Intel Wants You to Stop Overclocking Your i7 7700 Processors

Aside from heat issues, it just voids the warranty.


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.

      yah I've seen this reported a few places.. I think a lot of this has to do with people throwing way too much voltage at the chip.

      Or using Auto-Overclocking features on motherboards which will generally use way too much voltage for small clockspeed gains.

      the i7-7700K was a bit different than Skylake or Haswell CPUs it uses a lot less voltage from what I've seen so you can't compare them directly.

        my 7700k is stable at 4.8ghz with only 1.25v, but anything over 4.8 no matter the voltage is unstable and goes well over 80c. but at 1.25v and 4.8ghz, it can get a toasty high 70's more often than it probably should, but it's very stable

          Yah that what I'm saying people are following Skylake guides that 1.24-1.28v is your default voltage for a stock CPU. For example my i7-6700K defaults to 1.26v and I can get up to 4.5ghz at default. I keep it clocked at 4.7ghz @ 1.34v and temps rarely get above 70C.

          Now with Skylake people are pushing upwards of 1.4v without significant issues for high clocks above 4.8Ghz. But for that you need serious cooling!! Hell I've seen some people pushing 1.45v on water with a delid and temps stay under 80C.

          With that new chip the voltages are a lot lower and I think the general rule was don't exceed 1.3v unless your water cooling or have excellent air cooler. Also I think the AVX thing where certain instructions can cause the CPU to jack up the voltage +0.1v higher for short periods!! So people doing something stupid like setting 1.4v suddenly their CPU hits 1.5v which isn't safe at all!!

          I can only get 4.6ghz @ 1.2v to stay under 80C
          To do 4.7 I have to go more than 1.22v and then I start hitting 85C+ in Prime95 SFFT tests.

            You need to use a AVX offset most likely see the anandtech link above

              What's something good to test temps with that doesn't use AVX then?

                I use RealBench -

                It uses real apps to bench/stress test your system.. be warned the stress test will max your CPU & GPU both to 100% at the same time!

                  Now we're talkin. 4.8ghz with a 15 minute test and only poked above 80C a few times. Put the AVX offset so it's still running at 4.2ghz though I could probably bump that down a bit since Prime95 seems to peak in the pretty low 70's now.

            I've read that you should avoid Prime95 for testing because it's going to push thermal temps way beyond anything you'd ever experience. H264 encoding tests seem to be recommended.

      That's a pretty shit response when you're selling an overclocking chip. No overclocking no point of having a k model. From what I read the 7700 has an issue with the thermal paste between the lid and important bits. People who have replaced that have seen 20c drops.

        between an unlocked multiplier sold as an official feature, and a warranty plan for overclocking, seems to me that they support overclocking.

          I thought the intel warranty plan for overclocking is essentially an extended warranty that you have to purchase separate from the processor, and is a one time use along with other catches.

          With unlocked processors I kind of look at them like vehicles with no governor. Sure you can red line it every time, and keep the gas to the floor but how long will it hold up.

          People have been doing some crazy overclocks with this chip. I'm surprised more have not been failing because they have to be pushing the voltage something awful.
