RealTemp General Discussion

[pipels]

Hi unclewebb, I have some troubles with my Q9550 C1.

Recently purchased Q9550 C1 SLAWQ, install the proccessor and the BIOS detect without problems.

My main doubt is about DTS sensors of this quad.

SPECS:
- Q9550 C1 @2,83 Ghz w/ Xygmatek 1283 cooler
- ASUS P5Q-E BIOS 2101
- 2*2 GSKill DDR2 1100
- Seagate 500 S-ATA II
- GTX260 896 mb
- SL-8600-EPS

Actual temps, tº ambient ~ 15º/18º, all values stock in BIOS. BIOS report CPU Temperature 26º.

I get as results high IDLE temperatures...suppose...
What is the error? Are normal temps?
Touch the heatsink and feels quite cold....I don´t understand...

If I ocing at 3,6 ghz show this RealTemp:

DTS sensors don't lie. At least not in full-load when approaching to TJMax.
In idle they are off (at least for 45nm CPU's) but in full-load they became more accurate.
Unfortunately HDT heatsinks are not very good with quads and serios OC (i.e. higher frequencies and Vcore). How do you apply your thermal paste? For HDT's is a little bit tricky.
Also I strongly recommend a bolt-thru mounting kit because I really hate push-pins. Xigmatek Crossbow for example.

Thanxs for reply.

I called Intel support and they told me the temperature are normals because the CPU is 25º/26º jaja!! I don´t believed, for them doesn´t matter the temperature of each every core.

About the Xygmatek, I don´t use the push-pin system, I made a backplate and use MX-2.

Regards.

25C is well within the normal operating temperature of the CPU. why would intel care? it could idle at 60C and it would be stable, so no big deal.

 

[unclewebb]

As Mussels says, as long as your computer is stable then there is no need to be concerned about your temperature readings. These sensors are designed to control thermal throttling and nothing else. Intel doesn't care if they are not accurate enough to report idle temperatures or load temperatures. As long as they are good enough to tell your CPU to start thermal throttling somewhere around 100C and are good enough to tell your CPU to do a thermal shutdown when your core temperature is somewhere around 125C then they are doing what they were designed to do.

Any functionality beyond this is optional and not guaranteed by Intel.

Having some problems.

I just installed this program on my computer, because I am getting some serious slow down issues in games and opening applications. I really don't know how to read it, so here is a picture of my stuff. Also, what the hell does LOG mean for thermal status.

 

[unclewebb]

When I don't understand something, I start by reading the documentation:

Thermal Status

This feature reads information directly from the processor which tells you whether the processor has reached its maximum safe temperature. Intel refers to this as PROCHOT# or processor hot. If your processor has reached its maximum temperature on any core it will display LOG to indicate that a thermal throttling episode has been logged. If it displays HOT in red then that indicates that a thermal throttling is presently occuring. The LOG will return to OK the next time you reboot your computer.

Your CPU cooler is likely not properly attached. That's what the hell is probably going on.

Your computer is thermal throttling which means the multiplier is dropping down to 6.0 so your computer is slowing down when loaded and running like a slug.

There's an About... box in RealTemp that will take you to the main RealTemp web page here on TechPowerUp and from there you can scroll down and find the directions.

 

[kellman]

That is what I was thinking, thank you very much. I was searching for a detail listed of the problems that might occur, but I couldn't find any . Google, Thermal status LOG just was not happening. Anyways, thank you again, I bought some coolant, working like a charm.

 

[Mussels]

yeah its definately overheating, idling at 81C. your cooler is either not attached properly, the fan is not spinning, or the thermal grease has been removed.

Calibrating I think

Hi All, (first time post)

I've read the calibration docs page and back to about page 12 of these boards. I don't feel like I did this properly.

1) Carried machine to basement and removed side panel.
2) Verified EIST and C1E in BIOS, set bios vcore to 1.10; however CPU-Z always shows 1.072
3) Used Fluke 62 IR "gun" to shoot various spots in case. This is where I felt lost. The temps were all over the map. I seem to recall shooting upwind of the heatsink. I found a power cable sitting close by and shot that as well as the lower tins (closest to cpu). With little confidence I announce my tins/case temp to be ~30C. The rug in front of case was 24 or 26.
4) Ran the sensor test and low and behold it looks like I have a stuck sensor.

I'm not sure what my next step is? .INI mods?

 

[burebista]

Bad luck. Core0 sensor is stuck. Nothing to do.
Try LinX (with All memory option) to heat-up your cores and see if it moves past 40C.

Why LinX? Does it cause heat differently then Ortheos, Prime95, etc? I'm running Prime95 right now and Core 0 is reading current temp of 51 at 96% load.

