Nice app….. I’ve never been much for running “Topless”. I usually only pick up a few degrees anyway, nothing that could really help an OC….

Testing with this app I found I was running:

Core #1 @ 41 idle and 58 load
Core #2 @ 36 idle and 48 load

Finally a tool that can detect a problem…. Needless to say I popped the top.

Results:

Core #1 33 idle and 45 load
Core #2 33 idle and 45 load

Pretty damn cool! Guess it’s time to bump the clock!

Thanks again - Great Tool....... :) :)

You should definately contact the creators of the other popular monitor programs and share your findings so they can implement the same into their own creations. Not that your program isn't adequate, but it would be a shame not to spead the information. I assume that commercial profit from this isn't your goal anyway =)

-Stigma

Not quite.
The mobos read the temp using external sensors connected to the internal diode inside the CPU. So the accuracy of the reading will really depend on the quality of the sensor and on the quality of the signal which that little diode is putting out, going outside the CPU, into the mobo's circuitry and into the external sensor located on the board.

a few minutes ago i popped the top on the little sucker and put it back under water...almost 20C drop in load temps was the result. i am not one to trust such a wide swing and was curious to know if you think a naked core would effect the temp readings that much?

Are you speaking of a 20C drop via Core Temp? If so its quite possible I guess, if the IHS had really poor contact with the core. Also IHS represents another layer of material interfering the HSF/Waterblock to take the heat away from the CPU core as efficiently as possible.

That is some interesting info. I wonder if this kind of result will be consistent or not.

yeah, 20C gap between the Core Temp readings. the contact looked good, that is what stumped me. i thought perhaps there was something else going on because 20C seems waaaay to much for just the IHS coming off unless of course it was dry under there but it wasn't. the thermal paste looked in really good shape. thanx for the response.

I noticed a big difference in the temps on my a8n32-sli and fx-57 the asus temp program and speedfan both report my cpu temp as being -12c at idle in windows. your program reports the core temp as being -28c (im running a prometeia mach II) I hope you program is right as being i like your numbers better :) I really think you should have the title of your thread changed now that you have it working on processors other than the Rev F chips. and i think you should have it stickied on one of the forum topics, finally there is a way for people with fairly current hardware to get accurate cpu temps. As soon as my jinuv2000 ss phase shows up and i build my fx-62 system i will be downloading all your software and sending you a paypal. Very nice work, Thanks a ton. Please keep working on it. Give us a speedfan type app but with your accurate measurements, logging and gui enhancements are all thats lacking.
Thanks again and my paypal is on the way

i finally have some screenshots of Core Temp in action, catching the AMD IHS napping. notice how the idle temperature at a lower clock with less volts is higher than the load temp with more volts and clock. if i didn't do the testing myself i wouldn't believe it. no IHS makes the waterchill unit look king ;)

290 x 10 / 1.60v set in nTune / IDLE - w/IHS max CPU on waterchill

300 x 10 / 1.65v set in nTune / LOAD - wo/IHS max CPU on waterchill
http://img.photobucket.com/albums/v2...300x10_1-1.gif

bloody hell i hate not having working programs for voltages and whatnot that are ss friendly. ntune works with the C51 for clocking and is the only way i can get past HTT290 but to take a ss with any amount of info...forget it.

Firstly, nice proggy Coolest :clap: Many people have been waiting for something like this for a long while.

I thought I might make you aware, when running OCCT & Core Temp simultaneously, the Core Temp reading jumps straight to -49 until OCCT is exited.

Not too much of a biggie as I can just run Prime, Stress CPU etc but thought I may as well make you aware while the proggy is still in beta mode.

Best of luck :toast:

this is the best program i have ever used

for people who are a having a weaker core, or what they belive to be weaker isnt so

i was getting 60c load on core 1 then 40c on core 2

if u run prime watch the core temps, slowly adjust the screws on you heatsink until the temps are close or the same, then u will notice your weak core will run alot better

I had 20°C dif6ference between core0 & core1 !
My waterblock barely made contact with the core (it's a naked chip)
I tried to correct this while the system was runnning , very stupid of me.
I think I killed my cpu :(

But anyway , cool program :toast:

I tried it out on my opty 165 seems to work great altho its a bit awkward cuz my core 0 shows up as core 2 and my core 1 shows up as core 1. Or at least i think it is. When i load core 0, core 2 goes up more but when i load up both cores core 2 has a lot lower temps but fails earlier, weird.
Core 1 would go up to like 60C but keep going while core 2 fails at about 50C. Also i noticed the program sometimes jumps to some crazy number then goes back to normal.

