Duron 900 at 99C plus temps

[deez]

I have a duron 900 with no OC on an Epox 8KTA3 board as my work comp using the retail HSF with thermal pad. I installed Sandra about a week ago and checked temps and CPU temp was at 88.3C. I noticed a drop in performance yesterday and temp in Sandra was 109C so i rebooted and checked and CPU temp in bios was 99C.

I cracked open the case and apparently the wires to the ATX power connector were sitting on top of the fan and it was not spinning at all. This system was still running at 99C and had been running at least a week with no fan.

Info on the chip is
D900AVT1B
ANCA0117MPWM
F3362330244

And I have a screen shot from my original reading in Sandra

GOOD GOD THAT IS HOT!!!!!!!

Hopefully someone who knows a bit more than me can give you some advise on cooling it down, but i would change the thermal pad for thermal grease, and leave the side of the case off. also make sure the fan on the heatsink is spinning

Something isn't right there. I remember somewhere that the max temps for an AMD processor before total burnup was 90oC.

[chawken]

You are very lucky that the CPU still works. AMD Athlon chips have a max temp of 90c before total failure.
If you ran that chip for a week at over 90c, I probably would not trust it to live much longer. Then again, weirder things have happened. Maybe you should submit it to Ripley's.

This is why we love those 60 MM fan grills around here... :)

And for the record, AMD Spec max temp is 95C. They **claim** an Athlon or Duron can run normally up until that temp. We all know that realistically you really have to keep your CPU below 60 C for sure (and ideally below 50 C) during load.

That's crazy! I don't see how a system could run for any length of time like that (well, maybe a short period of time)

Sandra must be having some problems.. check your bios temps after you've run your system for a bit under a good sized load. Also, check another temperature monitor.

Let us know what happens!

Actually, for the record, Duron's are 90c, Tbirds are 90c and 95c, and Palomino's are 95c.

Yes this system was running at least a week (9 hours per day) with only a heatsink...no fan running.

Temps in sandra were right on. In fact i just bumped the jumper on the board from 100 to 133 w/o changing voltage or making any mods I am running at 1.2 with temps in the mid 40's after running the burn in 10 times. All I did was clean off the HS and chip with Tronic clean and apply radio shack thermal paste. Will run SETI over lunch and update.

Here is a current screenshot from Sandra....i just noticed that cooling devices are listed here when they were not in the above shot

[chawken]

That looks much better. Keep on Crunching.

Are you running 1.2GHz on that thing?! Plaese post a sreen shot of that! I would love to see that. What voltage is that at?
Wow....

[deez]

Well I just returned from lunch after running SETI GUI version for an hour and my temp in Sandra was 43.3C and in BIOS was 42C

CPU core voltage is 1.67v according to sandra

here is another screenshot from sandra as requested

Wow sounds like you took the burn in thing to the max. I would try a better heatsink and see what that duron will do.

[deez]

I would definitely like to do that but as this is my work computer and I do not own it I would not like to push it any more than that especially when that involves increasing FSB on PCI devices.

My boss is not too happy about me overclocking it already.

[Bender]

Your boss should be happy because you probably saved the computer from destruction. A cpu can only last so long at temps that high.

[deez]

yeah he was happy that i noticed....a few more days like that and it pobably would have been baked. The heatsink was too hot to touch and the thermal pad had melted and was actually running down the chip.

[jeff_harrison_344]

That has to me an error or something, it would burn on those temps!

[MiteyJoe]

nahh, i can vouch for him. we work in the same place..

he called me into his office goin.. "damn dude!! my processor was just running at 210*F!!!" I didnt believe him until i went in there and cooked my finger on his heatsink.

well maby amd has specified duron at 90c max....but its possibity that it could be able to handle 105c max befour it starts to burn...just a specification to keep that sucker cool i am running at 62c load and like 58 idle so i think some thing is wrong...and 1ghz@1350mhz now and man that baby is HOT HOT HOT...but i never got a crash or freeze...only when i bump up the fsb too much...that a pci device crashes....most likly from my state of the art 250watt PSU LOL...i think i need a 350 or 400 psu to get more speed then 1433mhz stabily....but i got 1350 now just to keep it a bit cooler

[deez]

I have a 300W Deer PSU....although durons need less power than athlons

I was happy to do anything with it at all. I wasn't even planning to OC that one (thats why I just stuck it on with the thermal pad) then once I realized it ran stable with no fan for a week I said what the hell and bumped it straight to 133FSB

nice OC Gunrock

JUST AN UPDATE

My Duron 900 is still running strong at 1.2 with no voltage adjustment or tweaking necessary. Temps level off in the mid 40's still

Amazing! :eek:
