Did this ever happen? It's past October 21 but a quick google didn't turn up anything.

Thanks, that's informative and helpful. I understand your points on the calibration of the thermometer, the place I ordered it from could offer a calibration certificate, but it cost more than the unit itself! I tried your test with a fever thermometer though, and they both displayed within a couple...

Hi fgw, thanks for your reply, you make some interesting points, at least one of which I'm not sure I understand, but we'll get to that later. Its probably easier and clearer if I reply to the issues in your post in the same order you mention them. Firstly for the underclocking temp readings I took,...

Ok follow this portion of this guide, somethings not right and this should locate what the problem is, feel free to refer to the whole guide if you wish I have read that guide before, its no further help. I am pretty confident I have located what the problem is - my chip is simply miscalibrated som...

I have gigabyte (lol considering your name) P35C DS3R mobo. Can't find any PECI options in bios which I think is something point nine version, it was flashed to the latest version about a week ago. I posted some screenshots of my temps etc earlier in this thread, but if you want more imageshack does...

Because its not right for M0, hes just going by the majority.. which is every temp monitoring program showing 85c tj max for every CPU except quads, and those who panic that their temps are too high, if people knew how to properly read the temps it would be fine. Things are different from the Netbu...

Ok, but its definitely not right for my cpu, if everyone else's M0's are ok I must have an anomoly.

Agreed, still using 0.96 in preference to 0.96.1.

In my opinion the best way to use this technology is how Intel intended it be used. In Core Temp there's an option to "Show delta to Tj. Max". This shows the actual value of the DTS, and the amount of degrees in C° from the #PROCHOT. The only reason this is not used by default is because...

Yeah, Speedfan 4.34 beta37 and 4.33 give the same readings, I have them running side by side atm. I just wondered if the quoted 100°c Tjunction max was a nominal figure and could be varied somewhat batch to batch as Intel's engineers see fit? They don't seem very forthcoming on information in this ...

If anyone is interested here is a screenshot with my 2140 underclocked to 900mhz and undervolted to 0.9v, at idle, ambient 24°c: http://img301.imageshack.us/img301/2269/ucidlejm1.th.jpg And for reference the same chip overclocked to 3ghz, full load, same ambient: http://img87.imageshack.us/img87/35...

Hi Gigabyte, I crossed posts with you above, I wasn't meaning it to look like I was disagreeing. In fact i agree. I'm led to believe that with sufficient underclock I should be able to get Tcase to very near ambient but Tjunction will always be around 10°c higher. If I use the cpu reading in speedf...

Just double checked my temps at that underclock on an M0 2140.

Coretemp 0.96.1 = 1°c above ambient

Coretemp 0.96 = 16°c above ambient

Thats with ambient measured one inch in front of the cpu fan, all fans on full and the side of the case open.

Hi, as it happens I was doing some underclocking experiments yesterday with an M0 2140 and coretemp 0.96. (ie the 100°c tjmax version). With vcore of 0.9 and clock of 6 x150, cooling at maximum, the chip was idling at 17°c above ambient, as measured by coretemp. Full orthos load only added another...
