Temperature Monitor Alert:Memory controller heatsink Results!!!

Hello all...
I have a question about the Memory Controller Heatsink sensor in the temparature monitor and I would appreciate it if you could shed any light in my problem.
Well it was long time since I checked my temperatures on my G5 DP 2.3 so yesterday while I was into some MP3 encoding I heard the fans making alot of noise ,not something unbearable but not the usual silence behaviour I was used to even under heavy load and with the nap off.
So because of that noise I decide to check it with the temperature monitor but nothing unusual came up except...yes you guess it the Memory Controller heatsink.
An alert came up and inform me that the temp was over 75 C/167 F.
The threshold was by default at 75 C/167 F.
Let me add that it's summer here and a hot one at 37 C and the room is not airconditioning,but it was exactly the same one year ago(June 2005)and I never came up with an alert.
Also I have no problem with the rest indications.
So what do you think is it normal or may I have a broken fan?
And finally what is the Memory Controller Heatsink?
Thanx in advance!

The memory controller heatsink is shown, with the associated cooling tubes and fins, in the right-hand photo of the 'back' of the main logic board here
http://homepage.mac.com/jerrycube/jerrycubepix/22601bluebord.jpg
Air is pulled over the back of the main logic board and through the cooling fins, by the fan in a plastic housing, at 90deg to all the other fans, behind the hard drives.
This fan is called "Main Logic Board Backside" by Hardware Monitor in this ancient DP2.0 - and is showing "20%" in 22deg C room temperature. "Memory Controller Heatsink" is at 54deg C.
37deg C is above the specified max. 'Operating Temperature' of 35deg C shown here
http://support.apple.com/specs/powermac/PowerMac_G5_Late2005.html
I think it would probably be advisable to find some way of lowering the temperature of the room the G5 is in...

Temperature monitoring; best method?

I am having reliability problems with my G5 2.7. I am planning to ask questions soon in the hope I can deal with that.
In order to give the fullest picture, I think I should at least know what the operating temperatures are in the computer.
Please tell me how should I record these, is there a "window" within OS 10.5 to temperatures, or do I need a utility to access and read them.
Is there a standard way to make the computer work hard to reveal any overheating issues which may not be present at idle?
Any other suggestions in this aspect would be welcome.

Thank you Hatter.
I have run tests overnight by doing 6 iterations with Rember on two 1 Gig sticks (tests all passed BTW). I tried Running Photoshop CS4, but even with only 2 Gig of memory on board the computer scarcely broke sweat, only mild temp increases, in comparison with Rember.
In fact the overall temperatures dropped from their overnight rest levels after it had finished the memory test. I think that may be because the fans spun up slightly as I performed tasks in PS like Gaussian blur, Re-sizing, and USM etc. no significant temp rises during any PS activity.
The most significant temperature fluctuation seems to be the Memory Controller Heatsink which peaks at about 106ºC at the start of each of the Rember tests. How significant that is I don't know. Can anybody comment on that figure please?
The Memory Controller Heatsink quickly returns to it's average temperature, fluctuating between roughly 60ºC and 80ºC apparently showing the heat sink is doing it's job. If the heat sink weren't doing it's job I would expect the temp to come down more slowly than it rose. The spikes are same angle up and down.
Currently the Temperatures are:
CPU A Die Temperature Min: 44.8 - Max: 84.3 - Current: 54
CPU B Die Temperature Min: 43.3 - Max: 79.0 - Current: 52
Drive bay Temperature Min: 21.5 - Max: 23.0 - Current: 22
Main Logic board Bacsd Min: 37.5 - Max: 45.2 - Current: 41
Memory Controll Htsnk Min: 62.2 - Max: 106.6 - Current: 65
ProcessorCard A Ambnt Min: 33.2 - Max: 43.2 - Current: 43
ProcessorCard A Ambnt Min: 31.5 - Max: 39.8 - Current: 39
Does anybody feel these temperatures are out of the ball park? They cover the last 11 hours, and include testing my RAM with Rember, which to date has the greatest effect on the temperatures. By comparison looking at the graph now using PS generally brought the temperatures down quite significantly.
I could post an image of the Temp Graph if it were any help. I am not sure how to do that on this board.
I plan to do more tests including with the full 5 Gig of memory installed.
Thank you for your interest and suggestions.

