Hi im new here.
I hope you guys help me.

Recently i have an issue and
i try to fix it, no matter what i do
when i enabled X.M.P CPU Temps will up to between 10c - 12c. Why???? :(

I'm 5Ghz OC but still not stable.
Im at 1.380V i can run few minutes but
Not long, before i stable it
i want to solved this XMP high temp issue.

5Ghz X.M.P ON Max Load 88c
5Ghz X.M.P OFF Max Load 68c

My info
Intel Core i7 7700K (Delid OC to 5Ghz)
ASUS Z270F Gaming. (BIOS v1203)
Corsair Vengeance LED 8GB x 4 (3200Mhz)
ASUS GTX STRIX 960 4GB OC Edition

Please Guys Help me :(

IMC [integrated memory controller] is on CPU die.

try disable hyper threading in motherboard bios
and or
make a note of XMP timings set them manually *lower RAM voltage .025 at a time *until unstable

NOTE: not all CPU wafers OC the same; may have to settle for 4.8 ~ 4.9

Quite simple , you have all four memory slots filled , the strain on your cpus internal memory controller generates heat , it's not an issue it's a fact to consider while overclocking , more cooling ir perhaps looser timings on memory might help. Might.

Thanks I'll try that and tell you if it effect.

Thanks for reply.
I have Corsair Hydro H115i Extreme Performance Liquid Cooler.
And i also have RAM Cooling system.
Dual Fan RAM Fan kit. 4500RPM+10%
My Ram fan hit 4600RPM when CPU under load my cooling is fine and 140 Dual fan hit 1980RPM when it under load.

This is not really a case of RAM cooling or a need for it; although it is a good idea when over clocking to provide adequate cooling solutions.

The simple fact of filling all the memory channels on the motherboard will effect the OC that will be available when volts and heat become a restriction.
Example below:
IMC Load Example.jpg
as the OP your running 4 x 8GB of RAM @ 3200MHz which fits the top profile that creates more strain volts and thus heat on the IMC

Note: If after max OC running 2x 8GB of RAM @ 3200MHz would be more desirable

bro i try everything seems like when XMP of CPU Temps go high there's no way to fix it :(
 
Check VCCPLL voltage. Try lowest value like 1.1V and check stability. I think you may get 1.35V right now.

Also VCCIO VCCSA can cause temp increase. Lower this value to absolutely minimum that still stable.

You have good cooling , but not that good , the heat output at 5ghz on any cpu at this point is already epic enough for your cooling, the four sticks are cooled too but it's not the heat of the memory it's the heat of the Imc.
I have faced the same issues on different platforms and no reasonable amount of cooling resolved that oc to be stable, at that point I had two 360 rads and a 120 rad in my loop but the total package heat of the cpu was too much for the IMC , using two sticks(@1866 my max max) im still able to hit 5ghz three years later though I don't as it's not going to help Me on this old rig.

Just one thought ,is your memory on your motherboards QVL qualified vendor list, if not then the Xmp profile might have been made for another platform ie skylake and could be tuneable to get it stable, id try your Xmp but manually nudge its speed down keeping timings the same but in general all chips run four sticks slower than two including server grade kit so if you're running two sets of dual packed memory it's Xmp was set for two sticks too not four, thats n part why they sell quad matched pairs, so they have timings and Xmp set right for four sticks,( i got two sets of two rather than one set of four so experienced that too.

Thanks for try to help me, and can you please tell me

Where do i find this VCCPLL Voltage?
What it call full name pls?

And what voltage i set to this two?
VCCIO (CPU VCCIO Voltage)
VCCSA (CPU System Agent Voltage)

I'm waiting :)

This is the option?
VCCPLL????

Please anyone!!!! :(
 
Make sure your BIOS are up to date. Some motherboards shipped with a bug where temps ran out of control because of minor changes in the BIOS.

I updated my bios to latest version. V1203 is latest.

