Real Temp - New temp program for Intel Core processors

[randomizer]

i will wait for the intel next update & your opinion

The next Intel "update"... I wonder when that will be. Most of the lustre of their "updates" has been lost since the last two IDFs.

[concretefire]

hey, unclewebb. Couple questions.

I'm using v 2.84 for my Quad 6600. Is there any need for me to upgrade to latest version?
Lately my temps in 2.84 are jumping. Like every second, litteraly. It goes from 57 to 66, like clockwork every single second. 57,66,57,66,57,66 etc..etc..

I've been tweaking my system. Surely this is the result of something I have done???? OR, realtemp is correct and I'm spiking.

[ericjia]

Thanks unclewebb for your detailed information.
I am not familiar with low MHz test, but will learn and find time to give a try.

[unclewebb]

concretefire: I like the improved CPU Cool Down Test in the latest version as well as two lines of information at the top that includes CPU Load. It's been more thumbs up than thumbs down recently so I think you should give it a try and decide for yourself.

http://www.fileden.com/files/2008/3/...alTempBeta.zip

The CPU Load display in RealTemp 2.90 is very accurate and repeatable. Just running Task Manager on my system creates 0.5% load and increasing the refresh rate doubles that. I never knew useless information like that until I used the new RT Load feature.

It might help you find out if you have any software running in the background causing your jumping temperatures. The sensors rarely jump around unless the load is changing. Disable useless background tasks until you get your Load down to 0.0% and then have a look to see how stable your temps are.

ericjia: I'd be very interested in what temperature your CPU idles at when at low core voltage and low MHz. That's what C1E is designed to do to save power but I found that doing this manually gives you a good baseline which you can compare to others. A wide variety of CPUs don't vary too much during this test. Plus or minus 1C covers the majority of Intel Core processors. Let me know when you have the time if you need any help or suggestions.

Sorry for the delay in getting some results posted. Haven't really had a chance to overclock my Q9450 until yesterday.

By the end of the day I was able to get to 8 x 425 Linpack stable (I know this doesn't mean it's completely stable but it gives me a baseline for fine-tuning later).

What I can tell you is that now that I've overclocked it some and I'm pushing about 1.35 volts (trying for 8 x 450) through vcc with LLC, the temps have increased and are now looking MUCH closer to each other - 5-7 degrees of each other. I'm sure some calibration is still needed, but it looks like what you had assumed earlier holds true.

Hopefully I'll be able to post screenshots of Real Temp cool down test by the end of this week with my final overclock.

Excellent program as I can tell thus far.

Damn me and my eternal search for ET. (Seti @ home)

Hey unclewebb....in no way did I mean for that question to come across as a problem or glitch with your temp program. I already knew the answer, and you were correct. I have no explanation for even asking about it other than the fact that I am a dumbass.

My Real question was would I benefit, or should I upgrade versions. I have been reading how you've been working on i7 alot, and somehow got it thru my head that the latest and greatest might not be ideal for my "old" Q6600.

In hindsight, another boneheaded question.
Think I'll stop posting for a while.

[HuffPCair]

I was going to say because I have my Q66 and my temps are nice and low in the upper twenties and when idle only move maybe one or two degrees. I love this program keep up the good work UncleWebb

[unclewebb]

No problems concretefire. I get a little carried away sometimes trying to make sure everyone is getting some decent temperature numbers out of these crappy sensors.

There have been a lot of tweaks to RT for better Core i7 support but I also added some features to keep the rest of us happy that can't afford or aren't interested in an advanced 8 threaded heater. Nice in the winter but I can just imagine the complaints next July. Time to invest in water cooling companies. Every Core i7 owner will be getting one next summer.

[rge]

No kidding about these i7's being heaters. I had to adjust the heating vents in my entertainment room, b/c my computer is raising the temp 2-3C in this room over the rest of house when running prime overnight.

My core i7 is even taxing my water cooling, I cant imagine it on air. I have a cpu only loop, PA120.3, 3 yates 1300 rpms, swiftech GTZ 1366, and my load temps are 73C with 1.35 vcore bios, 1.31v load for 4ghz stable (4.2 turbo). But all the new bioses with turbo enabled are set such that turbo is active on all 4 cores (instead of being TDP/2core limited on F3 bios), so have to find new settings for new bioses. Ambient is 26C.

4.2 ghz w/ 1.41 bios, 1.36 cpuz ran prime 4 hours before rebooting but load temps were 82C. I am just not into 80+ load temps especially on water.