Room Temperature Monitoring

Dear All,
I need to develope a room temperature monitoring system which will alert by send mails when the temperature goes high. I just wanted to know whether there is any such hardware in the market, together with java, I can acheive this. Any help will be greatly appretiated. Thanks in advance. You can also mail me to [email protected] Thanks once again.
Ramya.

ramya1us,
Have a look at http://www.ibutton.com/ibuttons/thermochron.html and at http://ibutton.com.ibuttons/java.html . They seem to sell plenty of hardware and information on writing software to interface with it.
I know of someone who has bought some of their hardrware and created a user controllable WebCam with it.
Hope this helps.

Temperature Monitoring Utilities

Hello,
I just thought that I would share the utilities that I use to monitor my Qosmio's temps.
For CPU I use Intel's XTU (needs to be an Intel CPU) use version 4.0.6.102 - the newer would install >>> https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&ProdId=3483&DwnldID=22485&keyword=%22%22extr...
For GPU I use GPU-Z.
A note about Intel's XTU, I use just the monitoring and information functionality. The monitor will show CPU temps per CPU and Core, it will also indicate if your CPU is throttling due to heat. The utility has option to tune voltages.... LEAVE THIS ALONE! It will warn you if you select it, this is for overclocking and is just stupid to attempt in a laptop.
A note on overclocking, it's stupid.... it will get you a marginally higher benchmark score but not any noticeable difference unless you are really pushing the CPU and cooling with LN and ONLY doing it to post some high benchmark number not use the computer in any usable fashion. A corollary of this is that within a given CPU family there isn't a noticable differnce between the highend part and the lowend. I went from a hexacore i7-3930K with 64GB of RAM to my Qosmio ( I needed portablity ) to my Qosmio x870 --- i7-3630QM with 24GB of RAM with absoulutely no performance difference other then benchmarks and 3DSMax rendering time ( which wasn't in realtime anyway so adding an hour to a render isn't a big deal ).
-J

Using the TOOL, for Monitoring
5 minute Stress Tests RESULTS ARE IN!!!
Impressive after all the BETA testin, 20 months of Gaming and ALL the stress I ask my Qosmio x870 to do, of cause it PASSED both tests!
Standard Running Temp.(Internet, Office, Email) temp was 55 deg C
CPU 100% load (running @ 3.4GHz) temp was between 81 deg C and 84 deg C.
MEMORY (All 32GB of it) temp was between 83 deg C and 88 deg C
The Intel Quad Core i7 3610QM has a rated temperature max of 105 deg Celsius!!!
So I am stoked with the results!!!

(865PE Neo2) - Memory Controller Problems ???

Hi, I've been having problems with my RAM. I've run MEMTEST and found that my RAM continually failed test #5 (64 Block move). However, I pulled the RAM and tested in a friend's computer..... and it passed without any problems..... I went back to my computer and continually changed the BIOS setting until I finally got something to work....
What I did, was change the DRAM Freq from 400 down to 333. And it seems to be stable..... (The RAM was meant to run at 400)
The people at Corsair offered to replace the RAM, however, because both sticks produce them same problem, and because it works at 333 but not 400, and because it fails test #5 and not any other test, then they think the problem lies somewhere other then the RAM. And at the stage, i tend to agree.....
Now someone suggested it might be the Memory Controller..... I have no idea what that means..... but it sounds plausable.... Eitherway, I believe it might have something to do with the Motherboard..... And I was hoping someone here might have an idea on how I can either test it, or fix it.....
Thanks a bunch.....
My SYSTEM Specs are.....
MoBo : MSI 865PE Neo2-P (MS 6728 ver.2)
CPU : Prescott 3.2
RAM : 2x 512 Corsair XMS 3200 (DDR400)

Thanks a lot..... :-)

