As Intel's new 7th generation processors roll out, PC users who like to tweak their system performance will continue testing and experimenting with just how far they can push them. Unfortunately, Intel thinks it is a bad idea.
The company has taken to its forums and asked that users refrain from overclocking the newest processors. It appears that the company was getting reports of high heat and temperature spikes on the i7 7700k SKUs, particularly when they were overclocked about 4.8 Ghz:
“The reported behavior of the 7th Generation Intel Core i7-7700K Processor, showing momentary temperature changes from the idle temperature, is normal while completing a task (like opening a browser or an application or a program).
In our internal investigation, we did not observe temperature variation outside of the expected behavior and recommended specifications. For processor specifications, please refer to the Intel Core i7-7700K Processor Product Specifications.
Most motherboard manufacturers offer customizable fan speed control settings that may allow for smoother transition of fan revolutions per minute (rpm). Please consult your motherboard manufacturer’s manual or website for instructions on how to change default fan speed control settings.
We do not recommend running outside the processor specifications, such as by exceeding processor frequency or voltage specifications, or removing of the integrated heat spreader (sometimes called ‘de-lidding’). These actions will void the processor warranty.”
Intel did replace an i7 7700 that Geeksultd was testing, saying it died within a week of overclocking. Intel didn't ask any questions before replacing the processor, but took to the forums with their response soon after.
