Aerowyn Posted March 16, 2017 Share Posted March 16, 2017 Current running a gigabyte z270 k7 MB with 3200mhz corsair vengeance ram When running stress tests with steady 100% load the temps fluctuate like crazy from mid 50s to the 80s.. here is a screenshot of the intel tuning utility http://imgur.com/a/u5guA Link to comment Share on other sites More sharing options...
Aerowyn Posted March 16, 2017 Author Share Posted March 16, 2017 I tried with no OC i I also tried with auto voltage and setting voltage to 1.25 and still does the same jumps the jumps just don't go quite as high they peak around 70 but still jumps from 50 to 60 back to 50 to 70 and back and keeps doing that Link to comment Share on other sites More sharing options...
c-attack Posted March 16, 2017 Share Posted March 16, 2017 This is normal for Kaby Lake. If you put "7700K" into the search box here (or anywhere else) you should find a large number of threads asking about the same issue. This is not a cooler problem, but related to CPU instructions and some loading aspects. The remedies for these things seem to be somewhat motherboard specific, so that may be the best place to start.

Aerowyn Posted March 17, 2017 Author Share Posted March 17, 2017 so found this thread.. so yea seems like issue with kaby lake https://communities.intel.com/thread/110728 Link to comment Share on other sites More sharing options...
c-attack Posted March 17, 2017 Share Posted March 17, 2017 Well, that was good for a laugh... at least the part where the Intel guy tells him he is causing the spikes by running his memory at 2600. Unfortunately, that does encapsulate a large part of the issue and it is not something you can really address. I do think it will improve. The first 6-8 months of Windows 10 made my current HW-E do the same kinds of things. Open Chrome - 6 cores to 50C for a blip. All those things went away. Whether it was MS, Intel, the MB makers, software writers, or a combination of all of them, I'll never know. It was not a serious issue then and does not exist now. The loading aspect is something you might have some control over. Even if you do not intend to overclock, setting a specific adaptive voltage for your CPU frequency may take some of the range out of the temp swings. Most everyone is facing that dilemma and there are some guides out there if you are not comfortable in the BIOS. That works hand in hand with Load Line Level/Calibration on most motherboards. I don't know the Gigabyte line well at all, but most of these have some level of control over this feature that will keep input voltage on a tighter leash and that has a similar effect on the rest of the voltages. This part is very motherboard specific and you should seek a Gigabyte specific source. As for what's happening with your cooling, remember to keep an eye on the H115i temp. This is the coolant temperature and the difference between the initial idle value and your load value represents the most you could ever reduce CPU temps with any kind of fan speed. While the core temps are hot, the 7700K stil does not put out a ton of wattage like a 6-8-10 core processor. Chances are the coolant delta will be small and you won't get any CPU cooling benefit from blasting the fans all the time. Link to comment Share on other sites More sharing options...