Question:

How low temps would this sensor be able to read from a conroe? I will be phase-cooling one soon to very low (far sub zero) temps.

I don't know. The lowest reading possible in theory is TCaseMax - 127C. But the lowest I've seen this far was 4C even at sub zero cooling.

Just got my rig back up, and I have some cool results

http://img289.imageshack.us/img289/4775/temps1hv.jpg

This is a naked 4200+ X2
There is a 4C difference in temps between the two cores at idle, and MBM5 seems to report cooler core temp (or just Core2's temp)

At load though, Core1 spikes all the way up to 40C! I don't think that it is a bad paste job, because I have had many problems overclocking this chip. No matter what I would do Core1 would ALWAYS fail really fast, while the other core remained rock solid, most likely due to the temperature difference. Has anyone else seen this?

Hopefully I can find a fix for this and get some nice clocks :P

BTW, does anyone wana test a CPU in a 4 phase mobo compared to a 3 phase and see what the "real" temp difference is? :p:

my core 1 is 38C and core 2 is 40C .. im using the stock Opteron 165 HSF and AS5 .. why 1 core is like 2-3 C higher than the other ?? And i heard Opteron hsf are good.. i also just removed stock pad and applied AS5 .. still hot!! Is there something i can do/check to make it better or this is normal?

Following up with my post, if I prime just Core1, its temp stays near idle/low, but after I kick in Core2 (even if Core1 isn't being primed) it spikes up to 40 instantly:confused:

After some testing I think that core 1 may be located on the left side of the chip, that is closest to the back side of the case...

I just loaded it up on my 3200+ NC and it looks like core center is only a couple of degrees off from core temp under load. When it's idling core center is way off. Core temp reads ~48C under load while core center reads 50C. While idling Core temp reads like 40C while core center reads like 36C.

Want a GCPUID dump for it?

This is with watercooling, but it's like 90F in my room right now so it's not like I'm going to get awesomesauce temps right now.

A nice feature, if possible, would be an adjustable high temp warning.

Well CoreTemp and MBM5 are definately reading too different things. :)
CoreTemp appears to be reading CPU Diode and MBM5 (DFI version) is reading CPU Temp.
Using different programs to "load" the CPU also seems to make a difference between the two readings.
I'm not sure what program Pyr0 was using but I AM getting a large difference dpending on which program I use. (Thanks Pyr0)
Using SP2004 the difference was minimal (couple of degrees as I posted earlier).
Using SuperPi mod 1.5 the difference was much greater
Same thing when I used the System Stability Test in Everest Ultimate

I did some screenshots using Everest Ultimate v3.00.645 BETA.
(I would think the TRIAL will give you the same info)
I enabled On Screen Display and monitored CPU Temp AND CPU Diode in it.
Then set Everest to "poll" every 5 secs (same as MBM5 DFI config file). Took a bit to somewhat sync the two.

(I'm still amazed at how useful Alex Van Kaam's MBM5 is since development was stopped over 2 years ago. I've tried to color code the readings)

I than ran OCCT and Core Temp read a constant MINUS 49 degrees (wonder is it can read any lower? - I assume it is not working when OCCT is running))
As always MBM5 dashboard is not visible when running OCCT, but Everest Ultimate displayed just fine.

Everest Ultimate has a Program under "Tools" called System Stability Test.
It stresses the CPU to 100% and you can see the Vista Sidebar reflecting it at 100% also.

I'm gonna try testing with different OSes again and different methods of "loading" the CPU. Willing to bet that Vitaliy Jungle's "Next Sensor" Program is going to give some pretty similar results. Hopefully I can get my hands on a dual core rig over the next two days to do more tests with.

