6600K to 44000Mhz with Auto Voltage (with images)
Hi,
I'm just starting out with overclocking and have reached 4400Mhz using the default stock voltages. By adjusting the multiplier, I've managed to lower the Vcore to 1.184V during testing. I haven't changed any jumper settings on my Z170-A. I've run Prime95 v26.6 Small FFT's and Blend for over an hour, and everything is functioning well. Temperatures remain low, under 60°C. Everything looks great but seems impressive. I was hoping for errors at this stage and would have to either lower the multiplier or raise the voltage. I'm hesitant about pushing it further to 4500Mhz. I've attached some screenshots (one during, one after testing). Currently, the system is running on Auto mode since it hasn't exceeded 1.3V. Should I try going to 4500Mhz??

Thanks for your reply's
Well, boosting the clock speed doesn't harm the CPU, but raising the voltage does, though it only becomes noticeable at very high levels. I believe you should push it as far as possible (around 1.5V is a safe upper limit). Also, you're really lucky with your CPU; mine only reaches about 4.1GHz at 1.4V.
No one is back:
Increasing the clock speed doesn't harm the CPU, but raising the voltage does, only noticeable at extreme levels. I believe you should push it to the maximum you can (1.5V is roughly safe). Also, you were really lucky with your CPU—mine barely reaches 4.1GHz at 1.4V.
Thanks. Since the voltages are so low, I thought I might not be using the monitoring software correctly or reading it wrong. I needed some confirmation and explained why I shared screenshots. I plan to try 4500, test longer, then stop. I enjoy tech, but I don’t like the 'pita' factor. My chip was purchased secondhand, from a BNIB RMA. Someone waited for the return and bought a new one (sold the old one). I got some savings and it looks like a decent chip. Maybe Intel is keeping the best ones reserved.

Congrats on winning the lottery!

You're in good hands. Please keep us posted on your journey. For the 4.5 boost, instead of a big jump in CPU voltage, maybe a tiny plus offset would help. Thanks for the encouraging votes from both of you. I’ve noticed a little issue — I think it might be worth checking how far it goes. Even if I don’t need it, I’ll try it. I was hoping for an automatic setting but ended up switching to manual. When it crashes, I’ll switch off auto, apply the offset, and save my previous voltage reading as a reference. It seems the Asus Z170-A doesn’t set auto voltage as high as others claim (BIOS updated). Appreciate your patience.
I received an update here. I reached version 4.7, still using auto voltage, without any problems. With RealBench, the Vcore remains steady at 1.264V under load, reaching 1.312V briefly when starting applications, etc. My peak voltage is well below what most manual readings show for others, so I consider this a success and won’t disable auto. It drops to 0.896V and 800Mhz during idle.
While still fine, I’m noticing the limits of the 212 EVO. At around 65°C in RealBench on some cores (21C ambient), it’s not even summer yet. It’s a minor issue but I can now hear the CPU fan slightly increase to about 100rpm when opening basic apps because of the extra voltage. This makes me think about upgrading to a quieter fan, though I’m okay with a steady hum—not a loud one. The fan control doesn’t offer enough adjustment to eliminate this variation.
I’m uncertain about moving to 4.8 since I doubt it would be practical for daily use or gaming. I’m sure it could work eventually, perhaps in a few years when needed. Thanks again.
A minor adjustment helped, as it maintained a 3.5 or 4.7 performance level. Changing to Adaptive Vcore versus Auto, with zero offset and power-saving activated, resolved the issue. The system was configured to 'balanced' power plan.
I tried 4.8 thinking it might be too high for my cooling system, but it actually works fine on auto voltage when starting under load (Windows enabled). Without adding extra voltage, I’m satisfied with 4.7. That was the only issue I faced during the whole process. Just wanted to close the thread and say I tried it. Thanks to the community for the help!
