CPU Rebooting after 20-30 min under cpu load

[Shroux]

Hello, i've been watching linus tech tips for a long time ago and although i didnt wanted to disturb the community surround them nor giving them more job that hey already have, im being forced to.

 

So, recently i updated my CPU from an i7-6700K running on a MSI Z170A M3 to an i7-9700k on a Gigabyte Z390 Aorus PRO, as well as my GPU from a gtx1060 6GB to a rtx2080; packages arrived, mounted the cpu, placed the heatsink, placed the cpu cooler, blablabla, everything was alright, altho i had to do some cable management to deal with the space provided and in order to improve airflow. Booted it up after placing everything, POST was fine, clean w10 install was made in order to remode all older drivers from MOBO,GPU and CPU, installed HWMonitor (just in case) and XTU(so some stress test could be done on the cpu,

after some testing with the tools provided by XTU temperatures were as high as 70ºC which is fairly fine for me; besides the frequency test who got temps between 90 and 100ºC causing thermal throttling.

 

After those benchmarks i went onto the BIOS and disabled all Turbo capability that comes enabled from default so instead of 4.9Ghz on 8 cores it will only get 3.6GHz; less TDP being drawn from the PSU, less speed, better temps, i thought, went to do some testing again and the results were top temperature 60-63ºC even on frequency test.

 

That seemed cool to me so i went and decided while i wait for a new liquid cooler and case to come, i will keep this thing up at 3.6Ghz and probabily can play games normally; then after they come i can get everything to preset and re-do the benchmarks.

 

Problem is, it keeps rebooting after 2 BO4 matches, which are a total of 20-30 minutes, under load, but around 60ºC; ill leave details over my setup right down here so if someone can lend me a hand it would be awesome and thanks for the time to read across all this text.

 

So in resume, it only reboots under stress or full loads, or that game, because i had it downloading drivers and stuff a whole day working and didnt rebooted nor did anything weird. Can also perform low-demanding tasks like doing some .docs or browsing without any kind of problem.

 

Details:

MB: Gigayte Aorus Pro (Rev1.0) w BIOS F6 flashed

CPU: i7-9700k@3.6Ghz 1.2V

GPU: Gigabyte RTX 2080 8GB GDDR6

CPU Cooler: (RN)Tacens Mars Gaming MCPU2 (Incoming) Corsair H150i Pro

RAM: 4x8GB Gskill DDR4 2133Mhz

PSU: Aerocool Project 7 850W Platinum (bought less than a year ago; worked wonders with old rig)

Case: Antec gx505 (Incoming) Fractal Design R6

 

Additional Details:

Inny Fans: 2x Front Panel 120mm Tacens Aura 2 1200RPM

Outty Fans: 2x Top of the case 120mm Tacens Aura 2 1200RPM; 1x Behind the case 120mm 1200RPM; 1x Side Panel Fan 120mm Tacens Aura 2 1200RPM

-All drivers are up to date on windows 10 64 bits activated.

-BIOS is flashed from the f5 it comes with to the newer f6.

-Tried running all fans at full speed, didnt get much of a difference.

-All fans are connected to the motherboard and running on auto.

-C:\ (SSD M.2 Samsung Evo) was formatted in order to do a clean install of w10 after upgrading the rig, but another 2 HDD werent touched as they only have programs i had installed, not any driver.

-Ran Memtest to ensure Ram sticks were fine,  everything looked nice

What motherboard are you using? your post makes it sound like you are using the same motherboard you already had for your i7 6700k

My bad; current MOBO is Gigabyte Z390 Aorus Pro (Rev 1.0), older one was MSI Z170A Gaming M3, should edit that to make it clear, sorry ^^"

I'm having this same problem with a 9700K. I've got a completely different set up than you do:

• Asus Maximus Hero XI Wi-Fi
• 32GB Corsair DDR @ 3200MHz
• EVGA 1080Ti

I've got the latest BIOS like you do and I'm running memtest on it now. It seems to be completely unrelated to thermals.

Tomorrow im getting my Corsair hx1200 and today my new case and Corsair h150i, so ill know if it was thermals or power; either way i'll let you know and i only hope it doesnt use more than that wattage or im returning it; i''ve seen builds with this cpu and rtx2080 with 850 or even 750W PSU, maybe a defective batch; i dont know neither care, only wanted to change MB CPU and GPU and im almost building a whole new pc cause of airflows, thermals, and idontknowhatmore just to MAYBE pray it to work.... if i knew it i would've bough an i9-9900k, runs the same temperatures and has hyperthreading, not happy at all with that buy... its killing me, seriously.

Well, it wasnt the overheatting issue, that's for sure, it keeps rebooting at aprox 60-70ºC at full load, anyhow im glad i dont get to the 90-100º anymore cause Thermal Throttling isnt a good thing anyway, but 1200W PSU is coming in a couple hours, i'll see if that solves it for me, if it doesnt ill just return the proc and let the provider know its somehow malfunctioning hoping for a  warranty to cover it or maybe a return or something....

Had Corsair 1200HX arrived this morning, with the H150i AIO, still rebooting...

[Big Head Tech]

For rebooting, try rolling back the graphics driver if it only does it during graphically intensive scenarios. Then take out all 4 ram sticks and test 1 at a time. Use Aida 64. If all pass, try in combos of 2. Then try remounting the board. Could definitely be shorting.

I updated Nvidia controllers and seems to be ok so far although not sure still, i'll inform if happens again, thanks for the help  to everyone

Hello, i'm having the same problem with i7-9700k and Aorus z390 Pro v1, did you fix that?
