          Thank you, Andrew. I will make these adjustments and report back on the results. Hopefully this (and a quieter CPU fan) will put everything in order.

            Alberto,

             

            I also have the 7700k and am experiencing temp spikes with the 7700k, i am also noticing a huge surge in cpu wattage and believe the correlate with the temp spikes discussed. -- I have attached my SSU file using the program you linked in your response to ZeoxZarix regarding his temp spikes, please add my case to the database. My build is as follows:

            My build is as follows:

              So the PLL OC voltage actually does change temps or its a sensor issue?

              there is a lot of confusion and I don't know what to believe although I think it does change temps..

              Can You Guys Update Me Please whenever or not its changing temps or sensor issue?

              EDIT:

              Guys i changed my pll oc voltage to 1.1300 i opened MSI commmand center and realtemp and they show different temps while idle.what the hell is this?

              Btw the temp on command center seems to be like i didnt even change the PLL OC voltage..

                Lowering CPU PLL OC voltage lower the temperatures on CPU package sensor and core sensor.

                But it also change CPU temperature on motherboard sensor, so i do not think at all it can be a sensor issue, because it could not influence two different component sensors.

                I think that, as is obvious, setting the right voltages, as datasheet says, just lower the temperatures to a normal range.
                What we should ask is why many motherboards overvolt the parameters of the kaby lake without reason, when parameters are setted on auto.

                We should also ask why intel uses a not good tim on high-end products.

                We should also ask why no producer is interested in the issue.

                  Those questions were asked on the ~second page of this thread.

                  And you know, what was the answer? - Because we can!

                   

                  That's OK for Intel....sort of...

                  But why e.g MSI/Asus/Gigabyte cannot release a voltage fixing BIOS!?

                  They are a crap load of cases, when MOBOs overvolt CPUs.

                  What's the problem?I just don't understand.

                    MSI has responded with the following (I copyed from the 300+ page Kaby Lake overclock.net thread):

                     

                    Thanks for contacting MSI technical support.

                     

                    Regarding your concern,about the PLL OC voltage,we consulted the relevant department,yes,if you overclock the memory,the PLL OC voltage will rise automatically to improve the stability of the system and to ensure the success of your overclocking,we are sorry,the CPU temperature will be affected by PLL OC voltage,this is normal.

                     

                    Even the same model,CPU and memory stability is not the same´╝îif the PLL OC voltage not rise when the user overclock the memory,some CPUs and memory can not work stable after overclocking.For some users,if the PC still can work stable after the PLL voltage is reduced and they mind the CPU temperatures,users can adjust the PLL OC voltage manually,please don't worry.

                     

                    Best Regards,

                    MSI Technical Support Team

                     

                    NOW you could make the argument

                    If turning down CPU PLL OC skews temperature sensor readings: what then should the "optimal" or "genuine" voltage be, where sensors display the actual temperature? Default 1.100? BIOS AUTO without XMP enabled 1.200v? AUTO with XMP 1.300v? Or 1.000v +/- 5% as per the 7700k specification handbook? I have done my reading on this now and concluded for myself that I'm keeping PLL OC to a manual minimum. Would love to see an official Intel or MSI response, since the PLL OC value also affects temperatures on stock 7700k. They can't dismiss this as a problem only occuring when overclocking at your own peril.

                      Again they say about overclock.

                      Half of this thread are @ stock.

                        Hi, first of all I want to Thank some people for making this topic, and most of all I want to Thank this guy:

                         

                        1 007. Re: Thermal sensor issue i7-7700k?

                        AndrewRossi

                        Let me summarize:

                        1) Vcore for stock settings must be 1.200v. When you see more then 1.200v so your motherboard is overvolting your Vcore.

                            Stock frequency is 4.2ghz up to 4.5ghz with turbo boost.

                        2) If you do not see adaptive mode so your motherboard does not support it. So you ve to use the old way (offset or fixed).

                        3) IO and SA settings (these are called in different ways in different BIOS, like CPU IO, VCCIO, etc) must be under 1.050v.

                        4) CPU PLL OC (that in your bios is called VCCPLL OC) must be under 1.100 as datasheet says (some user here is stable at 1.080v, i am stable at 1.050v).

                         

                        If you have different values (like your Vcore and your VCCPLL OC at 1.250v) you are out recommended voltages for i7 7700k, so it means your motherboard is overvolting your cpu.

                         

                         

                         

                        Why? Because it works! This how It looks on my machine:

                         

                        PC Spec:

                         

                        CPU: i7 7700K @4500mhz

                        CPU Cooling: Cryorig H7

                        MOBO: Gigabyte GA-Z270-HD3P

                        RAM: 2x16GB Corsair Vengeance LPX DDR4 3000MHz

                        GPU: Gigabyte GeForce GTX 1070 G1 Gaming 8GB GDDR5

                        PSU: Seasonic G-Series G-650 80Plus Gold

                         

                         

                        And some screens - first one is while I was doing some googling' and listenig to music:
                        01.jpg

                        This one is while I was playing Tom Clancy's Ghost Recon Wildlands:

                         

                        02.jpg

                         

                        03.jpg

                         

                         

                        So, as You can all se the VCORE is 1.200v - and its the best value for 4,2-4,5 Ghz, second and the most important, this is the clue to all of this - VCCPLL OC - Im stable at 1.090v. No spikes, temperatures -10degrees. First of all I was trying to get 1.070 but my PC gets freezing.

                        I was getting about 70-75 temperature while playing with spikes, and now it's like 60-70 with no spikes  My Cryorig H7 was geeting crazzy with RPM with only browser open, now it's gone.

                         

                         

                        So yeah, this is the fix and values that's works for me, and thanks again for it @AndrewRossi

                          i try to make exactly like you,

                          1.2V   1.2 V   1.09V

                           

                           

                          but my computer instantly freeze.

                           

                          do you know why ?

                           

                          here my configuration :

                           

                          7700K with kraken X52

                          gigabyte Z270X - gaming K5

                          i have a lots of spike on my 7700K too, to 60°C

                          during stress tests, i up to 80°C

                            Make sure You set same values in BIOS and in the Gigabyte app, that works for me so far. And be sure You change and save ONE value at time. And BTW the 60 it's not bad mate, from what I heard people was having like from 40 to 90, so thats a pain in the ***. Im having now 60-65, and that's totaly normal while playing, I was over 70 before so there is the diffrence.

                              This just an off-top but I was wondering and I have to write this. Maybe this is not just a CPU problem, maybe its a Intel Chipset problem - Intel Is closing support for Z270 at the end of this year? " Yeah, we mess this up, we ****** up this platform bad, lets forget about' it and lets go forward with something new" Maybe the Z270 chipset is the problem. Since the problem is on all MOBO, no matter if this is ASUS, MSI, Gigabyte or EVGA Just wondering, share Your thoughts.

                                  The overvoltage issue can be simply fixed by motherboards producers with a BIOS update. So why didn't they do it?

                                  That's my theory about it. It is not the truth, it is just a theory. We know that some crappy Kaby Lake (a few percentage) need high voltages to be stable with high RAM frequency and we know that other devices can use the PLL voltage and clip to what they need, so maybe they purposely decided to overvolt voltages.

                                    Btw the temp on command center seems to be like i didnt even change the PLL OC voltage..as it shows 40C on command center and 31-33 on Realtemp..any idea?