The thing is i see OCCT uses the same type of driver that Core Temp uses. But core temp dynamically loads and frees the driver (enables a user to run multiple instances of the program). OCCT overtakes it and when Core Temp tries to read the temperature and fails, reports a '0' to the function that calculates temp and as the temp calculated by "Temp == Value - 49" this results in 0-49 = -49C displayed.
I think I'm going to rename the driver when I get the chance, this way should not conflict with any other software.

First of all there's a thread in the Intel section as well, I suggest you post this there.
Second, the B0 rev seem to be reporting some crazy temps via the DTS. The few B1s that I saw, on the other hand report temps that make sense and seem to be at least somewhat accurate.

thanks, when i ran it for the first time my computer shut down. but... it was at 3am and i forgot to set back 1 of the 500 settings i changed that night

NEW Question,
@2900mhz with my ihs removed and Ceramique
mbm5 was reporting:
idle40 load51
core temp beta
idle31 load51

@3000mhz ihs removed & Coollaboratory Liquid metal
mbm5 was reporting
idle37 load46
coretemp beta
idle31 load42

also my water temp after cpu,chipset,2x7800gt is about 31c
so would the idle of 31c be about right or the 37c?

it is hard to beleive i got a 10c improvement from this tim but im now still priming @3000mhz both cores are with in 1c of each other

Everybody will get the error, its a bad compile. TC neglected to test his release build (although he doesn't even have an A64). He has gone to sleep or work so it'll be a bit before its fixed. Hang in there.

Hmmm, I'm sorry. I guess compiling and 4am don't mix to well.
I think it should work now, try it out.

works now thanks :)

temps look about right, I knew my temps reported in smartguardian were off...I just couldn't believe i was at 44C full load at 1.6v and using the stock cooler.

One observation of mine: CoreTemp doesn't seems to refresh the CPU frequency reading, but does VID. IMHO this makes logging CPU freq pretty useless b/c the same freq is being reported all the time. It just writes down freq CoreTemp detected when it was started.

Oh damn, you're right. lol. I guess I'm not paying attention :|
Either way can you let it run for a while and see if it crashes after some time?

Works now, only thing is it reports the stock vid not the oc vid, but gives me the oc frequency and not the stock one. :)

Theres a good 7-10c difference between core1 and 2. Guess i might have a bad mount with the water block.

hmm smart guardian is pretty off, this gives a much more realistic reading. also explains why core 1 craps out consistently before core 0, theres about a 4c difference. Now, I think its time to move on to my tuniq tower lol.

My readings are still lower than ambient/water temp. The CPU block itself is 6ºC warmer than the readings on Core Temp Beta 0.9.0.91.
I gather this issue is based on the sensor offset. Was there a fix for this?

I believe that the problem with your readings are related to unproper calibration of the DTS, from some testing I've come to the conclusion that the offset is for the mobo temp sensor.

Could you try remounting your block to see if it helps?

I don't think that will help. My core 0 consistently reads lower then ambient. The odd thing is the average of the 2 cores is what MBM reports. I believe the error for core 0 is an AMD problem.

Abit EQ shows 49C; your prog shows 54C and 40C. (54+40)/2=47C ?

Nice program.
My Smart Guardian shows about 26-27C while this program shows from 20-22C core 0 and 13-15 core 1. Thats probable why core 0 is the first one to fail when pushing for more than 3GHZ while core 1 seems to hit 3100.

Update: Just tried dual priming and noticed that at load my core 1 (the cooler one) reading matches the Smart Guardian readings at about 41C while core 0 is hitting 48C

Second update: So much for my theory on my failing core...the hotter core is actually the one that OCes more! I guess its just a simple weaker core case for my cooler running one...if you can call a 3ghz on air weak that is.

EPoX's USDM software shows my load temperature to be around 41 degrees under prime95 64 bit. This piece of software shows 37 degrees.

By the way Asus PC Probe reports CPU at a steady 41*C :confused:

I remember getting the same bouncing with MBM5 back to the days when I was OCing my old Barton.

This thing says that my idle temp is about 5C higher than I thought, but load temp is the same as all other programs report.

