2700x Temperature Reading Anomaly (-10, -57, +107 & +196)

So i hope I am following correctly, have just downloaded this driver and installed (October build):-
https://www.amd.com/en/support/cpu/...-ryzen-7-desktop-processors/amd-ryzen-7-2700x

As this one looks older (August Build):-
https://www.asus.com/Motherboards/ROG-STRIX-X370-F-GAMING/HelpDesk_Download/

It seemed to update Ryzen Master but I have been doing that from Ryzen Masters settings so not sure if its more up to date or the same build.

New bios for Mobo so just going to get that installed next to check off both... man I hate doing a bios flash (fingers & toes crossed!)
 
So just to be sure have gone through pretty much all the drivers/software updates this evening including:-
-Chipset (Ryzen Master) direct from AMD
-Mobo Bios

Also let the Qfan controller run its optimising in the bios rather than using Ai suite so hopefully I will get the most out of my fans without the hard crashes I was getting when I first put the build together.

However a quick test with Prime95 brought up another -10 reading after not very long so am guessing this may just be something to do with either the cpu or mobo that I will have to live with and hope it doesn't cause any unforeseen issues...? Just going to see if I can get one of the high temp reading anomalies to ensure that it still runs through these rather than the minus degree readings.
 
After some more testing last night I could only get anomalous results of -10 and -57 rather than any of the high anomalous results (197 etc).

However as a plus point setting the fan curve in the bios has seemed to help the stock cooler keep the cpu a bit better cooled under load so thats something!
 
If you had almost 200C your post would begin by: "My PC isn't turning on.. burning smell", etc..
And you would only hit -57C if you had a a bottle of LN2 which happened to be leaking right on the CPU socket.

The fact it spiked both ways tells me you've definitely got a software glitch of some kind, so I wouldn' worry too much.

IMO: This is definitely due to a Ryzen Master software glitch of some kind.
Update BIOS + Chipset Drivers, try a re-install of Ryzen Master software suite, and see if you get the same reading.
 
Tonight I am very gutted. Hard crash problem came back... playing kerbal the screen goes black and pc won't respond forcing me to turn off at psu.

So disappointed it's hard to put into words...

Have reverted the fans all back to standard in bios in the hopes that the hard crash issue is related to Asus fan whether on ai suite or done in bios. At a guess it gets a reading of 198c and the fan controller causes the system to crash but no idea.

See here for original thread:-
https://forums.overclockers.co.uk/threads/new-build-1080ti-lock-up.18831732/page-2#post-32187725

This is the most expensive system I have ever had and I have to say these issues are really upsetting...
 
Hope this might be something, found asus motherboard fan control running in task manager so disabled it in services to prevent it running. Reset the curve again in bios in the hope that without the service running the problem will stop again...

Fans still speeding up whilst temps increase so stopping that service should not effect cooling, will have to continue to monitor...

Wondering if this is part of the ai suite has managed to get itself back on with recent updates to Asus aura.

EDIT: after a quick test the fans sped up when stress testing but then didn't drop rpm when the load dropped. Reset all fan settings to standard in bios and still ha ing the asus motherboard fan controller service disabled. Just running another test.

Running the fans on standard profile and now they are spinning up and down with the temps as before...

I really hope it's the asus motherboard fan control service reacting badly to the cpu's anomalous readings that's causing the hard crash as I had presumed before... Incorrect readings I can ignore, hard crashes I can't.
 
Quick test tonight and quickly got a 198 degree reading whilst playing kerbal, not registered in Gpuz only in ryzen master but no hard crash with fans set to standard. Annoyingly I just don't have the data to prove my theory that with asus trying to control the fans, either qfan in bios or from fan xpert in the ai suite on anything but the bog stock setting, it causes the system to hard crash when if it detects a reading of 198. Not exactly sure why this would be as I would expect it to just continue to be at max as it should be at anything 70+.

That or I've just been very lucky that it's not happened since I removed ai suite and last night, almost impossible to 100% diagnose as when it hard crashes I can't look at the sensor data the moments before it crashed or be able to reliably recreate the hard crash. If it's not the fan controller software causing it then it's very random. If you read the old thread you can see my troubles with trying to narrow it down the first time.

Ho hum im about to leave a kerbal in orbit for a good couple of hours to try and confirm (hopefully) that it is stable with the standard fan curve at the asus software disabled in services. We shall see...

Has been running Kerbal now for a good couple of hours and didn't hard crash yet despite getting almost all of the strange readings in Ryzen Master so far.

Another thing to note is that other monitoring programs (Gpuz and HWmonitor) very occasionally get these results but that might be down to the 1 second check time and these sensor results likely lasting for a much shorter time so just depends on the moment they refresh as to whether or not they are detected.

Going to keep kerbal going a while in the hope I can feel confident that it is infact the fan controller that's causing the hard crash.
 
Ran Kerbal for another hour with no issues, only thing I noticed was another anomalous reading but this time of 107. As with the others it lasted one second in the log and the reading either side was 62 so clearly not an accurate reading. Strange but lucky in a way that ryzen master isn't reacting to these in any way as it's thermal limit is set to 95 and yet it's the program that seems to pick up the most anomalous readings!

On the plus side no hard crashes tonight, got to get an early night so cannot do any more testing today.

Ai suit have caused issues conflicting with other apps in the past. I'd recommend uninstalling it. Also, do all your oc'ing or simple adjustments using the BIOS not Ryzen Master. Do not combine RM with other monitoring app. For monitoring temps and voltages just use one app. The most recommended app for Ryzen is HWINFO64. That's it. Adjust fan, again, using BIOS.
 
Why don't you just try a clean install of Windows on a spare drive, leave all the junk off, just install what you need. Then do some testing with Prime etc. Try not to install too many monitoring programs at once!
 
Thanks for the feedback guys I really do apprichiate it.

Before contacting Overclockers is it the mobo that gives the cpu temp readings? Don't want to replace the motherboard only to find it's the cpu that's to blame?

Have uninstalled Ai suite when i first ran into the hard crash issue but was thinking parts of its fan controller software made it's way back on with the recent asus aura update or after trying to set the fans up in qfan in the bios. Not sure which either way it brought back the hard crashing problems.

I have done no overclocking to the cpu this is on the standard profile that it comes out of the box with.
 
Also I think I have just confirmed the issue isn't just the fan controller, just booted up and got a hard crash after about 30 seconds on the desktop. No load on the cpu or anything and this is with the stock fan settings. Worried now that it's an issue that is going to be hard to replicate as it must be somewhat separate to these strange temp readings.

Will contact ocuk with this thread attached and see what they recommend, have been trying to avoid an RMA / rebuild but really no choice now. Just hope OCUK can help despite the bundle being bought back in September, I've spent soo many nights trying to log the data to no avail.

Keeping my fingers crossed!
