Micro Stutter/Lag when Gpuz is open

So i changed the thermal paste and pads on my MSI R9 390 and refitted in. Ran unigine heaven benchmark to see the change in temperature.

normally i use hwmonitor to see the gpu temperature. but i opened gpuz this time and noticed a micro stutter at an interval of 3-4 seconds continuously until i had gpuz open.

i cleaned the pcie slot, DDu ed the driver but then as i gave up and started playing a game without gpuz i realised that it was cause.

could this be something related to GPUz using the gpu sensors??

temperature seems normal while gaming Gpu@81c Vrm 1@75c and vrm2@65c.

any help?

yeah that's possible. turn them off in settings and see if that makes a difference, maybe you can even identify the exact sensor causing the issue

thanks for the reply. I tried disabling all the sensors...the problem still persists....any suggestions?

tried closing radeon software through task manager..no help there either.

Do you have any other monitoring software running?

Bumping for interest. I don't run any now but annoying microstuttering was a big problem for the R9 series cards. System tray software and background monitoring were often the culprit but I never always found the cause and just assumed it was a Windows service.

The fact that the problem never happened on newer cards like the RX480, even in the same systems makes me feel that the 2nd/3rd gen GCN driver was overly sensitive.

i am thinking the same. some background service should be the culprit.

the next obvious step :D is to reinstall the windows. might do it tonight. i ll let you know the outcome.

Try in Linux (you can also run this Live from a USB flash drive) -- Ubuntu is good enough for such testing:

Try Windows PE too, such as -->

IF Linux and Strelec PE are both fine, something is wrong with your actual/current Windows OS installation.
Obviously, if Strelec has no stuttering with GPU-Z not running, but starts to stutter with GPU-Z running, then you will know GPU-Z is the culprit. ;)

EDIT: Also, it is possible something on the video card got damaged during the replacement/cleaning process.
You probably did this more than 20-40 times and are good at it, but this does not rule out a defect of some kind in your GPU after the procedures.

EDIT #2: OR also possible card is simply dying of "old age", regardless of those procedures you did with it. :)
