Thank you for your message. I've reviewed the post and confirmed that boosting the core voltage to 1.376 is within acceptable limits. It's important to check whether the number you entered matches the one displayed at the system stalled point. Regarding the multiplier, it seems you adjusted it to 46x. Currently, I'm using 4.5ghz with the same voltage. The system has run for about three hours without issues using AIDA64, though in-game stability is uncertain.
The normal behavior here is due to load line calibration. It's advisable to set a fixed level rather than relying on auto-adjustment. A higher LLC setting will provide more voltage to counteract voltage drop. It appears both your 6700k and mine are from the same batch, but mine is a bit lower in voltage and may not overclock as effectively at lower voltages because of silicon variation.
Feel free to adjust your settings accordingly.
@Skidushe, my 4.5ghz seems stable at 1.345. I’m still testing 4.6ghz with a 1.36v setting, but it’s still running around 1.38v. The temperatures are quite similar to what I’ve seen before. Also, I’m not using CPU-Z or HWMonitor much anymore because they don’t seem reliable. Right now I’m using AIDA64 trial version; I might stick with it unless a better tool appears. My motherboard is Asus, and the AI suite gives readings that match AIDA64. The CPU-Z and HWmonitor aren’t very accurate either. Someone told me these apps only show the voltage the CPU requests, not the actual supply voltage. I’ve also been told manually setting it is preferable to adaptive mode.
Thanks for your response. I have mine set at level 6, should I lower it to level 4 instead?
You can try it and check if the voltage changes and stability are okay.
From a temperature perspective, everything seems fine as long as it stays below 80°C. Just keep in mind it might differ by +/-5°C from the actual reading.
There isn’t a perfect tool besides a multimeter. I think AI suite is a bit slow to respond and can lag; I prefer HWInfo over HWmonitor or AI suite. Cpu-z displays either vcore or VID based on your BIOS settings. If SVID is enabled, it usually shows VID instead of vcore. You’re looking for vcore.
Most instructions suggest using manual mode to test at a steady voltage. Adaptive mode can still work but will vary with load and stress type.
AIDA64 is quite straightforward for stress testing, using X264 or Asus Realbench would be my advice. Just remember realbench also puts pressure on the GPU.
I understand, I'm testing both AIDA64 and RealBench right now. I'm currently using AIDA64 for my temperature settings. Unfortunately, the configuration of 4.6 at 1.36v didn't stabilize. So I'm lowering it to 4.4GHz, but it still doesn't work at 1.35v after this latest test. I'm worried about missing out on a stable result and hope to keep you updated if I manage to maintain stability at 4.4GHz with 1.35v. This situation is really frustrating, especially since I didn't realize how much it could impact my progress.
LOL Yes sir, it can really be annoying. The worst part for me is I built a rig about two weeks ago and the board died. It was a cheap gigabyte one. I’ll never chase another such product again. But I probably didn’t have a problem with my CPU—it ran at 4.5 with a 1.26 vcore, but I didn’t want to risk it, so I sent it back with the board to Frys and got a new one. This one is a bit more powerful. Always trust what your CPU tells you. What’s set in your BIOS and what the actual readings show can differ a lot, but you should always keep an eye on them. I don’t know about you, but I’m not letting a 1.4 vcore scare me anymore. I’m confident that with liquid cooling, your chip won’t get hotter than 65°C at 1.4 and it won’t shorten its lifespan. It’s just $300. That’s a joke. Remember this: chip wear is rare, especially nowadays. And just because it’s a CD doesn’t mean overclocking will ruin stability at 4.0 GHz. If you ever think about giving up, I’ll keep it stock to avoid feeding it a 1.38-1.4 vcore. Just stick with the 1.4 now and enjoy—guaranteed your chip won’t become unstable at 4.0 GHz. If in the future you need to lower it to 4.5 at 1.4, it’ll take a long time if your temps are good. And it will never cause instability at stock speeds with a vcore under 1.4. If you have to drop it to 4.5 at 1.4 later, it’ll be a long wait if your temperatures stay low. Never let it happen stock at 1.4—find your ideal balance and stick with it because if you’re okay with running it stock now, at least create some wear before going back down. Got it?
I believe my 4.5ghz remains stable at 1.345. I’m still testing 4.6ghz with a voltage of 1.36 but it’s still holding steady around 1.38v during tests. The temperatures are quite similar to what I’ve seen before. I’ve also shared earlier that my readings are consistent. I currently use AIDA64 trial, which seems reliable enough unless I find another tool that gives more precise data. My motherboard is Asus, and the AI suite gives similar results. CPU-Z and HWMonitor aren’t very accurate for me anymore. Someone told me these apps only show the voltage the CPU requests, not the actual supply voltage. They suggest going manual instead of adaptive. Just keep reading the values as they change; if it stays within a small range like 0.001, it should be fine. For example, my current core voltage is 1.34, which is very close to the 1.345 set in BIOS. If you want better accuracy, a multimeter would be ideal.