EDIT: Just realized that it reports my idle temp as the same temp I get in the BIOS. But BIOS temp is under 50-80% load. I think the idle temp this program is reading is actually BIOS idle temp, which is several degrees higher than true idle temp.

According to this appy, my other PC loads at around 48-52*C. It's a 3000+ Venice w/Stock Cooler & AS5. All in an Antec Solution Series case with a Vantec Stealth in the rear and a low-rpm Antec fan in the front (like 40CFM for each fan prolly). The case is then in a desk enclosure thingy, so I guess the temps arent bad. The PC's inaudible which is nice.

my second core is +4C .. so its definitely a bad mount? do both have to be exact same?? and lastly i have arctic silver5 applied.. so when i remount, do i clean all of it, put AS5 again and then mount?

no, its probably not. i think its the ihs on the chip thats not mounted well. this program ruined my day lol, my tuniq tower idles barely any lower than stock. its a shame as i have a decent stepping, but just cant seem to get the temp down. second core at 37-39 is still too high... its stock voltage too

I'm not finding core temp to be too accurate on my newcastle. It reads the same idle temperature of ~40C regardless of what I do. I put ICE COLD water in my reservoir, core center and sisandra both showed my temps drop way down to below 20C. Core temp showed no change. I didn't get a chance to measure load but I'm running a dtek WW block and BIP2 radiator with lotsa air flow. The water in my reservoir is freaking cold. The block is mounted on there as tight as hell with thermal goup. I think the DTS on newcastles are a bit different.

Full load, 2.7GHz 1.56v. XP-90 w/Panaflo M1A (Lowest Speed Model). CPU is Naked, XP-90 is modified to mount to naked CPU's. Arctic silver Ceramique is the TIM. Outside temp is 81*F so I'm guessing 72*F down here with 4 PC's on full load. (basement). PC has been on for approx. 4 hours, full load and some gaming.

Seems very accurate :)

Has anyone with a very accurate measuring device been able to compare how accurate this program is at reporting temps?
07-13-2006, 01:27 PM

The difference in readings between core 0 and core 1 may not have anything to do with the improper mounting of the HS or IHS. See my post above. Core 0 consistently reads below ambient temperature. As we all know that not possible with WC.

heres a text dump.
939 opteron 165 @ 2.7 0550upmw

reads 37c dual rosetta load on water. motherboard reports in the 40s.

reports stock voltage and only 35w tdp, though set in bios at above stock.

Excellent application :)

Shows me 32-36 idle and 38-40 load on scythe ninja with fan at 800rpm 2.7ghz stock volts.

Not bad considering how hot the weather is in Uk atm.

It seems that if you would run without an IHS, you would mess up using the TCaseMax calculated for the CPU, as you have removed one TIM joint and the IHS. Which could account for temps below ambient.

In fact The Coolest can you explain the logic of using

TCaseMax-delta from TcaseMax = Core Temp.

I am missing something I am sure is right in front of my eyes. It would seem to me that

Fixed Value(unknown at present) - delta from TcaseMax = Core Temp

makes more sense to me. The sensor I would think will give whatever it's output the same for every CPU, if that output is calcualted into a delta from TCaseMax and that is what is put in the register then that's what it is, but why would that not be subtracted from a fixed reference value for all CPU's of a certain type from that point? Ahhh maybe I am too sleepy and will think about it tomorrow...

Also I would think the DTS would have a temp range spec for which the accuracy of the readings is within a certain tolerance, perhaps the temp sensor was not desgined for sub zero operation and account for off the mark readings in "Core Temp", just throwing out ideas for this one.

Opteron 165 no IHS. Water cooled.

14/27 idle
33/42 load
ambient 24C

GREAT SOFTWARE THOUGH!!! I love where it's going!! Anyway part of the below ambient crowd...

With that big of a Gap between your cores I would try to reseat your water bloack as you probably have bad contact.

Here's my Naked X2 at Idle and Full Load.

There is no way u could cool below ambient with water cooling without cooling it actively like with a chiller or sticking the radiator in a frigde/bucket of ice. things like that.

The IHS isnt on mine and im getting 33c/24c idle with an ambient of 21c.