 

[unclewebb]

burebista is right, there's nothing you can do with a stuck sensor except ignore it in the range that it is stuck which is any temperature below 40C. When the core temperature goes over 40C, it should start working OK.

Core 1 probably reads a little too high. If you want to try and correct for that you could use a calibration factor of -2.5 or you could just leave it as is and not worry too much about temperatures. As long as your computer is stable, core temperatures aren't too important.

LinX tends to create higher temperature numbers than Prime95. Core 0 is moving now so no need to run LinX.

 

[Homeless]

Linpack will increase the temp of your processor significantly compared to prime

 

[jmairs]

Core 1 probably reads a little too high. If you want to try and correct for that you could use a calibration factor of -2.5

Under Settings->Idle Calibration -2.5 in the 2nd block right?

 

[unclewebb]

That's right. It goes Core 0, Core 1 from left to right so to adjust Core 1 you would use the 2nd block.

At higher temperatures running Prime95 Small FFTs, how do the two core temperatures line up? That is my favorite test for creating an equal load on each core. At full load, in theory, the temperatures should be identical on a Dual Core. My E8400 is one of the lucky ones where this is actually true.

 

[jmairs]

At higher temperatures running Prime95 Small FFTs, how do the two core temperatures line up?

Core 2 is still running about 2 degrees warmer. Occasionally flickers to 1 degree difference. Been running prime for 12 minutes now.

 

[Dreadnought33]

Hi uncleweb. Does Real Temp need to be calibrated to read properly Core i7 internal diodes?? If so what should be the delta between the cores and the CPU heatsink?? I have an infrared thermometer and was planning to calibrate reading the CPU's heatsink base temperature. Do I make any sense??

 

[unclewebb]

Dreadnought33: The Core i7 sensors are much more accurate with a lot less issues than the previous Core 2 Dual and Quad sensors. Most users don't bother doing any calibrating of their Core i7 CPUs. I sent you a PM with some of the minor issues that these newer sensors have.

Test interpretation

Hi All!

I have just bought an intel quad 8200 cpu, and installed it.
However I seem to be getting quite hight temperatures, but I don't seem to know why.
I think I installed the heatsink ok. Even changed to another thermal paste from the factory original, but still the same
I ran the cooldown test, and got the following.
Could someone help me interpret it?

 

[unclewebb]

The Intel OEM cooler is a barely adequate cooling solution. It's small and light which allowed Intel to reduce costs by being able to ship it in a smaller box. Beyond that, if you intend to do any overclocking then I would recommend a good after market air cooler.

Did you have any problems getting all 4 push pins to go through the board? With the OEM cooler I prefer mounting them outside the case so I can flip the motheboard over and be 100% sure that it has been fully seated.

If that is OK, the only other thing that you need to check is core voltage. Run a program like CPU-Z. What does it report at full load for core voltage as well as core voltage at idle? Too much voltage can lead to higher than normal temperatures. Is your CPU case open or closed? It's summer time where I live which can also create a lot of extra heat.

 

[d1289]

Thanks.
I think I will take your advice, and buy a new cooler.
I thought about the Arctic Cooling Freezer 7 PRO (I'm no hardcore overclocker, so I thought it would suffice). Is it any good?
CPU-Z reports 1.216V core voltage for for idle and 1.2V (although it did went down to 1.192V for a few seconds) for 100% load.
The computer case is closed.
It's summer time here too, but 87 C is still too high for my taste.
Could it be that the TJMax isn't 100C for all my cores?
Thanks in advance.

 

[unclewebb]

Could it be that the TJMax isn't 100C for all my cores?

It certainly could. TJMax is poorly documented by Intel including the amount of error. In 45 Core 2 Quads it is at least +/- 5C and could be as high as +/- 10C. Intel is not willing to say probably because it doesn't look too good when a high tech company uses low tech temperature monitoring sensors. These sensors were only designed to control thermal throttling and for that purpose they work 100% but when we try to use them to provide us with accurate core temperatures, they're not so good.

Pretty much any after market cooler will get your temps lower. The Arctic Cooling Freezer 7 PRO is a good choice for your application. It's not too expensive and it works.

 

[d1289]

Thanks, than I will proceed with buying that cooler.
One last thing:
Base on my previous posts, could you tell me whether I should change the TJMax for any of the cores (or change the idle calibration) to get accurate results?
Thanks in advance.

 

[unclewebb]

Post another cool down test when you get your new cooler installed. Hopefully I will have some time then to have a good look at your calibration settings. We might also need to do a few more tests at idle.
