted internal power controls, and lowered the voltage to 1.33. I'm experiencing peak temperatures around 90°C, but AIDA isn't showing any throttling. I'll test further adjustments like 1.32 to determine the optimal setting. It seems the current value was the limiting factor, not the voltage.
I believe I've reached the end here. The 4.9GHz option works at around 1.30 volts, but 5.0GHz demands a much higher 1.4V or more. That 1.3V 4.9GHz clock reaches a maximum temperature of 78°C on the CPU, including FPU strain. Going up to 5GHz pushes it into unsafe territory and causes it to fail at 94°C. I’d skip 5GHz—probably the optimal setting is 4.9, which seems sufficient. It feels like a bit of luck with the chips.
