    I am currently in the middle of undervolting my laptop when I noticed that the temps are currently creeping back up under the stress test.

    To start my Max temp was:
    TZS0: 77
    TZS1: 81

    CORE #0: 75
    CORE #1: 75

    GPU CORE:44

    HDD #1: 42
    HDD #2: 43

    I have so far I have seen a reduction to the following:
    TZS0: 69
    TZS1: 73

    CORE #0: 68
    CORE #1: 68

    GPU CORE:37

    HDD #1: 42
    HDD #2: 45

    Now at 1.0875 the temps seem to be climbing back up to this:
    TZS0: 69
    TZS1: 75

    CORE #0: 70
    CORE #1: 70

    GPU CORE:38

    HDD #1: 43
    HDD #2: 45

    Did I hit a ceiling? Or am I running the test too closely together? I am doing this on my Gateway fx p173x w/a T7500 cpu.

    Are you asking why in one test your cores are at 68, and the next they're at 70? It will never be exactly the same every time you test it. 2 degrees seems to be small enough to fall within that range of variance. Its still good, you're 5-7 degrees lower

    It just seemed weird to me that as I was decreasing the voltage the temps started to rise. Should I change it back to the voltage that gave me the lower temp?

    What are you stress testing with? Intel Burn Test will get things pretty hot but hotter then usual. If you use that run it at the standard 5 times and record the temperature it hit maximum.

    If your undervolting with cpu genie the test is better for finding issue with the voltage then it is for temperature testing.

    Also for better accuracy as far as the real temp make sure whatever your checking temps with has been adjusted to the cpu. CPUID HWmon is alot of times wrong edit the ini file with the tjmax of your cpu.

    I am using the battery of tests in the Undervolting Sticky on this site...Orthos, Cupid and RightMark

    Dunno what to tell you then. I used RMClock until i switched to a cpu with a half multiplier, the actual undervolting app doesnt matter. As far as testing I always do things my way. I find an app that produces a consistant max temperature and then test it at each voltage.

    Always test in the same room at the same temp and make sure the surroundings of the laptop havent changed to prevent air flow differences. Allow sufficient time for the processor to return to idle temperatures before the next run to allow for more consistant results.