Can u please tell me where do i find that VCCPLL option i can't find it :(

VCCIO and VCCSA are there but not VCCPLL
 
According to Nich Shih @ HWBot (the guy who design ASRock OC Formula).

ASUS call VCCPLL as PLL bandwidth. Try lowest value.

Over value mean 1.1v???

There's only one PLL i attach the photo ia that it?

I can't find it i look everywhere.
It should be in AI Tweaker.

Is there any other name for this?

What lower value i put? 1.1
Click to expand...

There's only one PLL
It's call Internal PLL Voltage

*Configure the offset for the core PLL VCC Trim*
 
IIRC PLL bandwidth is reserved for ROG board. My previous Z170-A also don't have those settings. Someone told me that on lower end ASUS board try lowering CPU standby voltage instead.
 
I think i have CPU standby voltage this option.

Mine is ASUS STRIX Z270F GAMING

value is 1.1 for all 3 options you mentioned before right?
VCCIO, VCCSA, CPU ST aka VCCPLL 1.1v for all of them is that right? :) im new for Overclocking...

Here my motherboard is here


https://www.asus.com/Motherboards/ROG-STRIX-Z270F-GAMING/

What is PCH voltage does?

i low tha value but still same im try to 1.350 right now...
 
For CPU Standby I leave at 1.0V or something like that. It doesn't have impact on OC ability (tested with i5-6500 @ 4.8Ghz + ASUS Z170-A + 16GB DDR4-3600 14-15-15-28).

IO SA affect memory OC (in your case = XMP) you can try both 1.1V and try HCI memtest for RAM stability test.

Download HCI here http://hcidesign.com/memtest/download.html

I see you have 32GB. Open 16 tabs of HCI and set each tab to 1800MB. Don't open other programs. Let's it run until 100%. If you found no error then you are good to go and can try lower IO / SA again until you found error then just rise them back. Or if you are too lazy then just leave it at 1.1V

If 1.1V doesn't work then try increase both to 1.11 , 1.12 etc.
 
I don't think my ram jave issues cause i have bought them last month directly from corsair.. I strest test my rams with Realbench no error found.. And i can't stable at 1.350 stuck... :(
 
RAM is good yes but if you want to lower CPU temp by manipulating IO and SA then you MUST check for stability. IO and SA are used to feed IMC that control your RAM.
 
@OP
I feel your pain.
I have an 8700k and was getting temp surges to 100c and the fix was to disable XMP and set the memory timings and voltages manually.
Doing that dropped my temps by 15c max temp and overall average reduction of roughly 32c.
 
Dial the timings in manually.
 
XMP usually increases the voltages for the IMC as well as the VCCIO, VCCSA probably even pll depending on the board

also you should be running some level of negative avx offset unless you enjoy blowing your chip up
try like -2
 
Thanks guys for try to help me

*Cybrnook2002* this friend told me check the ASUS KABY LAKE Overclocking Guide. I hope it will help... Its long journey now ita late night so i will check that tomorrow if i found a solution i will tell you guys.

The Best and Easy solution for this DON'T USE XMP.

But i try to find Hard answer..

Thanks you all... See you next day :)

Hey what is your Motherboard?
ASUS Z370F

Please read this!

"
Overclocking Asus Z270F
With 5GHz seemingly an easy target for our Core i7-7700K, we set the voltage at 1.4V and worked backwards till we found instability, having previously found 5.1GHz out of reach through needing too much voltage. The MSI Z270 Gaming Pro Carbon needed 1.36V to stay stable at 5GHz, but the ROG Strix Z270F Gaming smashed this amount, needing only 1.33V - the lowest we've seen so far. This made a tangible difference in the temperatures too, which fell by several degrees as we tweaked the voltage in AI suite downwards. It needed just 1.21V for stability at 4.8GHz too."

Guys what is this???
A joke? I try 1.395v to stable still im not sure it will be stable cause
It crashed 1.390v
Plese take a look and
please explain cause i have z270f can't stable my cpu is Delid
