    I recently looked at Core Temp Beta 0.9.0.91 and found my 3800 X2 2nd core runs a minimum of 6 degrees hotter that my core1 temp. This is when its cool’n’quieted down 1 GHz, when it’s at normal clock (2 GHZ) core2 roughly is about 9 degrees hotter, and then another minimum of 6 when on full load.

    Avg. cool’n’quiet temp at same interval
    Core1: 30
    Core2: 36

    Avg. normal temp at same interval (2 GHZ idle)
    Core1: 31.5
    Core2: 40

    Avg. load temp at same interval
    Core1: 40
    Core2: 46

    I’m using an Arctic Cooling Freezer 64 Pro with good airflow through the case.

    I’ve seen a lot of different results out their but what do you guys get? Is my dual core strange?

    my x2 3800 is around the same difference between cores at load as idle, idling at the moment:

    core 1 - 23
    core 2 - 27

    load is around

    core 1 - 32
    core 2 - 35

    Is it always core 2 thats warmer on yours and anyone else that is looking at this?

    Is their a nice sweet thread somewhere that ive missed or can anyone explain why core 2 seems to be hotter, must be how amd designed it.

    I think my Core Temp just broke as well, "Core 1: 54, Core 2: -49".

    CPU Burn got my x2 3800 @ 2500mhz 1.4v to 55oC on both cores :eek: . I voted 1 degree though because one would be 54 for a while while the other was 55 and then they'd alternate with them both occasionally at 55oC.

    It went up to the next degree first usually but it stayed pretty average. There is more difference though as it cools down. First core cools much quicker. Like 2-3 degree difference as it's dropping.

    Id be inclined to think bad contact with difference like that.

    i,m thinking that as well and may opull her down and try a few the=ings to even it out
    might be part of the reason for my cpu 1 going by by before 0

    Ambient about 20c according to the wall thermometer thingy,

    The opty 170 @ 2600 1.4v runnning idle according to Core Temp Beta 0.9.0.91

    core1 23c
    core2 31c

    The Asus pc probe utility reports only one cpu temp and that says 27c.

    I've reseated the Swifty Storm G4 i have and re-applied as5 after cleaning the thing off completely, made sure it's contacted the entire IHS so i doubt there is anything wrong with the cooling TBH.

    It's more likely the core itself not making even contact with the IHS rather than the IHS making even contact with the heatsink/waterblock

    Bit of a trend going on here, looks like 5 degrees is more than normal and core 2 seems to be the one getting the hottest on almost everyones setup.

    Can anyone shed any light as to why there is a difference and why core 2 seems to be the hotter of the 2?

    I just cant understand why the design of the chip would have an effect on the temp difference between cores.

    I might have to post the same poll in the Intel thread and see what they get.

    Thats pretty much the conclusion i have come to as well. I am loathed to take the IHS thing off and sort it out tho, doesn't seem to affect the running of it @2.6ghz under load anyway, stable as a place with horses in it, i.e. stable.

    Full load temps are 8-9c higher than idle so i'm happy enough with temps, just be useful to get them the same for possibly pushing it to 2.8ghz.

    I only get a 1 degree difference on load and no difference for me. I would be worried if there was a major difference between them. Maybe its to do with the overclocking.

    who here uses s&m to burn in/test?

    i have only now just come accross it after reading a cooler review and i have to say it is the most evil viscous program bar none :)

    on full load it actually got my cores over 50 to around 54/55 but the difference then wa only a degree
    using prime etc it was a good 5 degrees less and had the difference of 5 degrees between cores.

    give it a try but be warned by stress testing they really mean it :)

    Anyone got this problem as bad as me? (cpu 4200 x2)
    Using core temp idle temps are shown as core 1: 29C core 2: 22C.
    This is at stock, everything set to auto. The mobo undervolts so it's only 1.31v too.
    When I overclock/volt I need 1.4v to run at 2.4ghz, when running two instances of prime at those values, core 1 is about 60C and core 2 about 49C :confused:
    The bios and other temp reading software all only show one value for core temp, and they all show the lower temp that core 2 is reading in the core temp program.
    Is this core 1 temp reading false? can I set up any other software to read this sensor to prove the cores are that different?
    HSF has been on and off a dozen times BTW, checking and rechecking.