Hi,
I've tried the RAM sticks individually, as well as 1,3 and 2,4..... And it doesn't make a difference.
I've aslo Disabled Spread Spectrum
And I've also tried all these setting, plus more.... @400Mhz
2-3-3-6
2-3-3-7
2-3-3-8
2.5-3-3-6
2.5-3-3-7
2.5-3-3-8
3-3-3-6
3-3-3-7
3-3-3-8
all without success..... And what i mean, is that I still get error#5 in memtest. And ALWAYS the error occures in the 92%-96% portion of the test.....
HOWEVER, When I drop the DRAM Freq to 333.... No problem..... All is fine..... Even at 2-3-3-6
Unfortunately, I doubt I will be able to test any other DDR400 memory in my system, but it would be interesting to know the results.....
I also find marginal confort knowing this problem is a bit 'common', however, i would find MORE comfort solving the problem :-)
Thanks :-)

Is it possible to transfer the temperature readings through "Serial I/O" port of Lakeshore temperature monitor?

With this monitor, you can have 2 analog outputs that you can transfer to the computer by using DAQ boards. In my case, I need temperature measurements at 3 different locations so I need 3 analog outputs, which is not possible with this device.
However, the monitor can also store temperature data in its memory and print the data. What I need is not to print the data but send the data to the computer somehow in digital form and postprocess it. I am using the "serial I/O" port to connect the device to the computer. I think I can do some configurations on the temperature monitor with the drivers in the link (http://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=0241DD1B3AAF0341E0440003BA7CCD... ) but I am not sure if the device recognize the commands that I send through the I/O port.
Any advice on how to transfer (in digital form) the stored data on the monitor to the computer?

http://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=0241DD1B3AAF0341E0440003BA7CCD...
and the temperature monitor is the one in this link: http://www.lakeshore.com/products/cryogenic-temperature-monitors/model-218/Pages/Overview.aspx
Actually, it says in the manual that the stored data can be send to either printer or they can be retrieved by the computer interface. However, there is not enough information about how to perform this task.
I am using labview to read the data for the analog outputs and the drivers in the first link are also in labview language. But with those drivers, I cannot retrieve the data to the computer.
I will check MAX to test the communication with the device, though. Thanks for the advice!

Operations Manager - KMS Idle Minutes Monitor Alerts - False Positives As Event ID 12290 Still Being Logged

Hi all,
I am using System Center 2012 R2 Operations Manager with the Key Management Service Management Pack at version 6.0.7234.0, and I keep receiving the following alert in Operations Manager:
"Idle Minutes Monitor Alert:
Key Management Service (KMS) inactivity exceeded threshold
Knowledge:
Summary:
The purpose of this rule is to alert system administrators to a possible KMS or network outage. This rule monitors the end-to-end operation of KMS activation. A notification event is created by KMS if no activation or renewal requests were logged by KMS
(activity event 12290) in the specified time interval. In addition to new activations, periodic renewal requests are expected to occur (default is 7 days). Whether or not this alert is serious depends on the number of machines in the KMS environment, how many
are actually connected, and the configured renewal interval.
Causes:
Any failure or incorrect configuration of the KMS service, other Windows components, firewall, hardware, network or routers can trigger the Idle Minutes Alert. This alert can also result from normal behavior, since it is possible that not enough machines
attempted to activate or renew during the specified time interval.
Resolutions:
The first step is to determine whether there really is a problem. Start with a known good KMS client and run (with elevated privileges) the script slmgr.vbs -ato . If the activation/renewal fails, it will report an error code. You can direct the client to
connect to a specific KMS machine by using the slmgr.vbs -skms option. The request event (12288) and response event (12289) in the Windows Application event log may provide additional information, including the identity of failing KMS machines. If there has
been a failure, check the following:
Software Licensing service (slsvc) is running.
Other KMS machine behavior is normal.
KMS firewall port is open (default is TCP 1688).
Attempt to connect to KMS using telnet to the KMS port(you won’t be able to do anything other than connect)
Use a network monitor (e.g. netmon) to capture and trace network problems.
There is one Idle Minutes Monitor that is used to monitor for activity. It may be desirable to adjust the time threshold, depending on expected KMS activity."
Despite what the alert says, there are activity events with ID 12290 being logged, but they are appearing under the 'Key Management Service' log instead of the general 'Application' log. I know that my clients are activating with the server without
any problems as I have run slmgr.vbs -ato with success on a number of them, and none are stating that activation is required. This issue was previously raised here:
http://social.technet.microsoft.com/Forums/systemcenter/en-US/1391acf8-f0be-4a48-9039-8d24e275f1fd/kms-idle-time-monitor-raise-wrong-alerts?forum=operationsmanagermgmtpacks, but I am running Windows Server 2008 R2 SP1 and the hotfix KB981314 comes
up as 'not applicable to this computer' so I assume it is part of SP1 now. I have also tried installing KB2692929, as that was cited as being a possible fix here:
http://social.technet.microsoft.com/Forums/systemcenter/en-US/8ec8ae5b-a310-4b0f-9a5f-e0599bceb93a/kms-managementpack?forum=operationsmanagermgmtpacks, however I am still seeing the same alerts.
Would greatly appreciate any further suggestions!
Many thanks

