Quad Q9450 Sensor test (movement=0 for two cores)

Thread Starter 
Hi. I have had some problems with spontaneous reboots , and decided to install Real Temp to monitor core temperatures. The Reboots occured while playing warcraft III (the only game i play currently, so i dont know if it is a general problem). It only happens sometimes, maybe 1/10 games or less. Kernal-power event ID 41.

Real Temp showed unusual differences between core temps, and the temps for core 2 and 3, and are constant at 63c . My pc is not overclocked (i do realize this is slightly off this forums topic, but this was where all google hits about core temperature was).




I am mostly concerned about the core temperature, but also curious about solutions for the first mentioned problem.

I hope someone can help me, and i certainly hope i didnt make a rookie mistake with real temp .

hi mate and welcome to the forum
when was the last time you cleaned the inside of your pc? if not then you need to give it a good clean, google is your friend
if its clean

download prime95 http://files.extremeoverclocking.com/file.php?f=103
this is the 32bit version, use google if you need the 64bit one

install it and run torture test, and select large FFT test (max heat etc..) (how to guide in link below)
run this and keep an eye on temps in real temp.
never let it go below than 20 in the 'distance to tjmax' value

we need to see your load temps, idle temps tell us nothing.

does it cut out running this? if its overheating then you will either have to remount your cooler and/or change your thermal paste.

if not then run the blend test. (lots of ram tested)
how to guide here http://www.playtool.com/pages/prime95/prime95.html

if this fails then

download memtest86 http://www.memtest86.com/download.html
you will need to create a bootable cd and run this.
this will test your ram for errors, if any found your ram is on its way out

dont worry about the different temps, its common for a sensor to get stuck

Probably your sensors are stuck and they're reading the wrong temperature. So if you're 60C on core 3 (just an example) the sensor detects a lot more and forces shutdown. Just a theory, don't know if it's even possible

A temp sensor stuck means that it is stuck at some value and can`t go lower.
I got 2 stuck sensors. The only move higher but not lower. So a stuck sensor wouldn`t cause a false overheating issue.
It looks abit like you didn`t mount your cooler well. Please open the case and check if the "screws" from the heatsink are tight. I assume that you have a stock cooler and the "screws" are not that easy to tightern. To mount the stock cooler can be tricky.
I say so because it is wether:
- Two cores don`t get cooled (Mabe also a TIM issue)
- Or you got two sensor stuck @63°C wich is wicked
Anyway if you et a bluescreen you should post the code show there.

Thanks for the replies.
First check the screws, which were good (and yes the cooler was a ***** to mount ).
Everything is clean, since i recently had to replace Cooler, Motherboard and power supply. Originally only my power supply was broken (fan was noisy), i got a new one for xmas, which turned out to be broken. It occassionly had a short circuit, which fried my Motherboard -> new MB plus new cooler since the old one didnt fit .

I ran the prime 95 test with Real Temp as suggested by j. Col with the following results:


These i assume to be acceptable results, except that two of temperature sensors appears to be stuck.

I then ran the Blend test, which after awhile resulted in a crash -> Blue screen of death. I logged the temperatures which read: 37, 44, 63, 63 (i didnt get the error messege).

-> Probaly the ram. So now i will try to remove two block at a time and run the test until i hopefully figure which one(s) are broken. Fortunately they are only a couple of years old (Kingston) so maybe this will be a free round

Thanks a lot for the help guys.

Btw: Any easy way to locate the broken ram block, or do i have to switch them around and test pairs?

i would just test 1 stick at a time.
also i find memtest more reliable at testing ram then blend, but its upto you.
also going by the cool down test the 2 temps on the left are the right ones