Now trying for 4.14 (23x180) w/ 1.381 in bios, 1.34 load, temps are 76-77C on load, though apparently bounced up to 79 on core 0 once.

Not using faster fans as I like quiet. If next year the leakage or TDP does not go down on newer ones, I may be using dual rads just for cpu. Intel needs to get a better handle on leakage before going 8 core/16 thread.

BTW...loving the new realtemp layout. mhz total and w/multi*bclk, load %, and timer all with easy glance, perfect for ocing. The only thing I need cpuz for is check vcore. Not to mention max temps recorded which are very helpful for o/n runs on these.

[xarot]

WTF is going on? My QX6800 cores heat up like this:
30-27-62-31 degrees? Is the processor heatspreader twisted or what? The "test sensors" gives like 6 sensor movements for that one core, the others are 14-15. Is the sensor malfunctioning? I've tried different air coolers and that didn't help

[unclewebb]

I like quiet air cooling so Core i7 in its present form is not for me. Maybe when they shrink the process down to 32nm next year or bring out a Dual Core version, I'll think about it. I'm kind of spoiled by the cool and quiet performance you can get out of an E8400.

xarot: Sounds like you've got a stuck sensor. Intel says these sensors are not designed to be accurate at lower temperatures and will become saturated as the CPU temperature drops. That's a fancy way to say that some of them stick and stop moving as the CPU cools down. They were designed to trigger thermal throttling and thermal shut down and even sticking sensors don't seem to have a problem with that when the CPU temperature goes higher.

Post a screen shot of the CPU Cool Down Test. It's an excellent tool for spotting stuck sensors and should show you exactly what's going on.

Hi, thanks for help.

Here's a quick test:

Not any of the sensors are totally stuck, or what do you think? The temps can't be right anyway? I just got this chip from EBay as a new one and I'm worrying do I have any overclocking chances if one of the cores is reporting crazy temps at default clocks.

I swapped the mobo for this test..now running on DFI X48 and Noctua NH-U12P. The previous test I did was with QX9650 stock cooler running at max speed.

[unclewebb]

Your Core 2 sensor is not the typical stuck sensor and it's definitely not working right. It's possible that you'll still be able to get a decent overclock out of this chip but the Core 2 sensor is likely going to be the first core to signal thermal throttling. When this happens the multiplier is going to drop down to 6.0 and is going to kill performance. On the main RealTemp screen keep an eye on the Thermal Status area where it presently says OK. If this ever changes to LOG then that means that Core 2 has logged a thermal throttling episode. If it shows HOT then that means that thermal throttling is in progress.

Overclock as much as you can. Thermal throttling usually occurs at about 98C. The slope of this sensor is very slow. Your other CPU cores might be able to get 20C or 30C hotter and this sensor might still not move enough to trigger thermal throttling. Let's see some numbers out of this QX6800.

[zillaoc]

Great app. TY unclewebb...

[Venturer]

To unclewebb:

First thank you for this great and wonderful program. Now the question: What do you think about a QX6800 TJMAX stepping B3? Is it 85c or 100c as many say? Coretemp reports temps 20c higher than realtemp.

Realtemp 2.90 says my qx6800 idles at 55/53c for all cores at an ambient temperature of 22.5c. When i play games like call of duty world at war; after half and hour realtemp shows "log" in thermal status. I have a good aftermarket heatsink...a 2pcom 92mm heatsink with htc (heatpipes direct touch). Also i'm using zalman stg1 thermal grease. What's wrong with my temps? My motherboard is an Intel Bad Axe 2; i have read this motherboard reports temp 20c higher than normal. Is it true? I believed dts sensor are indipendent from bios readings.

Thank you!

[burebista]

You have a problem with your heatsink, DTS readings don't lie. At least not then they're close to throttle point.
This is your cooler? If yes take a look at your push-pins, maybe one/two were out.
IMO HDT (and with 4 pipes instead of 3) on an 130W Quad is not a very good cooling solution.

[unclewebb]

Just a few minor tweaks. The CPU Load has been adjusted to reduce rounding errors. The XS Bench got changed slightly. The score should be the same but the time will be slightly different.

Venturer: I think RealTemp defaults to TjMax = 90C for a QX6800 - B3.

There will be endless arguments about "What is TJMax" because TJMax is not a fixed value. It varies by a few degrees and Intel has not told the user community how much variation there is. 90C might work well for your QX6800 and 95C might be more accurate for your neighbor's QX6800.

Post a screen shot of a CPU Cool Down Test if you can along with the main RealTemp window.