Rain2o : LOL yeah, it can be really annoying. The worst part for me was when I built a board about two weeks ago and the board died. It was a cheap gigabyte one. I’ll never buy another gigabyte again after that. But I probably didn’t have a problem with my CPU—it ran at 4.5 with a 1.26 vcore, and I didn’t want to risk it. So I sent it back with the board to Frys, got a new one, and this one is a bit more powerful. Still, always trust what your CPU reports. The numbers in your BIOS and actual readings can differ a lot, but you should listen to what the CPU says. Honestly, I’m not letting a 1.4 vcore scare me anymore. I’m confident that with liquid cooling, your chip won’t get hotter than 65°C at 1.4, and it won’t shorten its life. It’s just $300. Don’t take it too seriously. This is what you need to remember: chip wear isn’t normal, especially nowadays. Just keep in mind that extra heat from CDs only means more voltage is needed to stay stable at a certain speed. If you start thinking about giving up, I’ll keep it at stock so you don’t overload it with 1.38 or 1.4. Just run it at 1.4 now and enjoy—guaranteed your chip won’t become unstable at 4.0 GHz. If ever you find yourself in a situation where stability drops at stock speeds with under 1.4, I’ll buy you a new chip. That’s my take on it. Worst case? If it ever happens, it won’t be enough to ruin your chip’s performance. If you have to lower it later, it’ll be a long time if your temps are good. And it will never make your chip unstable at 1.4. Just find your ideal balance and stick with it. That’s the plan."
Absolutely. I understand there might be some minor wear, but I’m confident it won’t significantly reduce the lifespan of your chip. I genuinely think maintaining a consistent 1.45 even if it stays at that level indefinitely will ensure your mobile remains stable and functional, allowing it to revert to default settings without interruption. I won’t need to revert back to Frys or buy another 6700k because I’ve already set it up correctly.
Rain2o shared his thoughts on a frustrating experience. He built a new motherboard about two weeks ago and ended up damaging the chip. He mentioned he was using a low-end Gigabyte board and didn’t want to risk another purchase. Despite thinking his CPU might be fine, he took it back to Frys for a replacement, which turned out better. He emphasized trusting the CPU-Z readings over BIOS settings, noting that real-world performance often differs from what the BIOS claims. He reassured others not to worry about a 1.4 vcore, stating his liquid cooling setup would keep temperatures under control and that short-term stability at stock speeds is unlikely. He also warned against lowering the voltage too much, suggesting a balance between performance and thermal safety. Finally, he asked for advice on safe operating temperatures with close-loop liquid cooling and thermal paste application.
Here’s a rewritten version of the text with the same length and structure:
The situation is definitely annoying. The worst part for me was creating a board about two weeks ago and damaging the motherboard. It was a cheap gigabyte board. I’ll never buy another one after that. Still, I probably had a stable CPU running at 4.5 with a 1.26 vcore, but I didn’t want to risk it. So I sent it back with the board to Frys and got a new one, which is a bit more powerful. Of course, always trust what the CPU-Z shows. The settings in your BIOS and actual performance can differ a lot, but you should always keep an eye on the readings. I don’t know about you, but I’m not letting a 1.4 vcore scare me anymore. I’m confident that liquid cooling will keep my chip under 65°C at that voltage, and it won’t shorten its lifespan. It’s just $300. Don’t take it too seriously. This is what I want to remember: chip wear is rare, especially nowadays. Sometimes it comes down to how much heat you generate during regular use. If you’re thinking about giving up, I’ll stick with stock unless you’re sure it won’t handle 1.38-1.4. Just keep it at stock now and enjoy the performance because I promise your chip will stay stable at 4.0 GHz. If ever you need a new one, I’ll buy you one—especially if you push it to 4.7 and then have to lower it back to 4.5 at 1.4. That would be a long time if your temperatures are good. And definitely not cause instability at stock speeds with under 1.4 vcore. If you ever find yourself in a tough spot, I’ll replace the chip. That’s my take.
Thanks for the advice.
Anyway, I’m settling for 4.4 GHz and keeping the voltage at 1.376. Running realbench for four hours shows temps around the high 60s. Maybe I should reapply some thermal paste or that’s normal?
What’s a safe temperature range with that setting, especially with liquid cooling H100i v2?
Thanks again!
