Real Temp Question

I recently posted a question about what are safe temps for Core i-7 940 2.93ghz. I posted that I had overclocked to 3.42ghz with no voltage change. I then downloaded realtemp 3.00 and ran Prime 95 for 1 hour. The highest temps in real temp read: 52 52 49 50. I understand that aspect, but what the hell is "distance to TJ Max"?????? I also noticed that my Asus Probe stated the cpu temp was 58c under full load and realtemp stated my cpu was at 52C under fulload. I take it to trust realtemp instead fo the Asus probe software?

Thanks...here are my comp psecs:

Thermaltake Spedo Advance Tower
Asus PT6 Mobo
Intel Core i-7 940 OC'd @ 3.4ghz
V8 Cooler Master CPU Cooler
6GB Kingston HyperX Memory
2 X 500GB Seagate Barracuda's in Raid 0
Sapphire Radeon 4870 X2 2GB Oc'd 785/975
1200W Thermaltake PSU
SB Xtreme Gamer X-FI Sound Card
Creative SB 7.1 Surround Speaker System

If you had taken the time to read the Rel Temp Documentation and read the Temperature Guide which I linked for you in your previous thread, then this thread wouldn't be necessary.

Your nerdy guide n the 1st thread didnt answer my question above. The techpower up link was not provided the first time to me. You could be more helpful not giving attitude over the thread. But then again reading your guide its apparent you have no social life. I guess a typical response from the typical anti-social geek.

First we must look at the scope of his guide.

Scope:

This Guide is intended for intermediate to advanced users Although certain strict definitions have been relaxed to simplify concepts, this Guide contains detailed technical information. Knowledge of hardware configurations, BIOS menus, motherboard manuals and terminology is required, as well as familiarity with CPU-Z, Prime95 and SpeedFan.
Apparently you are neither and yet you blame him because his guide is too complicated for you to understand? An alternative would be to post same, and he would be back here holding your hand.

Toward the bottom of his guide he linked the HOWTO: Overclock C2Q (Quads) and C2D (Duals) - Guide v1.6.1. In this guide you will find the following:

The formula for reading core temp from the DTS (digital thermal diode) is:
  1. Core Temp = tjmax – DTS
  2. Where DTS is the number the DTS is reporting, and tjmax is a constant (which differs with processor model and sometimes within a processor model based on its stepping)


Note: There is no official communication from Intel as to the magnitude of tjmax for desktop/server C2D/C2Q chips! This makes calculating the “real” core temp tough since people are just guessing.

For example, a Q6600 (G0) stepping may have a tjmax of either 95 or 105 (again, these are people’s best guesses). If tjmax is 105, then Core Temp = 105 - DTS. THIS DOESN'T MEAN THAT THE LIMIT FOR THE CHIP IS 105 °C! In this example, let’s say the DTS value is 50. Therefore, Coretemp = 105-50 = 55 °C. If tjmax is 95, the math becomes 95-50 = 45 °C. Don’t worry about doing this calculation; all the temp monitoring software will do it for you. I only mention it so you can understand what’s going on.
Clearly, the information in question regarding the DTS and distance to tjmax was accessible from his guide. The specific data relating to the Intel "released" Tjmax numbers is a little dated, but it's well covered in Comps guide so that's not really a problem. The passage is there to give an understanding of the process.

I was going to just Google it for you, but that would be too easy.

+1 for Comp and Zorg.

@OP: If you just googled....

]Googled

The first link (anandtech) would have given you the answer.

It is and it isn't. Intel has given us some numbers and said Tj Max could be higher by X amount (literally just X) for any core but that's about it. Nothing concrete, just something to chew on.

Well Intel did give some guidance on the chips, not concrete guidance but close. There was a question about the Q6600 being 95c or 100C. Core Temp had it at 100C and Real Temp had it at 95C. Based on the last round with Intel, everyone agrees it's 100C. (actually closer to 97C ;)  ). The numbers he is throwing around appear to be a little dated, but again it's not a temp guide, that's why we have Comps.

Although some will actually appear to be 105c for two of the cores :)  Aren't temps fun! :pt1cable:

I have to agree that temps are fun.

I have a much the same setup, exept for a few things: I have a core i7 920 in an asus p6t mobo, but I have a TRUE to cool it with the push/pull configuration. I use speed fan and the pc probe II that comes with the modo. I get ~25C on idle and ~45C on load for both proggies loading it up with prime 95. I'm sure if I overclocked it to 3.4ghz it would get the same temps as you, so I would download speed fan, and which ever proggie it's closest to, go with that one. Also what is your bois temps? Mine are about 5C to hot so you can also see which proggie is ~5C away from that.

Don't forget that ambient temps play a huge role in core temperature.
