Temp readings and G0 steppings

[Vertigo]

Can we try to sort this out once and for all as it's bugging me.

Can any temp readings be trusted on G0 processors? Coretemp is reading well below what it should be IMO, idling at or below room temperature which is obviously impossible. It's been speculated that it's underreading to the tune of 15C but this hasn't been confirmed.

My E6850 is currently running at 48C under load at 3.6Ghz/1.37v according to Coretemp which would mean it's actually running at 63C if the 15C error is to be believed - seems rather hot to me?

Does anyone know a guaranteed way to get the correct temperatures from one of these things as it's driving me nuts - can't overclock with confidence if you don't know how hot the damn thing is

CoreTemp V0.95 or TAT are generally considered to be the most reliable. V0.94 of CoreTemp used to under read by 15c on some later chips, including the G0's I presume, but this was supposedly fixed with V0.95.

What version ae you using by the way?

Apart from that, I'm not sure where you go really. Temp sensors will only give you a surface temp reading, and the sensor within the chip can only currently be read by CoreTemp or TAT.

I think you need to understand, and I've read your other posts, that 63c load for a highly clocked Core2 CPU is nothing.

The more I read about reported temps on here and elsewhere, the more I believe the correct load range for these chips is in the region of 55 to 70c.

I've been trying to cool CPU's in various guises for years, as most people on here have too I'm sure, and I've never got lower than 9 to 10c above ambient temperature, on air or watercooling.

The problem I think is that we all read about other peoples low temps which get us questionning why ours are so much higher. These low temps in my opinion, often at or below ambient temp, are simply impossible under the laws of thermodynamics using air or water cooling alone. It's my view that they are either plain untruths, or inaccurate readings.

I stopped chasing other peoples temps years ago.

The temps reported on an average computer system using the available methods are not even all that accurate relative to your own system, never mind anybody elses!!

I think your temps are being reported about as accurately as they can be, so I'd stop worrying and just get on and enjoy the thing!!

Using CoreTemp 0.95 and it's still under-reading

Using CoreTemp 0.95 and it's still under-reading

In the settings, switch it to delta temperatures. It will then give you the distance from the factory set thermal throttling point.

The reason, not one of the programs can give you an accurate temperature. For instance, the only signal from the quads is the DTS delta value. Every program out there has to assume a throttling temperature to subtract this from, trouble is no one knows the true value for each chip. A thermocouple is the only real value you'll ever get.