Hi,
I've checked for all the events that are generated by our servers, and there are periods of time where no requests are received for up to 18 hours, so that is no doubt why the alerts are appearing (we then sometimes see five requests in the same minute,
but there we go). I'll need to adjust the thresholds.
Thank you for your help, Chunky.1, I'll mark your reply as the answer, as it was very helpful in understanding the alert.
For anyone else who needs to check this, create a PowerShell script using the following content, and place your own details into the relevant sections in bold (without the brackets, of course). This will generate a csv file which will have the server
name in one column and the time that the request event was generated - you can then check the gaps between the requests. The script is quick and dirty, with no checks along the way, so feel free to embellish it as required.
Out-File "<directory to place file in>\KMS_check_results.csv"
$results = get-eventlog -ComputerName <KMS server hostname> -logname 'Key Management Service'|where{$_.message -match "<String which identifies servers instead of clients>"}
$filteredresults = @()
foreach($event in $results){
    #This splits up the message into sections, separated by commas, and places each section as an element in an array
    $event.Message -split ","|foreach{
        if($_ -match "<server domain suffix - e.g. contoso.com>"){
            $eventserver = $_
    $timegenerated = $event.TimeGenerated
    $filteredresults += New-Object PSObject -Property @{
        Server = $eventserver
        TimeGenerated = $timegenerated
$filteredresults|select-object server,timegenerated|export-csv "<directory to place file in>\KMS_check_results.csv" -NoTypeInformation

Internal temperature monitoring utility?

Is there any monitoring software (similar to Activity Monitor) that detects whether key components such as the CPU and hard-drive are running at a reasonable temperature or are overheating?
I believe that temperature-monitoring sensors are present inside the casing so in theory what I am asking about should be possible.

Hi, KDS-KDS. My experience has been that temperature-reporting utilities such as the one linked by roam above (which I've tested) are only able to find a single sensor in my Tibook, the same generation as yours. That sensor watches only the hard drive, which is normally one of the cooler parts of a Tibook. Though there clearly are additional sensors in the machine, it appears that their output is unavailable to (or perhaps isn't readable by) such reporting software, for some reason. Owners of other Mac models have reported quite varied results, from highly satisfactory (several sensors detected) to no sensors detected at all.
This question came up several times in the Tibook discussion forums a while back, and my recollection is that no Tibook owner, regardless of which of the four generations his machine belonged to, ever found any temp-reporting software that could provide a readout on the CPU. If you do find one, please post in over there and let us know.

Temperature monitoring for Core i3 CPUs

I have a i3 330M and lm-sensors results in nothing. Any ideas?

I've dug up some more info..
For temperature monitoring, a QST SDK is needed for supporting the ICH8 southbridge. The OpenAMT project is working on that (http://www.openamt.org/), but there doesn't seem to be much progess.
However, it looks like Intel will be releasing an SDK itself. See: http://software.intel.com/en-us/forums/ … hp?t=54851
Maybe after that we will have temperature & voltage monitoring support for all Nehalem and Arrandale chipsets.

The switch from coreduo temp, to temperature monitor

OK, it seems more accurate, allows to monitor both cores separately, bit i miss the processor activity level in the menu bar, anyone know of a replacement for this?

