The i7-7700k may operate at elevated voltages and temperatures.
Hi,
I just increased my i7-7700k to 4.6GHz with MSI Game Boost. When I looked at the voltages in Command Centre, they seemed too high for that frequency, which might explain why my CPU was running at about 80-85°C during the ADIA 64 stress test and around 40-50°C when idle. Do these readings make sense? I’m aware the chip is quite hot, and I have the MSI Z270 MPOWER TITANIUM board.
Thanks.
Very low voltage levels detected. The 4.6Ghz frequency is just 100Mhz above the standard boost frequency. The CPU remains suitable for regular use up to approximately 1.3 volts. Higher performance is possible with better cooling solutions or after removing the lid. Operating temperatures between 80-85°C under AIDA are acceptable.
The reading of your link seems correct. You can track vcore with cpu-Z. Keep it below 1.4v. Your ability to overclock depends largely on the quality of the chip you choose. Here are some figures:
As of 6/9/17
Percentage likely to achieve an overclock at a reasonable 1.4v Vcore:
- I7-7700K: 4.9 83%
- I7-7700K 5.0: 62%
- I7-7700K 5.1: 29%
- I7-7700K 5.2: 6%
Temperatures are mainly influenced by vcore. Your stress test at 80-85°C should be accurate.
The part that might cause issues is your 40-50°C during idle. A good cooler should keep it within 10-15°C above ambient.
What cooler are you using?
Does your case provide enough fresh air for the cooler to function properly?
Is a high-end graphics card installed?
I think adjusting the BIOS settings directly could help you improve performance.
Think about removing the case. When I received my 7700k, the best overclock I achieved was 4.8ghz at 1.28v, with temperatures around the 90s. After doing the delidding, my peak overclock reached 5.1ghz at 1.385v, and the max temperature stayed in the high 80s. Currently, I run 5ghz at 1.345v, with temps ranging from the high 70s to 80s.

I understand that doing a delid can be intimidating and might void your warranty, but I think it’s worth trying. Der8auer's Delid Die Mate 2 is a good choice. If you’re unfamiliar with Der8auer, you might want to look them up. The delid process is quite straightforward. I also suggest using Thermal Grizzle Conductonaut liquid metal for better cooling.
After fine-tuning my CPU overclock, I decided to push my RAM up from 3000mhz to 3200mhz—this was a different story altogether.
An overclock can be restricted by temperature or by the voltage you decide to use.
In nialbu91’s case, exceeding 1.28v at 4.8v showed more potential from the voltage side.
It seems the chip likely lacked a proper heat sink.
Removing the package was a sensible decision if the extra 0.2v mattered.
I believe the gap between 4.8 and 5.0 won’t be noticeable in games or apps.
But if you plan to delid, a professional service might be more suitable.
The drawback is losing the CPU temporarily.
