Question about CPU
Question about CPU
Hello, I've been struggling to achieve a stable OC around 4.2 ghz, but now I think 4.0 ghz works well with my i5 4690k at the moment. I set it to 4.0ghz with adaptive voltage, but is adaptive voltage actually harmful? I remember it increases voltage, reaching up to 1.279v at 4.0ghz in AIDA64, though temperatures stayed below 65°C. Should I still be concerned about this?
Also, how much of this extra voltage might affect the CPU's lifespan? Previously, CPU-Z showed a default voltage of 1.211v when everything ran at stock speeds. Now that I switched to adaptive, it stays at 1.211v during idle but jumps to 1.279v at full load with temperatures under 70°C. Should I still worry about longevity?
I just changed the multiplier to 40. The maximum CPU cache is set to "AUTO", and the CPU input voltage is also "AUTO" at 1.776v. The CPU core voltage is now "ADAPTIVE". For more details, you can check this link: https://gyazo.com/1d06845fe8e06a9bfd343da22e56fdca
I expected similar results, but with 1.3 v it struggles to maintain stable 4.4. The temperature stayed within normal range, though I never reached 85°C. Adjusting to 1.275v or slightly higher didn’t help, and using adaptive at 4.4 still caused BSODs. I doubt I’ll exceed 4.0 anytime soon, even after several years. This CPU remains solid at 4.0 compared to today’s standards.
I’m concerned about the adaptive voltage setting—does it work normally or should I switch to manual mode to lower the voltage? Since temperatures rarely hit 75°C, I feel confident it’s fine, but higher voltage might reduce lifespan even if temps are okay.
1.279v for just 4ghz? Something seems off or the chip might be faulty.
If you're facing major issues during OC, I'd recommend using manual voltage for testing and then proceed from there.
Begin with 1.250v and observe how much further you can push it.
My 4690k reaches 4.5ghz at 1.250v, but keep in mind each chip behaves differently.
It's about adaptive voltage to ensure stability, I believe lowering it a bit helps maintain balance. I'm not using full CPU load in games, so the CPU stays at 1.211V just like when it was at 3.8 turbo. I'm curious why CPU-Z shows 1.211V even at stock clock speed.

Notice the 1.211v Core Voltage, it fluctuates to 1.279v briefly before returning to 1.211v, with a maximum of 1.279v.
Also let me know what temperatures you're experiencing when stressing the CPU.

I've recorded these temps using AIDA64 and logged everything along with the stability test.

Have you considered increasing the LLC? It might stabilize voltage fluctuations, though it could also raise them.
I would adjust your CPU voltage manually, reverting back to standard voltages and clocks, and raise the LLC settings to ultra high or extreme levels. Once you reach a stable overclock that suits you, you can turn adaptive voltage back on and fine-tune it to align with the manual setting. Regarding cooling, my system uses a custom water loop with 360mm of radiative heat dissipation for both CPU and GPU, driven by a D5 pump.