Thanks for your concern but you can't save me any money as I've already spent it!
As for the rest of your post, you may be happy to blindly roast yourself assuming that all is well but others have a little more curiosity. Yes, the MBPs run hot but they shouldn't run unbearably so. That there are many who reckon their MBPs are way too hot and many others who don't raises the question of "how hot is too hot?". CoreDuoTemp, Temperature Monitor and Hardware Monitor (the full version of Temperature Monitor) are tools to help answer this question. Comparing results with others will either reassure users or confirm their suspicions that something is amiss. Most MBPs fall into the "well, it's hot but it's a high performance machine" category. Some need a little attention to the thermal paste issue to get them to this level. A few have even been found to run so hot (>100C) that the chips clock their speed down to avoid frying themselves, severely compromising performance.
The point to take home here is that some people, myself included, are curious enough to want to know about their computer's workings and readings from diagnostic tools like this most definitely do make a difference as to how we view and operate our machines.

No sensors for Temperature monitor on the beige?

Hi,
I just tryed to installed Temperature monitor on my beige, and it reports that there is not sensors it can find on the system. Is it normal on the beige?
Thanks

Steve,
some other pieces of software ... used if you overclock your CPU or install a ZIF upgrade.
You should know that a ZIF upgrade with a G4 does report a CPU temperature with these programs, but that it is inaccurate (putting it mildly). Mine reads below room temperature. This is a feature of the G4 implementation, I was told.
I have a simple Radio Shack temperature monitor, a small probe on a one meter wire to an LCD readout. The probe wedges neatly into the heatsink, and can be shielded from cooling fan air with a small piece of foam. The wire can be lead out through the speaker area on the MT.
This probe picks up the difference in heatsink temp caused by toggling the cache on and off. It also shows that Sys 9 runs hotter than OS X, 48 C vs 42 C (varies with external temp. of course, here 26). Heavy Photoshop use will raise the OS X reading several degrees, but never to the level of Sys 9.
It also changes with its placement in the heatsink, and also with heatsink spring position. On time I didn't get the spring on right and saw a higher temp than expected so I could correct it. Also, my installation also has two small 12v fans (wired in series off the 12v disk drive supply so they run quieter) that considerably increase airflow over the CPU.

Programatically Monitoring RT Memory Remotely

Hello,
Does anyone know if there's a way to monitor the memory of an RT target remotely without using RT System Manager? I've been given an RT application that appears to have a memory leak. I'd really like to set up a logging VI to watch the memory usage over time, but without that ability it's hard to get a clear picture of what's going on. I'm aware of "RT Get Memory Usage.vi" and I've used it before, but I can't use it except locally on the target, and I'd rather not log to my cRIO's flash memory if I can help it. I suppose I could write some TCP code to regularly transfer the memory usage over to a Windows application, but what if the TCP code itself is causing the memory leak?
If such a VI or function exists, I'd love to know about it, and if it doesn't exist, it would be really nice if someone at NI released one.
Any ideas?
Thanks in advance,
Jim

Hi Stephen,
Thanks for your reply. Well, it's not that I can't use RT System Manager - it's just that it's a crude tool for what I'm trying to do. What I mean by this is that I'm using System Manager to keep an eye on the memory over a prolonged period of time. System Manager is a bit awkward because, to see memory usage all the time as an "alert," I've got to set up an alert that occurs when memory usage exceeds zero. Then, all the alerts occur at regular intervals. No problem; this works well enough. To log the alerts, there's no way to set up a file and have a sort of disk-streaming setup. The only way to log alerts is after the fact. This isn't so bad, but I'm working on a lot of really large applications all the time and I regularly crash LabVIEW, and when that happens, I lose all of the memory data. (I'm not at all saying that LabVIEW is unstable; Most of the time I have great luck with it. I'm just dealing with some very complex and unusal code on a regular basis) So then, as I said, it's not that I can't use it - I'm just hoping that there's a better way.
Apparently there is a better way! After I wrote some slightly frustrated feedback to NI's product support, Mike from NI got back to me, and he said:
"There is a new feature in LabVIEW RT 8.6 that should solve your problem (logging Memory usage on an RT Target). Every RT Target now publishes its CPU and Memory usage levels as variables under the NI_SystemState process. Specifically, you can read the value of
\\target\NI_SystemState\Memory\Allocated
to see the current memory usage of your target. If you have DSC, you can bind this to a variable with logging, or you can just read and log the value yourself."
Mike, if you're reading this, I hope you don't mind my quoting you on this one, but I'm very grateful for your response and I thought I'd share the wealth. I'm not using DSC, but I did successfully retrieve the variable using LOGOS via the datasockets protocol. For those unfamiliar with the process, I've attached a screenshot.
Thanks again to Mike! (And to Stephen for replying to my post)

No temperature monitors for Intel Macs?

