Phenom II Max temp limit

[bkzed]

Hi,

I have Phenom II 965 BE, Its on Stock Cooler and is not overclocked.

the problem occured when I was doing 3D rendering, I was monitoring the CPU temps when Temps crossed 82c the system turned off and never started again.

I know the 82c is not normal but it happend because the heatsink fan stopped working, what u think is my CPU dead?

At work I have seen my i7 950 going 100c because of bad fan but even then the CPU survived and is still working.

I have tried diffrent PSU but still no boot. or is it my mobo? (the mobo is powering up i can see several LED's turned on) please advise me what to do to find out what is the problem.

thanks

82 Degrees is WAY not normal. The maximum temperature specified by AMD is 62 Degrees Celsius, and it's not recommended to be above 55 for stability. Chances are, you just killed your processor.

See if you can start a RMA with AMD.

 

[bkzed]

For my future upgrades I will never go with AMD because of its heating problem, Intel stands out when it comes to reliabelity even if it is little bit pricey.

Thanks I will start RMA, but what r my chances, can I get new chip from them?

 

[busydude]

How did you measure the temperature of your processor?

 

[airdata]

It should have shut itself off before anything could be damaged by the heat.

Can you try to re-seat your heatsink and make sure it is ok.

 

[Vesku]

Yes, unless something was very wrong with your motherboard it should have shut itself down rather than burn up. I agree with airdata reseat the heatsink first, then try a PSU and Motherboard swap or drop it in another AM2+/AM3 system if you are able.

 

[bkzed]

I was measuring tempretures with core-temp.

actually temp went between 82c to 83c and the system just turned off. tried with diffrent psu but no sucess.

didnt tried another mobo, but i do have am2+ mobo - M2N-MX SE Plus, i dont know whether it supports phenom II, what u think can i try with this mobo? do you think its mobo that failed because of high cpu temps?

 

[Vesku]

I don't see any Phenom II cpus on the M2N-MX support list.

 

[BD231]

Highly doubt you killed anything, try harder.

I wouldn't blame AMD for this. If it had anything to do with the CPU, it would be a poorly mounted heatsink. Any CPU would do the same given that situation, Intel, AMD or otherwise.

+10000 to this. High temps are not caused by the cpu at stock. Bad motherboard (giving it too much voltage) or HSF mount are the only ways to do this.

If you RMA, and it was your motherboard or HSF mounting, you will just kill another chip. Thats wrong.

Let me rephrase....

1) If your PSU was bad and killed the motherboard and/or the chip, RMA won't help
Fix: replace motherboard and MAYBE chip after getting new PSU. No RMA deserved.

2) If your motherboard gave it too much voltage and killed the chip,
Fix: buy new motherboard and chip. You don't deserve an RMA

3) If your heatsink was mounted badly,
Fix: remount, and it should boot. If not, you killed the chip and don't deserve an RMA. But the odds on that one are very high. Your chip should have shut down.

Odds that the cpu went bad on its own ? A million to one.

Well said.

The motherboard is probably just overvolting the cpu if you have it on auto.

 

[bkzed]

Thanks for your suggetions.

But is 82c will burn the amd cpu completly without shutting down itself?

and lets say if the cpu is gone and mobo is ok then can I get to bios witout cpu working?

 

[bkzed]

I do have Athlon 5000+ 2.6 Ghz (brisbane) in spare can I use this one to test my mobo?

My mobo that I was using with Phenom II is MSI-785G E53

 

[Mr. Pedantic]

If the CPU fan is not running the CPU won't get past POST, even if it does start up.

As for the BIOS, you have to use an AM3 processor, which essentially is just Athlon IIs and Phenom IIs. That Brisbane will not do, I'm afraid.

I tried the cpu with Asus M2N MX SE PLUS motherboard, and this time it took me sucesfully to bios but it dosnt show real freq. of cpu but it did show the name (pls see image below).

I also tried to attach that old HDD where windows was loaded and it did start to load windows but restarted after some time

does this mean my cpu is ok?

 

[Vesku]

That motherboard does not officially support Phenom IIs as I stated earlier. Most likely your chip is good though, since the motherboard detects it even if it doesn't know what settings to run it at. I'd suspect the MSI motherboard it was in or a cpu cooling issue. Is this an OEM computer or self built, as the power supply still has the potential to be providing unstable power?

 

[bkzed]

I think it was PSU who killed the motherboard (psu i was using was the one that came wth cabinet and cabinet cost was only 35$)

this time I used CM xtreampower 600w psu, I tried using another good heatsink and this CM psu but the MSI still dont bootup.

Just want to give u guys some details of mobo and what happens when i turn it on.

MSI board has some APS(active phase swithcing) LED's turned on, thier are total 5 led's in line like below-

*|****

as per the manual the first led is NB , and from second to fifth led's will show the the power phase that my cpu is using.
when i turn on computer all led's turn on except the second one.

also there are 3 buttons on mobo - power/clrCmos/reset all the lights of these buttons also turn on.

 

[VirtualLarry]

From your description of the LEDs, sounds like you burned out the primary VRM phase.

 

[bkzed]

what is VRM? is it something that can be fixed or do i need to replace the mobo?

Voltage Regulation Module

Definitely requires replacing the mobo, unless you're REALLY handy with a soldering iron

 

[fffblackmage]

Voltage regulator module. Like what the name implies, it regulates voltage and supplies power to the cpu. I think ram has their own as well. I doubt you'll be able to fix it if it is fried; just replace the mobo.

OK then I will replace the mobo but are you guys pretty sure that my CPU is safe?

 

[tweakboy]

I think I know the answer to this one.

Honestly Max temp is 100c ,, it can work at 100c when your gaming or doing intensive stuff rendering etc.

You want to keep the idle temp in the 40's Celsius and full load throttle to 60's and 70's Celsius.

If your temps are in the 80's and 90's on load then I pray that CPU stays alive for another month or soo.
