Xtreme Low Q6600 G0 Temp on Air !!! (Lots of Pics)

Just use Coretemp 95 track your delta to Tjunction and check for stability. The larger the delta, the more headroom you may have with overclocking?

That's exactly what I found when playing around with my E6400. As the MHz went up I needed to leave more temperature head room to maintain long term, 100% Orthos stability.

Here are my approximate findings:

3200 MHz ~ DTS=5
3400 MHz ~ DTS=15
3600 MHz ~ DTS=25

Intel uses readings from the DTS to control the thermal throttling point as well as the THERMTRIP# processor shut down point. Stability when overclocking is also directly effected by how much head room the DTS is reporting so it's a good idea to forget about absolute temperatures and concentrate on how much head room you need to remain stable.

If you're not stable then you need to back off your overclock and that's about all there is to it. The engineers have built in a huge amount of temperature head room into the Core based processors and these processors are better equipped than any before to take care of themselves if they get too hot.

I have thoroughly tested CoreTemp 0.95 and it reads and reports the DTS 100% accurately in real time and is the only program I know of that reports the DTS value directly. SpeedFan 4.32 also reads the on chip DTS correctly but with the Q6600 it seems to be using a TjMax=85C instead of TjMax=100C so its absolute temperature readings need to be corrected by 15C as I previously posted in #269.

I wouldn't trust any other temperature information or software unless someone has taken the time and thoroughly tested it by reading process register 0x19C using CrystalCPUID or similar utility. CoreTemp passes this test. Many other programs, including TAT, do not.
