I'm out of office until Aug-24. Will respond to all requests upon my return. Thanks, Martin

Mainboard (probably?) overheat
#1
Hello guys, so first of all my rig:

Intel Xeon Processor E3-1230V2 [8M Cache, 3.30 GHz]
MSI RADEON™ RX 480 GAMING X 8G
RAM Goodram 16GB (2x8GB) 1600MHz CL10
PSU: Corsair VS 650W
Motherboard: MSI Z68A-G43 LGA 1155 (G3)
SSD Samsung 850 evo pro
Operating system: Windows 10 Pro

So I had a weird problem when playing some demanding games like Battlefield1, suddenly my fps droped significantly, to the level I wasn't able to play. So I started to monitor what is happening on my system while the fps drops. What I found out is that when the fps goes extremely low all 4 cores of my Xeon drops their clock speed to 1,6Ghz from 3,5Ghz, but why? I look at the temps and an all 4 cores the max tmp is 62 dgrs, nothing special, I tried to reset bios settings nothing changed, and then I found out the issue, but I don't know what is this? In hwinfo my mainboard have one row named T1, and it has very high values while playing games, and when it hits above 100 dgrs the clock speed drop happens. I have no idea what this T1 could be and that's the problem. Tried to find anything on google, but what I found out is that this T1-4 depends from the mainboard. So any idea what this could be, and potential fixes?

This is the screenshot just after the system startup, and with browswer opened only and still it has 56dgrs. When playing battlefield 1 it hits even 112 dgrs.

T1 is just a generic value and it might not provide correct values on your mainboard.
I'd suggest to first compare with the MSI Core Center or similar tool from MSI if it shows that temperature.

You should also check the status of "Thermal Throttling" in HWiNFO sensors. If this is active, then this is the reason for clock throttling.

The thermal throttling says 'no' even when the cores goes down to 1,6Ghz, as I said the core temps are at about 60 dgrs, yet when the T1 hits above 100 dgrs there is throtling on cpu

Then please check with MSI Core Center whether the reported high temperature is real.

Can you give me any download link to it? Cause all I find is MSI Dual Core Center and it says it don't suport my system

Try the MSI Control Center: http://download.msi.com/uti_exe/ControlC...v25_mb.zip

In Control Center there is only few things, nothing with temps like T1 :/

See if any temperature reported by Control Center correlates with T1 in HWiNFO. If not, then T1 should not be valid.

But this T1 corelates with cpu throtling

T1 above 100:

T1 below 100:

I'm afraid, this is a mainboard-specific function and only MSI knows exactly, so you should try to contact their support.
If it's really caused by a flawed sensor that is initiating CPU throttling (based on wrong temperature), then you might try the ThrottleStop tool to disable Bi-Directional PROCHOT signal and see if that helps.

Well ... thanks for all the help, when I disable BD Prochot everything runs perfect but you know ... this T1 reaches even 117 dgrs, if it is flawed sensor it is not problem but ... what if the sensor is fine and my motherboard will fry someday? Eh ... I don't know what to do, and MSI is silent Sad

I'm sorry, I can't help with this. Only MSI knows...
