Quad core temps

[PorPorMe]

I just installed a Quad. (CPU Type QuadCore AMD Phenom X4 9650, 2300 MHz (11.5 x 200)
The temps in Evererest are troubling me. It reads temps on the 4 cores at 20c EA. but CPU temp is 70c idle. Should I be concerned with this?

[ThunderRd]

Too bad you didn't wait a week for stock; the 2.5G 9850 fell $30 to only $10 more than the 9650 a few days ago:

Weekly CPU Prices - Week of August 10, 2009 - www.sharkyextreme.com

Clearly the 20C temperature is incorrect. Do other temperature utilities read the same?

[PorPorMe]

Speedfan is a carbon copy on temps. SMP takes it to 80c-all cores at 100%. I don't like it reading that high-are quads higher temps or do I have a cooling problem?

[PorPorMe]

I removed the aftermarket cooler and installed the stock one.
Idle temps: CPU 80c
Cores 34c each
SMP temps: Cpu 96c
Cores 49c each
Speedfan records only one temp for cores-38c and 49c-and then temp 3 as 80c and 96c.

It looks to me like the core temp is behaving right-in the right range anyhow-but the readings of 80c and 96c are extremely bothersome.
Logic tells me the core temps are correct as a temp of 96c is a little readiculess, but if I'm wrong!!!!!!!!!!!!!!!!!
I've shut down SMP for now-temps are 76c CPU (Everest) and 28c cores.
Advice or thoughts are welcomed!!

Still, 20C has to be wrong. That's under 70F-cooler than your current ambient in August, I would guess, so it can't be. It must be something with the way your board sensors are being read but I don't know enough to say.

Q1:Yes.
Q2:Maybe. Or probably. 80C sounds too high, but I haven't used a Phenom. My Q6600 is 55-62 at 100% depending on the WU. I'd check the cooling. Then again, we're not sure the sensors are being read properly, are we. If the 20C is wrong then the 80C may also be wrong. See if there are any known issues with your board/chip/sensor combination. What does the BIOS report at idle?

[PorPorMe]

I didn't think about the bios-36c CPU and 38c system temps. I set a 80c CPU warning and just kicked in the SMP.
CPU is at 98c-no bios warning-core is at 48c.
That CPU temp has to be wrong/speedfan is roughly the same. system 3 at 96c and core at 47c 100% on cores.
This is with the stock HSF. I'll let this run for a bit and reset the warning to 70c and even 60c on next run. I think I'm OK.

EDIT: No CPU temp warning at 70c, or at 60c. That is the lowest bios temp will give me.
Both programs are reading consistant except the first ru of 20 something. The readings of high nineties has got to be a bad sensor on the Phenom-a bad reading the first run of 20c.
everything is smothe,
Tomamarrow I'll reinstall the Thermaltake cooler and read how to set SMP up on Quads.
Houston-It appears we have no problem

[bonesaw]

did you replace from a dual or do a fresh install. because when i installed my quad from a dual on a old os i had some problems i dont know if amd will give you a hard time when doing that.

[ThunderRd]

That's a good point. Many folks have had problems with dropping in a quad onto a dual setup without an OS reinstall. Usually it's with the OS seeing all 4 cores, although that's not a problem in this case AFAICT.

[PorPorMe]

This was drop it in and go. I'm running 2 SMP clients and the GPU client.
I'll install this, the Thermaltake Spin Q cooler, and report new temps.
Then do a clean install of Win 7.

[PorPorMe]

We have a sensor problem-not a cooling one. Installed the squirle Q and IDLE temps are 68c for CPU and 20c fore cores.
With 2 SMP clients running, and GPU, 79c CPU and 37c cores.
I'll check bios agian and post that.

EDIT: Bios temps are as follows,
System temp 44c - CPU is 27c

[ThunderRd]

I'm still confused. How can the core temps be less than the CPU temp? It doesn't work like this: temp1+temp2+temp3+temp4=CPU temp. That is like saying that if you have a boiling pot of water at 100C and another at 100C, and measure them together, they are 200C. Core temps are always higher than CPU temps.

There must be an easy solution; surely it has something to do with how the software reports the sensor temps. Did you find any known issues?

[PorPorMe]

Everything is running fine. I ran win perfomance test and all #'s reflect the upgrades. (new memory as well)
I haven't run prime or any other stress program yet. Mabe I'll install 3Dmark Vantage and run that befor a clean install-that should pick up anything haywire-don't know what else to do.
It almost has to be a read sensors problem-not a temp problem. remember I have a bios warning set at 60c for the CPU and there hasen't been a peep out of it.

[JimF]

Might be worth trying Coretemp: Core Temp
or CrystalCPUID: Crystal Dew World - Software - CrystalCPUID

I've found these seem to handle sensor offsets better on some boards.
Crystal also permits tweaking voltages / multipliers etc.

[PorPorMe]

Clean install is done. I have 2 SMP clients running [4 cores at 100%] and the GPU client. 32c [impossible!] in Everest, Speed fan, and Core temps. Now I'll do Prime95 and see where the temps go.
EDIT:
Running prime95 on 4cores with a temp increase of only 4c. Is this cooler that good? I can't wait to start OC'ing this baby!

[ThunderRd]

OCCT or the SMP folding client will both bring on higher temps than prime 95.

[PorPorMe]

I added prime to the mix-on top of SMP. My gut says everything is fine.
The little guy on my shoulder says "Idiot, you can't afford the game your playing!"
The bios is set for 60c warning. If I can trust the bios readings, then I know it's the core temps I should focus on. so my next step is to turn the CPU fan down and start stressing again.
right now, the core temps are low but consistent, could it be that the cooler/case combo are that good?
The last prime run was 4 1/2hrs-
While I'm up-I'm going to turn the CPU fan down to nothing' and see I f I can't break 60c, While i can monitor it, Then I'll run Prime all night long. MY gut tells me everything is OK-but the numbers don't agree.
Time to go ride with the devil!

EDIT: Children, Don't try this at home!

[PorPorMe]

Prime95 ran over 6hrs, with SMP running, no errors.

Minor OC was next step. Will run Prime agian tonite.
3Dmark Vantage somewhere in the mix.
Temps are great if I throw out that 90c SOB!

[MUff1N]

What's causing the 90c reading? Seems rather high for whatever it is...

Anyways, the newest version of Speedfan is v4.39, so
you should be using that as it supports all the latest processors, chipsets & sensors on the mobos to give you the correct reading on them.