I found the below in the FAQ for the application 'Temperature Monitor' and thought it might helpful to understand why we don't have a temperature monitoring application, or perhaps never will. SInce we do have the speedit.kext way to read CPU temperature, perhaps at least that is possible to implement in a standalone application.
Q: I am using the latest release of the application which should support my computer, but still no sensor at all, or only a S.M.A.R.T. hard drive temperature sensor is found. Is this normal?
A: Unfortunately there are some specific Macintosh systems which don't allow that sensor values can be read out by a normal application program. There are two different cases:
The computer uses a self-contained cooling control system. The hardware itself controls its own monitoring. No transfer of data from the sensor to the operating system is possible because there is no bus connection between the sensor and the actual computer.
The computer contains sensors accessible via a data bus, but cooling control is independent of Mac OS X. Apple does not provide any device drivers which would allow application programs to get data from the sensor. Only the firmware or a closed part of the operating system core has access to sensor data.
In both cases, it is not possible to develop an application program which could read out sensor values. The following Macintosh systems are affected by this problem:
PowerBook G4 Titanium (all models)
eMac (all models)
iMac G4 (all models)
Mac mini (all models)
Note that Intel-based Macintosh systems use a special mix of the mentioned monitoring techniques: Mac OS X only uses the load sensor of the graphics chip for thermal management. This sensor can be displayed by Hardware Monitor without any problems, it is however not displayed by Temperature Monitor, because this sensor does not measure temperature.
All other sensors in Intel Macs are controlled by special hardware working independently of the operating system, the Apple System Management Controller. This device has not been disclosed by Apple. There are neither drivers for Mac OS X, nor any documentation, and all details related to the function of this chip have been "censored" by Apple in the source code of Darwin. For this reason it is currently impossible that any application program could get readings from this chip.

"Mac OS X only uses the load sensor of the graphics chip for thermal management"
Yes and no. But, this doesn't really seem to be the case! If this is true, simply running Quake4 SHOULD cause the fans to kick on as the GPU is being heavily used. This did not happen on my machine. Only after reapplying the thermal paste would both fans kick in during heavy use. My guess is that it is actually a mix of conditions that cause the fans to operate at different levels. Heat pipe temp + GPU load + ...
I think one variable that is not being used is processor temp. I can't really understand why not though because that would go a long way to alleviating some of our heat problems and the fans would operate in a semi-normal fashion even if the processor/heat pipe connection is suboptimal.

Good Temperature Monitor for C2D MBP??

Just got my 17" MBP and it's great!!
I am new to the laptop world, so if someone can recommend a temperature monitor (preferably free) that would be great.
It seems fine, but I'd like to be able to monitor this.
Cheers

It may actually be overkill......
But this is the best one I have found:
http://www.bresink.com/osx/HardwareMonitor.html
It is an amazing product.

Temperature Monitor for OS 10.3.9

I need an application or console command that will show me the temperature of my CPU.
I'm running a Beige G3 that is using a G4 processor. It's running OS 10.3.9 through the use of the application xPostFacto. I've found the apps "Temperature Monitor 4.8" and "Hardware Monitor 4.8," but those don't support any Mac OSs below 10.4.x. Temperature Monitor 4.7 supports Mac OS 10.3.9, but I can't find a download of it for the life of me. All of the links redirect to version 4.8.
Please, any help would be much appreciated, my project is at a stand still until I can find something that works.
Thanks!

Click on my TMM name at left & send me an email. I'll send you the 10.3 version. Don't know if your Mac has the sensors to monitor the temps.