TJMax isn't that important. What is important is the LOG showing up in RealTemp. That means that your processor has been thermal throttling and that means it was slowing down during your game because it was getting too hot.

Post a CPU-Z screen shot as well. Your core voltage might be too high.

The B3 Quads have a reputation for hitting the thermal throttle fairly easily. That's why Intel raised TJMax for the G0 series.

burebista's theory of a loose heatsink is very likely.

[Leeghoofd]

Unclewebb can you have a look at this plz :

TEMP/VID ANOMALY AFTER BIOS REFLASH

[Venturer]

First of all, thanks for your advices guys!

Here we go; here's the screenshot.


So....
i have lowered the multiplier to 8x for a 2133mhz max working speed, because i'm very scared of blowing all. At 2.93ghz full qx6800 speed it reaches 90c but the system stays on....

@burebista
yes my heatsink belong to this brand but is the smaller one model; the one with 92mm fan and not 120mm fan you linked; they are absolutely the same apart the dimensions....

I have a silentmaxx ST-11 big tower case and unluckly i can't mount tower heatsinks bigger than ones with 92mm fan; 120mm fan tower heatsinks are too tall for my case.
Burebista in your opinion what is the best cooler for my case and my CPU (brand and model please)? I remember you i can mount 120mm fan cooler that mounts "flat orizontally"....or obviously tower heatsinks with max 92mm fan.

Thank you soooo much guys!

Edit: Another important note - Temperature grows up very much when i play games because i have a crossfire ATI 3870x2 + 3870 configuration. I think during games the case air temp is much hotter than when i run prime95 because of the gPUs at full speed......i'm still talking about the qx6800 setted at 2133mhz.

[unclewebb]

Leeghoofd: I posted an answer on the other thread you started. I don't have much for a reasonable explanation of what you're seeing.

Venturer: I'll have a better look at your numbers tomorrow. Duty calls.

[burebista]

Sensor movement looks OK, CPU Coold Down test looks OK, so you don't have stuck sensors.
Not OK are temps. Vcore is reasonable but distance to TJMax in full-load is too close to throttle point (at least for my taste).
First try to reseat your cooler. I'm almost sure that one/two push-pins were loose or you put too much Zalman grease (here are some pictures with HDT spreading grease technique). Even an HDT cooler should keep your Quad colder in full-load at stock speeds/voltage.
As for a new cooler TR SI-128 SE or TR Ultima 90. Both are mounting with backplate. Another choice Scythe Andy Samurai Master and Stabilizer 775. My idea is to get rid off those push-pins.

BTW that's why I somehow dislike HDT heatsinks with 4 pipes



That photo is from Sunbeam Core Contact Freezer. He managed to keep a Q6600 @3.7 GHz VCore 1.520V at 78°C in prime95 small FTTs. As you see 2 heatpipes barely make contact with IHS.

LE: Frankly for your setup I strongly suggest a new case with decent space and airflow.

[Venturer]

Here is the cooldown test with the case lateral cover open:


Notice the lowest temperature is 34celsius.

burbeista so do you think is an heatsink problem or a case airflow problem?

I would buy a Ultima 90 cooler but do you think there will be an improvement with case closed?

Thank you!

[burebista]

It's obvious that it's a big improvement with case open. You gain 18°C.
Can you post a photo with your setup? I want to see what's happening there. Now it looks like an airflow problem.

[unclewebb]

Your cool down results look very unusual. My first question is how much stuff do you have running in the background on your computer when you're testing?

If you go back a page, here's an example:

http://www.xtremesystems.org/forums/...postcount=2808

After Prime95 is finished running, his computer is showing 0.2% for Load which is typical while yours is showing 7.6%. I also can't understand what's going on at full load. Normally the load steps down significantly after a couple of steps while yours is still running at close to 100%. The third step should be somewhere around 77% while yours is at 97.8%.

Your sensors seem similar to randomizer where maybe they read high from idle to TJMax. To start trying to figure out what's going on, open Task Manager and find out what's running, open your case to get the heat out of it. Laying your computer on its side so the hot air from you graphics cards can go up isn't such a bad idea. What's your room temperature? How much thermal paste do you use and what's your method of applying it? I think you have a combination of problems so you're going to have to look at some of the basics first.

Edit: In your second test your computer is showing 9.6% load when it should be idle. Kill some processes that are causing this.

[Venturer]

Here's the photo of my case open; notice the back of the case is near the wall of my bedroom under my private desk.

And here is the screenshot of the active system processes.


So what's my problem? Should i change the heatsink?

Thank you sooo much again guys!
