    Good explanation! Here is my scenario.
    i9 32gb ram with stock voltage.
    Aida64 Stress Test.
    CPU 80c ish average upper 70s
    Dimm upper 60s low 70s
    CPU average clock 2.9ghz


    I then run Unigene Heaven by itself and use Aida64 to monitor and my Dimm temp levels out at 93c and GTX 1050ti at 76c.

    I cant run Realbench stress as it causesy DIMM temp to shutdown the system i think 100c?

    I did a repaste and cpu and gpu temps look fine but the DIMM see to just scream north with a heavy gpu/cpu load.

    DIMM temp in AIDA64 is mislabeled. The DIMM temp is actually the first ambient temperature near the majority of the VRM.

    You could try the Iunlock mod that I did and it will help drop that temp, it is a lot more involved though.

    Is it labeled correctly in HWinfo64? or what is it labeled as in HWinfo64?

    I think it is labeled as Ambient 1, but don't recall offhand. I thought I had a picture somewhere of it.

    Hmm.. Not sure. As the "Dell EC:Dell XPS 9570" sensor area is grayed out.

    Not sure why it would be greyed out, but I know for a fact that AIDA64 is mislabeled.

    I was able to add that section to be monitored. Here is where I sit now.

    Ok, I Did repaste the thermal compound, and it does not help to change the extreme throttling, and I assume this is due to power throttling. Maybe it might change it after I change apply thermal pad.

    Ok, I did everything to make my XPS 15 stable - Clean windows 10 install, update, replace thermal compound, thermal pad, and undervolting -, and in conclusion, XPS 15 9570 CAN NOT have stable 142fps in overwatch in lowest setting at FHD. Still, the laptop is very very stable, and maybe if I get an external gpu docking station, it might be better due to no stress to the gpu.

    At least it is stable. What sort of FPS are you getting out of it?
