Still Confused on Temps

[wchp]

I recently set up a new PC with at E4300 on a GA-965P-DS3 Running Vista OS
I immediately set out to OC it and got it up and stable @ 9x333 with vcore set to 1.425
Running a stock Intel HSF

Went looking for a monitoring tool and stumbled into speedfan, this forum and the excellent Core 2 Duo Teperature Guide by CompuTronix.

I installed Speedfan 4.32 and just presumed Temps 1&2 were right and that Core0 and Core1 were reporting correctly but... When I went to try and figure out how to set things in speed temp I posted and CompuTronix patiently attempted to help me. I have Installed, Uninstalled SpeedFan, Reverted to the hour after I installed the OS...
Bottom line, I just don't know what I am looking at. Speedfan just does not seem to be reporting anything accurately (to include voltages) I seem to have about a 15C delta between what Speedfan says is the core and what Core Temp says.
Core Temp says I have a TJuntion of 100C but the E4300 would be shutting down at that temp and here I am, days later still typing away and scratching my head as to what I am looking at.
The Gigabyte Utility reports the same temp as Speedfan, but has all the voltages wrong.
CoreTemp 0.95 is warmer, TAT shows the Core Temps Higher Yet. e.g. Core0 right now: Speedfan 32C, CoreTemp 47C, TAT 56C
all three at 18% load.
If I Start TAT loading the Core Temp 0.95 readings and TAT readings are the same

Could I (Should I) presume that I am seeing TJunction in Core Temp and Tcase in Speedfan.

Someone please slap me and tell me what I am looking at !

Which one do I trust to start adjusting FSB and Voltage to get to 3200?

TAT is the only thing you can trust. Run it at 100% load and you are going to shit your pants when you realize how hot your CPU is runnint at 3 GHz with the stock cpu cooler.

Also, from my experience, CoreTemp 0.95 gets the temps of the e4300 hundred correct (same cannot be said of CoreTemp 0.94 which read 15-deg lower). Tjunction in Coretemp should be ignored as it is not a reading but a static value.

If you want Compu's help, post your variables and readings in the format listed in the temp guide.

I'm concerned about several things:

Don't run TAT right now first thing.

Looking at SpeedFan if it is remotely right you are giving your C2D a vcore of 2v. This is not good. Which would explain those idle temps of 57-60c. Maybe speedfan is reporting incorrectly but on my system it is correct with cpu-z and my NVMonitor.

Also the displayed tjunction in coretemp is not what your tjunction is at. If you watch it you will see that it never changes, just like the vcore in core temp. These are just reference numbers it pulls from some magical hat.

I recomend you go in your bios and lower your vcore to 1.275 and see if you boot into windows at 3GHz. I know my 6300 boots at 3GHz with 1.225 so you are work somewhere between. But as of right now if you start up TAT you might have some serious issues.

 

[mrknowitall]

No, no, no. Obviously all the voltage readings in SpeedFan are wrong. Look at them. He has his Vcore at 1.425. 1.325 is stock He is not going to be able to overclock by lowering it to 1.225.

Basically, you cannot run that processor at 333x9 on the stock heatsink like you have. Super hot. Maybe try to set it back to stock speed and tun TAT at 100% and see your temps and compare them to those in the core 2 temp guide. Then start turning up the speed and checking the temps under TAT 100% load. Then wonder how you were running at 333x9.

 

[Silviastud]

Well I didn't know the stock vcore for the 4300 was so high... And it seemed like Speedfan was off but I didnt understand why. I was just trying to make sure he was playing safe. Sorry if i confused you WCHP was just trying to save your CPU.

No, no, no. Obviously all the voltage readings in SpeedFan are wrong. Look at them. He has his Vcore at 1.425. 1.325 is stock He is not going to be able to overclock by lowering it to 1.225.

Trying to squeeze it into the 640 width limit makes this a little fuzzy but if squint you are able to make out the numbers.
Here are all 4 apps and the various readings.
I understand TJunction in CoreTemp is static.
Temps 1,2 & 3 in speedfan aren't reading anything on my PC.
CPU-Z is reporting everything correctly. The Voltage is set to dynamic so as the CPU throttles back so does the voltage.
I now have the max voltage set to 1.38xx and TAT with single core lit off hits 76C after about 5 min. Lite off the second core and I hover at 78-79C (but I only let it sit there for about 30 seconds)
I have a Scythe Andy Samurai Master HSF coming (the Enzotech Ultra-X just seemed awfully heavy).
The problem is that SpeedFan does not seem to be reading Tcore or Ambient temp. Others seem to have SpeedFan 4.32 working without issue on the same MB (GA-965P-DS3 Ver.2) but they do not report if they are running Vista or not. (The values displayed are the sample values in the advanced setup screen and they never change)
The March 2007 Windows Vista Application Compatibility Update (KB932246) Lists Speedfan 4.31 on the compatibility sheet as one of the things it accommodates.
Maybe I should try reverting one version and see if it works better?

