MP 1,1-5,1 Crash Panic(CPU 16, time 2193865881385)

[superparati]

Hello,

I have this issue from time to time and always when I do encoding.
Today and last week exactly the same error.
I was encoding a movie to be Raspberry pi compatible using the preset H264 videotoolbox or the classic h264.

Almost at half of the encoding the computer restarts.
Below the temperature of the CPU A and Northbridge

What does mean a temperature of 15°C for CPU A Relative to ProcHot when room temperature is about 21C?
Might be the time to update the thermal paste maybe....

I did another test and again as soon as the CPU A relative to prochot temperature is about ~15C or less the computer reboot.
For this one I had my eyes looking at the temp and just before the reboot I saw the wifi getting disconnected and reconnected and immediately after computer restarted.

[superparati]

Any advice or ideas which can help me to fix the issue?

 

[KeesMacPro]

ProcHot is the Temp where it gets nice and toasty.
The CPU and especially the Northbridge gets way too hot..

Might be the time to update the thermal paste maybe....

I don't know how you set up your fans, but rpm min is not good...

 

[superparati]

thanks for your feedback. I've ordered some thermal paste & pad to be delivered by Sunday
But looking at how hot other MPs are especially CPUs and Northbridge I'm in the average.

 

[MIKX]

Your INTAKE and EXHAUST fans RPMs are too low.

The NorthBridge Tdiode's heatsink sits between CPU A & CPU B,

it needs airflow.

 

[h9826790]

If you suspect that's temperature related, for testing purpose, you can set all fans to 50% via iStat menu, then do the same H264 encoding again, and see if there is any crash.

If yes, please check all CPU and NB diode temperature.

Even you use the VideoToolBox option to encode videos, the CPU temperature still that high?

Did you ever open the case, and blow the dust away?

 

[superparati]

This is exactly what I’ve done by setting up the intake and exhaust fans at 1000rpm and the export went well GPU and CPU both mode have been tested.
The computer did not shutdown.

Then I decided to give a trial by removing isate menu and see if the default setting would ramp up the fans but not after 3min the computer rebooted.

I also wanted to make sure the cpu cooler were properly installed by turning the screw. The computer refused to boot. So I reversed what I’ve done.

I think it is time to replace that thermal paste (Thermal Grizzly Kryonaut 12.5 W)
I’ll also replace the NB thermal paste. I bought some screws, nuts and flat washers (plastic and stainless steel).

Hope it will do the difference.

 

[superparati]

With a little boost it works better

.

 

[KeesMacPro]

Northbridge Heatsink- Diode Delta=15 degrees.

I’ll also replace the NB thermal paste.

I think that will lower the Temp a bit more.

Edit:Thermal Grizzly works better then e.g. Arctic Silver for applications with low/medium pressure .
With the Kryonaut I got NB Temp Delta =between 5 and 9 degrees.

If you have confidence, you can actually use liquid metal. Therefore, it will never dry up. Also provide the best cooling.

N.B. do NOT let liquid metal touch any aluminium

 

[superparati]

I’ll try with the one I received today (not liquid metal).
And hopefully it will fix the current issue.

Hello,

My conclusion after taking my time to clean and replace the thermal paste and put all part together it was recommended.
I did a encoding test to make sure everything was working as expected (system ambient temp is, here, at 30°C°).

1- I don't think I've done my best with the NB, the paste was for sure old but the temp did not very much change. Plus I replaced the plastic bolds by a metallic one M3 16mm and one of them is too long. I added some flat stainless steel washers but I'm sure it does not tight up the cooler as previously. I'll try with bolt only 10mm long next week.
CPU at full load the temperature reached 82°C.
the Northbridge Heatsink- Diode Delta is till showing 15 degrees difference.

2- the IHS of the CPU are still in place and I noticed that the thermal pad should be in contact where it is highlighted in red on the below picture (from Instagram,, this is not my tray as it show some delidded CPU). My thermal pad is not in contact and I'm assuming it should.

For those who have a dual CPU tray can you confirm if the thermal pad is in contact what is highlighted in red above?

3- I did one export and the computer did not reboot, this is a good news. But the CPU temp were still high and the fan not very much active by default. Exhaust and intake were very sleepy 600rpm and the end of the encoding only the CPU A & B fans were at 2000rpm. I had, with Istate, to increase the speed of the Exhaust & intake to decrease the temp from 82C CPU A to 76 degree.
Both CPA have a temp difference of 8C at idle and 12°C max loaded.

I'll monitor the temperature in the coming days.

Thanks!
