How to improve Temps Measures Accuracy

Hi All,

I have heard that the temps measures (cpu,mb) of the Asus A7V133 mb
<b>arent accuracy.</b>

<i>note:
i think this is the case with a lot of mb because they have the same measure mechanism which is a thermistor placed near the cpu Core. i know also that last cpu (eg AMD XP) come with an integrated thermistor but this is another history...</i>

I think this is true but what is the error margin ?

<b>Because it's important for overclocking, we need accurate temps.</b> :eek:

So how can we correct this problem to have exact temps ?
Maybe we have to modify physically the mb or we have to put some special temp add-ons on it...
is it possible ?, what are they ?, how can we mod the mb for ?, i dont know...


Thanks all for some knowledge about.

  1. Labdog I use a temp probe that I have placed between the hsf and wafer placed next to the core. (not touching the core)
    On my ASUS A7V266-E the BIOS and MB monitor shows @6c higher than the probe. On my ASUS CUSL2-C the BIOS, MB monitor
    and probe temps are all identical.

  2. thanks.
    but i saw its accuracy is 1°C
    & i don't think you can measure precisely the cpu Core with ?

  3. there is a pb with this reseller.
    i has tried to buy one but he wouldn't accept international order.

  8. thanks. it's also my opinion after have read this article.

    there is just something odd because it has an <b>1°C accuracy</b> but a <b>0.1°C to 0.3°C resolution</b>.

    You don't think it's a little strange ?