Point is, I need to understand which temps I am to believe before I start trying to come back up to 3.0-3.2 territory with the new HSF.
To do this... I presume after reading CompuTronixs' C2D Guide, that I need those to establish a base line to begin measuring temps and ambient and Tcore temps are required as well ?

 

[mrknowitall]

TAT is correct. Your core temps are VERY hot. You should probably turn down your OC until you get a better cooler.

 

[wchp]

So clocked back down to 1.8 (9x200) and set max voltage to 1.325 and...
SpeedFan Temp2 (Diode) suddenly starts reporting temps.
So now things look like this:

Idle (sort of) 11-17% load
Ambient air temp 22C
E4300 processor
965P chipset
VCore 1.050v(max)
1809 MHz
Stock Intel HSF

SpeedFan 4.32
Temp2 - 28C
Core0 - 30C
Core1 - 29C

Core Temp 0.95
Core0 - 45C
Core1 - 43C

TAT
CPU0 - 48C
CPU1 - 47C

TAT 100% load on both cores 10+ minutes:
Ambient air temp 22C
E4300 processor
965P chipset
VCore 1.264v(max)
1809 MHz
Stock Intel HSF

SpeedFan 4.32
Temp2 - 47C
Core0 - 48C
Core1 - 45C

Core Temp 0.95
Core0 - 63C
Core1 - 60C

TAT
CPU0 - 63C
CPU1 - 59C

The other question is does anyone else have a problem when OCing using speedfan?

i have the same set up as you exsept i have the ga-965p-s3 mother bord these are my readings

Ambient = 23c
Chipset = 965p
C2D = E4300
CPU Cooler = intel stock cooler
Frequency = 1.8 gig
Load = TAT 100% 10 Minutes
Motherbord = GA-965P-S3
Vcore = in the bois i have it set to normal witch is 1.325 but it seem that cpu-z changes from 1.28 to 1.34

idel TAT core 0 36c to 38c
core 1 37c to 39c
at idel speed fan is reading temp 1 35c ( not sure what it is)
temp 2 26c (this is the tcase )
temp 3 22c (ambiant)(offset +23)
core 0 35c to 37c (offset +15 )
core 1 36c to 39c (offset +15 )(Tjunction)

under TAT 100% core0 60c
core1 61c
speedfan under tat 100%
temp1 36c
temp2 53c (tcase)
temp3 22c (ambiant )
core0 62c (offset +15) (Tjunction)
core1 61c (offset +15)

over clocked i have similar reading as you do i to am wiating for new cpu cooler

you need to put an 15+ in to your speed fan core offsets and i had to put a 23+ offset in temp 3 (ambient)

 

[wchp]

i have the same set up as you except i have the ga-965p-s3 mother board
i had to put a 23+ offset in temp 3 (ambient)

I want to believe that Temp 3 is the ambient sensor but...
If you go to Configure, Temperatures you'll notice a Value of xx under the "Sample" column.
In my case Temp3 always reads -2C (no offset) which happens to also be the sample value.
Temp1 always reads 37C which also happens to be the sample value.
If I change the sensor type from Thermistor to Diode Temp 3 goes to 127C. This would present the possibility it was reading something but would not confirm the premise.
As I have never seen Temp3 change to anything other than -2C I am just not sure it is reading anything.
Just for amusement I opened my windows(the glass kind you look through (outside temp is 48F) and closed my office door.
Ambient air temp in the room has dropped to 64F/18C (down from 71F/22C)
I have 2 12cm fans moving 40+CFM per minute, One intake and one exhaust, so I would presume that the internal case temp is dropping because Temp2, Core0 and Core1 are all reading 2-3C cooler but Temp3 is still reading a steady -2C.

Have you ever seen it change?

Currently there is no program that will guarantee a correct read on the e4300. TAT and the new core temp build assume a tjunction of 100c, but intel has not published the actual tjunction specs of this chip/core. I am still wary of TAT as it was expressly designed for a different core architechture and intel states it should not be used on platforms other than mobile.

 

[h00kman2o]

now that i look at my temp 3 it hasent moved eather i was just going off what comp toxic told me he seems to know what hes taking about but i cant seem to get him to ready my temps since i put them in the format he wanted i have 5 80 mm fans so i to would think i would have plent of cooling for this processor but these temp isues that people are haveing scare e.i biult 2 identical systems one for me and one for my brother his tat core temps are like at 50 at idal im thinking he has one of those concave processors i have to take the pcu cooler off but hes one of those types if its not brock dont fix it people soi dont think his will be overclocked at all its so wierd i have reserched this comp for weeks befor i went and orderd it and did not see any thing about these temp issues till like last week im hopeing we can get these thing sorted out

h00kman2o, Temp 1 is your motherboard, and Temp 3 is likely your northbridge chipset, but there is no ambient sensor. Since your Tcase load is high, and Tcase Delta is outside the 25c spec, it's possible that your E4300 may have a concave Integrated Heat Spreader, so check it for flatness when you receive your new cooler.

Hope this helps,
