Hi,

Running the following..

Intel 6700k @ stock
Asus Z170i Pro ITX Motherboard
16GB Ram
Arctic Cooler 13 Pro

Just built this up and running intelburntest or prime. Goes from low 30's idle, to approx 60ish and then within about 15 seconds , shoots up to nearly 100!

Any ideas?

This is stock so not even overclocked. Also, checked the cooler is sat right twice and put new IC Diamond paste on both times.

Hi,

It had thermal paste already on so no lol. Tried it 3 times now , first with the included thermal paste , took it off and put new IC diamond on and still the same , taken it off a third time now and applied new paste and still the same.

I'm sat here now and its currently at idle sitting at 23-25 degrees. I put IBT on and it immediately goes up to low 60's , stays there for a while and then BAM high 90's
 
Is the Heat sync actually getting hot? if its getting really hot then your getting good contact and the problem might be down to high voltage or summat. If its staying cool it must be bad contact.
 
Sounds like too much voltage. Could be really poor contact though.

Firstly, Run CPU-Z and run IBT read max core voltage and report back.

I found IC Diamond crap for me. Remove cooler and ensure it is spreading across the IHS evenly. Or atleast a good circle covering the majority of the IHS itself.

When you apply IC Diamond is quite thick. Stick sealed tube in some boiling water for a couple of minutes to soften and re-apply. Pea sized grain in the centre of the IHS. First time I used it, was very patchy and almost was like cement. Hardly spread at all.

I went into BIOS when I installed it and chose XMP profile. I thought that was just down to the ram but it looks like it changed CPU settings as I have just reset the bios to standard and rerun the IBT and its getting mid 70s on full load with stock settings. During the IBT test , the voltage was going upto 1.254v so presume that is stock. Was hoping to get a pretty good overclock as on my other system (6700k with kraken x61 as a cooler) am getting mid 60s on 4.5ghz @ 1.35v

Built this mini itx build as short of space where it is going to be used.

I do find IC Diamond a bit hard yes but cools fine on my other rig (6700k x61 kraken)

Just if you can like my post above check the spread on the IHS. I personally dont like IC Diamond as it was too thick for me. If its not spreading well follow my method above.

Stock settings should be cooler than that with the cooler your using even with lack of space. Even XMP overclock shouldnt see 90c.

I use GC Extreme personally.

I did check the spread on the times I took it off and both seemed ok. The idle temps seem perfect , low 20s , its just the load temps.

Ahh ok no probs. Probably just the new i7's being a little toasty. For a more realistic test. Try Realbench.

Doesn't overstress like IBT.
 
Try real bench as suggested. Skylake chips are a bit cooler running than the previous hw/dc chips. But ibt and certain versions of prime95 would hit the 90's in seconds on these older cpu's.

Ive just reset the computer, rerun the exact same test , changed no settings and its high 90's again :confused::mad:

Check voltages. If it has set them back up again. Ensure XMP, overclock mode etc is not enabled and reset re-test etc. If nothing reset cmos and try again.

If it still keeps upping the voltage re-flash the bios to latest version.

Let me know what core voltage it is set to.

Core voltage at idle is 0.64 and at full load is 1.254

Am running latest bios

XMP is disabled but have manually adjusted the ram to 3000mhs from 2133

Realbench I am getting high 60s to mid 70s. I'm concerned about IBT and Prime as my other rig did these with no issues. I know IBT and Prime don't represent real life situations all the time but there may be a time , my CPU is getting hammered and don't want it sitting at nearly 100

Matt
 
It'll only do that if your CPU gets hammered by AVX instructions. And you'll know if a program uses AVX instructions.

The temps you are seeing are explained. 60C is when the CPU is fully loaded and filling up the RAM to begin the stress test and the 100C spike is when the AVX stress begins.

Every 115X CPU after sandy has been very bad at dealing with the heat output from AVX. The options are to delid, change to X99 or just live with the fact that a very specific instruction set doesn't work.
 
Sorry to put my ore in im not 100% on Skylake but am i right on thinking if you overtighten the heatsink it can cause heat problems and also problems with memory controler as well or have i got the wrong CPUs if not try to slacken the heatsink off a little to see if it makes any difference
 
Ive put everything back to stock, set the voltage to 1.2v (peaking at 1.216 in cpuz) and ran IBT for the last 30 mins. Getting approx 120gflops, don't know if that is good or not? Also temps are maxing out at low to mid 70's. (71,70,76,73)

Thinking I'm just limited by my cooler?
