So I just have to put 12 on the 3rd times for those 4 right? I'll try those next. I really hope retailers here would accept a special order for the apex.</div>

nope.. you need to set these to the same value as CAS. so if you are running 3866c17, these need to be 17.

Oh, now I get it! I'll try it and keep you posted on what happens.

if you put Nt-H1 under the IHS, I'm not surprised by the poor temperatures. Use a LM or there really is no value in delidding (8-10C to void the warranty? You should see a 20C+ drop in temps.<br>
Also, check your block mount... believe it or not, some folks left the protective plastic on the block face. <img alt="smile.gif" class="bbcode_smiley" src="http://files.overclock.net/images/smilies/smile.gif"></div>
</div>
So it does make that much of difference uh? Cool! The worst part was the delid, now that its done, I will get some LM <img alt="smile.gif" class="bbcode_smiley" src="http://files.overclock.net/images/smilies/smile.gif"><br><br>
Thank you very much!!!<br><br>
PS: That Plastic thing you said is the cover that comes with the motherboard? Jesus peepz really did that?!?!?!?! o_O

Possible causes :<br><br>
1) Bad mounting of cpu block - pull apart and remount<br>
2) Is your delidded cpu's IHS resealed back on or just sitting on top and secured with the socket lid ? Could also be your cpu delid needs to be redone, as in redoing the TIM.<br>
Also what TIM did you use on the cpu die, a liquid metal or a non conductive one ?</div>
</div>
The cpu block sits perfect i think...<br>
I've used CLPunder the IHS and mx4 between block and IHS . No i did not resealed back the IHS , i heard its not needed. Its something wrong with the chip or settings in bios ....

Indeed ! Nh1 or mx4 under IHS gave me like 5 c drop only... not worth at all.

So , i have found an awesome thing for my self , i hope it can help others also.<br>
I even have made a video of it.<br><br>
So my concern and my blaming on i7 7700k chip was mainly the temps i get with it....<br>
till i made some tests with " cpu pll oc voltage"<br>
Switching it down from "auto" made terrific change in temps drop.<br>
Video:<br>
<a href="https://youtu.be/CPbx7xXqCu4" target="_blank">https://youtu.be/CPbx7xXqCu4</a><br><br>
So as you see there is a 20c drop in prime 95 ( about 25 drop in RB , and about 28c drop in gaming.)<br><br>
Lowest i would go is 1.050 on PLL. system would boot but will freeze on prime 95.<br><br>
My matherboard is msi z270 gaming m7<br><br>
Question ?:<br>
Why would temps depend so much on pll voltage?<br>
What tweaks can i do to lower it more then 1.070 and not get system freeze? ( i mean maybe it works together with some other setting in bios)?

What is the default PLL voltage?

</div>
On my motherboard default is 1.200 but on 1.200 i see a 5-10 c temps increase over 1.070<br><br>
I guess on auto the mb sets it at like 1.3000-1.4000

I have noticed that PLL voltage increases vcore indirectly on my z270 asrock k6. The lowest I can do 1.1 and that is what I run daily despite I run my vcore higher than most with similar chips; batch numbers/oc potential. It does indeed effect temps significantly. I have considered modyifing the BIOS to allow lower PLL, but this may be in vain if the temp differnce is directly related to vcore.

I noticed the same thing on my MSI z270 m7 .. the results baffle me as the mins drop bellow room temp. Im wondering if anyone else has tested the cpu like with an independent thermometer ... Im still sceptical if the results are real... but yes mine drops like 10c as well. Im on 1.100v on CPU PLL OC

Did you try to get lower PLL then 1.100?

From what I see you have already lowered this voltage and archived a stable system at lower temperature, fine tuning is about that. But every CPU and system have a limit like you already know.<br>
Every voltage change can made the temperatures lower, so you just have to stop when your system become unstable because this mean you have already reach your environment limit.<br>
Don't ask always for more and more and more.... LOL <img alt="biggrin.gif" class="bbcode_smiley" src="http://files.overclock.net/images/smilies/biggrin.gif">

Yea I had it at one stage at 1.060v for 4.8ghz but kept bumping it a bit after doing 2 hour realbench and it crashed randomly. But it passed at 1.100v. But when I had it at 1.060v it was even cooler. But still got me wondering about the min temps as Im just not sure how it can be lower than room ambient temperature. Which makes me think its wrong or incorrect. One person recons it is skewering the temp sensor so its not correct. The only way would be to put a temp sensor on the cpu to get a independent result to see if its correct I guess.

Yep . Makes me also think of that.....<br><br><a class="H-lightbox-open" href="http://www.overclock.net/content/type/61/id/2972553/"><img alt="" class="lightbox-enabled" data-id="2972553" data-type="61" src="http://www.overclock.net/content/type/61/id/2972553/width/200/height/400/flags/LL" style="; width: 200px; height: 150px"></a><br><br>
Thats at 1050<br><br>
2 cores at +9 sounds weird<br><br>
What kind of sensor can be connected to cpu ? And in what part of it?

you guys are under volting the SIO... and causing the dts to misreport. (this can result in running higher temperatures than you think).

I came home and tried to view the temps with not as acurate for this job thermometer , but here are the resoults:<br>

May be a coincidence also....<br><br>
Ill rayse the PLL to auto now and see if i get same numbers...

unfortunately we can't shoot the processor cores. What ever is 61C in your IRT is not the processor core.

<br>
Whats the SIO? So you are saying that the temp drop is defiantly not correct?<br><br>
Nice idea MaKeN but yeh probably not accurate to the core temp. Not sure how to get another reading of it :S<br><br>
So im confused if thats all the dropping PLL OC volts does it make it inaccurate whats the point of it? Usally any drop in volts is good if its stable. Got me baffled as to if its accurate and what the hell it does lol.<br><br>
Should I then put it manually on default which is 1.20 or Auto. If Auto is that accurate or manually putting 1.20 which is default on board still inaccurate lol ?
