Asus z370-e i7 8700k oc'ing issue

Are your water lines on the rad on top or bottom - If positioned on top you may have air in the loop causing the higher temps.
Just a thought

Are you sure your ambient room temp is 33c?

If it's a true reading, you probably can't expect much better that what you're getting now.

You may be right the radiator is on the top. Since the fans are not fully screwed in and possible air leak is causing the radiator fluid to not cool effectively in the left end towards the case rear due to fan partial placement air may not fully pushed out of the case due to this odd arrangement.

But few say even with 1 fan the cooler will work so it is not the problem.

As i can lively see the temps are 43 and sudden spikes to 55 and then back to 46 . i dont understand that 10 degree up and down. but this is package temps not core temps

worst is it reaches 69 and back to 44 i can loop in video

Now the temps seems normal. But voltage keeps flucuating and hits 1.4v even though i manually set to 1.26v for 4.4gh auto ratio

What settings to be off to not to overshoot the voltage beyond 1.3v.

its under medium load under 79 degree

But on cinebench its hitting agiain 90+ degree. I believe something wrong in temps due to over voltage. previously i have it under 83 which is decent.

Does switching off the SVID makes not jump in voltage or speedstep which is shooting the voltage

I dont want always 4.4ghz it has to downclock when not loaded well. So svid is must for muti frequency.

Had the same issue on my z370g .
The key was a fan above the VrM ( left side of Cpu )
Thermal throttling of the vrm was the prob.
Take a try with a external fan*

Only turn svid off if using manual voltage control but it doesn't need to be turned off, SVID can always be left on AUTO
Have you set SVID Behavior to best case scenario, LLC 5 or 6 , 1.26v should hit peaks of about 1.32v.
There will always be some voltage variations, it will never be exactly what you set, and any monitoring software will never be 100% accurate, don't worry to much about short peaks as long as temp readings are safe

When LLC on auto only i dont have hicups in games. Ie game freezes for few sec i hear background music but screen freezes for 1-3 secs and resumes. Never creashed the pc or game on this freezing thing.

Since i have the wattage monitor and gpu tool in handy i can cleary see the gpu is cut off power or usage drops from 99- 30 or below so no work from gpu.

I see this behavior on svid off and llc set ot any value . I hate that game freeze thing when the board overtage the power usage.

As the wattage jumps from normal avg of 345watts to 420watts peak some times 450 watts. My psu is new and just 1 year old. It has nothing to do with this.

As the its from corsair RM750x is capable of running the current setup of i7 8700k and gtx 1080 mini card with nill issues. as the peak is less than 500 watts


I dont know what will happen if i ever wanted to oc this in near future with 5ghz. i dont even a custom loop is going to benifit out of it.

Only deliided is getting 20 degree temps cut . Which i can never do since it voids warranty. I even dont know when one can claim the processor warranty . As oc'ing is not covered under warranty as any damage will not be covered as its due to beyond stock settings.

Hello there,

screenshots from your bios settings and a picture of your rig are in order to help further.

I run 5ghrz@1.305 adaptive with svid/ CIO 1.2 / VCC1.175 / 16GB RAM@3200 with 1.345 with mid 80ies Max Temp:

The little 40x40 VRM love on the upper right corner helps even without removing the plastic cover.
So says my manually installed VRM temp sensor.
Having a 90 degree turned MoboCase (FT02)... well THAT is awesome on air.

I have a 9 year old Noctua NH-14 (Buy NH-D15 now) .
It works without air bubbles getting into non-servicable loops.

Here you go

Thanks man,

NEAT RIG!

I haven't checked all yet.

Please try:
IA AC Load Line 0.01
+ DC Load 0.01


since from the pics only CPU vcore has been raised and nothing else please turn that one on auto. Even if it hurts.
We will come back to that one later.

Check and disconnect almost all harddrives for testing from both cables.
Please install (with complete uninstall within install procedure) new graphics drivers
Use the software Coretemp to see your vcore min and max draw please and kindly share that number with us.
Btw It shows higher temps than Aida64 on my versions.

Play and see if the glitch is gone and give us feedback about the auto vcore. It in iteself will tell us the future steps to be taken.


Some suggestions on the side

The Case:

Fans (like microphones btw) all have a distinct 3D area of optimum effectiveness. the nerds can search the interwebs for "directional response pattern" i believe.

Now someone did find out that one can raise that area of effectiveness by quiet a margin.

positive air pressure! (negative pressure mode exists as well)

we are talking about bullying the air into every nook and cranny by shoving more air into the case as air can get out......
And I do not think you could build pressure high enough for all those openings to compensate Sir.

On the pics I do not see air reaching the vrms to smooth out the temps.

So you either have to give some serious aerated high rpm love to the upper left corner directly
(try 40x40 full speed with a test mount first)

Or you research the topic a bit and try to close some of those holes with some more fans on 50%-75%.
Buy a cheap motherboard sensor and make a day out of it testing around with different openings shut close with tape vs fan speeds.

I will not recommend using smoke to check airflow.

Best Regards

Carlyle

ps Please share what Power unit is running your rig.
..... and where the frag is it? I do not seem to find it on the pics
The Ram definition in full if possible please.
...HA and if one does not show the radiator it must not be presentable?!
