Coolingproblem AMD Duron 650

[NicColt]

holy Cow, 29c and on a t'bird with a stock heatsink ??? and 46 under load hhhmmmmmm. I'm starting to question some of you folks. How can you go from 29 to 46 that's a 17 degree swing.
BTW what's with rain running?

My duron runs at 54c. I don't have any problem. Most durons a i see run around that temp. I don't see what the prob is. If you look up at amd you will see they are made to run that warm. Even up to 90c. So, you are worrying over nothing.

Case temp 21.3C
Motherboard temp 28.2C
Cpu temp 43.5C

I would really like to know what's holding me back from hitting the 900 mark any idea guys?.

My Duron 600@900 runs aroun 50C idle and 55C under load. No problems. I have wondered about maybe going to a Global Win FOP32 cooler, but hey, it is working and I don't want to mess with it any more. I will likely get a new HS and Fan when I move to a new Mustang core late next year.

damn it can't same one help me auto here. I mean i have obvious good cooling here as i writer the the temp is at 42.5 under full load (RC5) when i put everything in deafult the temp will be 33C. I can get max of 865mhz. I can't understand this what the heck is holding me back?. Can it be the videocard. I want to reach the 900 mark. The pc will even boot at 960mhz (not 1Ghz) but won't load win me. I think it's possible to reach the 900mark but i don't know what holding it back. If someone could help me out here i would really appreciate it (i want the 900 mark so bad i even am considering selling the d600 and get a d700).

I know that current Celeron and Pentium III CPU have thermal diode for core temperature monitoring. But Asus is the only motherboard the supports overclock and thermal diode for the Intel CPU's. If you get an Abit or MSI, you cannot use the thermal diode because the manufacturer left out this feature to save cost. Most MB review does not bother to mention this most important feature for overclockers.

Can anyone verify the AMD Duron/Tbird also have thermal diode. Please, provide AMD site address to support it. If it does, are there any MB that supports the thermal diode?

When I read this thread, it is interesting to note that nobody mention how he measures the temperature that was quoted. And if the temperature is measured by an external thermister, what temperature offset (degrees added to the measurement to estimate CPU core temperature) was used. When the temperature sounded too good to be true, it usually is.

Thermite,

You are correct, MADRAT was not. AMD Durons/TBIRDS do not have internal thermal diode.

 

[MadRat]

DaddyG-

No, MADRAT was correct. The current revision of the Asus A7V uses the Socket-A cpu's internal thermal diode to read temperatures. Previous A7V revisions used an externally mounted sensor.

 

[ColdTech]

I Have the 1st revision of the a7v &amp; it does use an external censor. &amp; I have that external sensor on the side of the heatsink nearest to the chipitself inside of the fins (chrome orb). If there was a way to get that sencer any closer than believe me I would do it.

MadRat, DaddyG:

I don't know whether the AMD Duron/Tbird have thermal diode or not. But I sure want to find out.

I visited the AMD and Asus web sites and cannot find any information to support MadRat.

MadRat, would you do us all a favor to post the links where you found the information.

 

[thermite88]

In the latest A7V manual revision (1.03 manual), it is still stated that a thermister sensor is included for CPU temperature monitoring.

Did anyone receive a late version Asus A7V without the CPU sensor, but a note about using onboard thermal diode of the CPU?

 

[DaddyG]

Madrat,

AMD cpus do not have a thermal diode. With version 1.02 the ASUS board uses a thermistor mounted in the socket 462 just like ABIT does.

Check out HARDOCP, Kyle made the same mistake when reviewing various heatsinks, then he retracted, confirming that AMD cpus do NOT have thermal diodes. The ASUS manual V1.03 clearly states that the sensor is built into the mobo.

 

[MadRat]

DaddyG,

In the same box there is a slip of paper that says its built into the cpu.

 

[thermite88]

MadRat,

What does the paper say? Is it referring to the thermal diode? If yes, it should be built into the CPU. If it is referring to the thermister, it will be built into the motherboard CPU socket.

If MadRat is not clear about the difference, would someone who has a late version Asus A7V clarify this issue.

 

[DaddyG]

Read the AMD technical specs, there is no pin-out for a thermal diode.

<< Read the AMD technical specs, there is no pin-out for a thermal diode. >>

DaddyG, I agreed with your observations. Since I do not have an Asus A7V, but am considering getting one, I gave MadRat the advantage of the doubt. If AMD has changed their CPU and Asus responded in their MB design, it may take awhile for them to update the spec.

However, 99.9% chance that you are right.
