I have been running a Duron 800 for over a year now. I have an Asus A7Pro motherboard with 512M of RAM and an Asus V7700 video card.

Last night, I purchased an Athlon 1100 and installed it in the system. Now I can smell something burning in the system. I know Athlons run hotter but to actually smell it. I have the CPU fan, which is AMD approved, as well I have an extra case fan in there. I have monitored the temp of the CPU and it is only up at 52C. I don't think that is exceptionally hot, however, I have had stability problems since it was installed. Sometimes programs work, other times they don't. The system locks up sometimes.

Any ideas as to how i can fix this. I ran a test with 3D Mark, and at 1024X768, 32b colour, I got a 3100. I was disappointed with this score.

Any ideas?

Thanks

Slyguy:

Read my post in the thread where the guy underclocked his 1800+ to get stable (just above this thread I think). Main point is: You probably are over-taxing your Power Supply. Though the fan info probably applies to, to some degree at least.

When you installed the new cpu, did you clean the heatsink, and apply NEW GREASE (arctic silver II is best here)? If you used the TIM (thermal interface material) that comes on the heatsink, and applied it to the new cpu without changing it you'll run much hotter most likely. After being hot for eons the stuff won't remold to the new cpu slug and usually ends up with gaps, which trap heat and raise the cpu temps. Give your PSU info that I asked the other guy for (3.3v, 5v etc...amps and watts combined etc).

That would be helpful in determining if your psu is the most likely culprit. Which version of 3dmark? 2001 scores are much lower than 2000 scores. With no Geforce3 scores suck in 2001.

The burning smell could be lots of things, including the PSU and any thermal paste you have on it. What kind of burning smell is it? That's a tough question, but it would help if you can answer.

Alright. The computer has now been running for several hours, and the temp is 53C/127.4F. As for the smell. The only way to describe it is like a burning chip. The system seems stable enough for now. I haven't had any lockups today, but that smell. Something isn't right.

Now I am not sure how to figure all that stuff out on the PSU that you asked for so I will just tell you what kind it is. It is a Sparkle FSP300.
AC Input 115/230V
10/5 A
60/50 Hz
DC Output: +3.3V`28.0A(org)
+5V`30.0A

Max Output Power 300W (+3.3V & +5V & +12V=280 Watt Max)

This PSU was on AMDs list.

Thanks again.

Make sure you keep wires away from the HS, that could cause the smell.

I did check that, and made sure the HS was clear.

If the system is unstable and there is burning smell,the chip is running too hot.Don't trust the temp readings,they can be very inaccurate.
there is propably "a thermal gap" between the cpu and hsf.You should remove the hsf and clean the contacting surfaces thoroughly.Q-tips and isopropyl would do fine,or some other solvent that leaves no residue(nothing like vodka).New thermal past and reseat the hsf.

I once tweaked my amd1200B fsb from 100 to 109 and the temp reading rose only 1 degree C,but the box started to smell like burning rubber(in about 5 minutes time),so I gave it up.

Seems strange that I should have to clean that even though it's brand new. Should I scrape the old paste off before I add new stuff, and how much do I add?

If you reinstall the hsf it's just a general advice you to do it from the beginning.If the hsf has a bad contact it maby doesn't help just to take it off and reseat it.
We dont know what is causing the problem.hsf might leaning on a side.There might be dirt in between lifting the hsf.

A thin layer of thermal past on cpu core is enough,because the gap needed to fill is only roughnes of the hsf butt and the cpu top.

It is possible to missaligne the hsf when reseating it,since there is no guidance.Use force on the spring only,not the hsf.

Reply to Era

So if I am using new thermal paste, do I scrape off the old stuff first?

Yes.And do it well.
Do you have isopropyl or alike solvent?

I'm in a bit of trouble here because I dont know how detailled I should be.

Reply to Era

Yes, I can get some alcohol. You don't have to be extremely specific. I know computers, but this whole CPU and heating issue is new to me, I have never had to worry about it before. I am going to pick up some paste today. I had an awful time getting the HSF on in the first place, and I am guessing the 2nd time won't be any easier.

I deletid my last post.If you saw it i'm sorry.

When I chanced my hsf for a quieter one,I thorougly rubbed the core and hsf butt with Q-tips dipped with isopropyl and I really overdid it.I almost managed to erase the amd logo.
Then added some noname thermal past on the core and seated the hsf very carefully.I lined it up with the socket as well as I could and pressed the spring ower the noch.(I had to bend a perfectly straight and good screwdiver to accomplish the task).But it all went well and I never had any trouble since.

If you are getting ArcticSilver II(which is the best(for what I'm told))be carefull with it.It's electrically conductive.If it gets on the bridges you might have a dead cpu.

::the golden armored mythslayer appears::

Mythslayer(me)~ ARCTIC SILVER IS ONLY ELECTRICALLY CONDUCTIVE AT HIGH PRESSURE, YOU CAN SPREAD THE CRAP ALL OVER YOUR ENTIRE CHIP AND IT WONT SHORT OUT THE BRIDGES!

Submyth~ EVEN IF YOU SHORTED ALL OF THE BRIDGES ON THE CHIP PACKAGING IT WOULD NOT FRY THE CHIP, ONLY CAUSE IT NOT TO BOOT!

Maybe YOU should be helping Yahiko with his D&D character

BTW, do you have proof that it is only electrically conductive under high pressure? Since it is 96% silver, I would assume it would conduct electricity quite well.

When I changed my FOP-32 HSF to Volcano 6Cu in my A7V133, artic silver was all over my chip and it didn't cause any trouble at all.
I also found this <A HREF="http://www.coolerguys.com/cpucool/compounds.shtml" target="_new">info</A> at <A HREF="http://www.coolerguys.com" target="_new">CoolerGuys</A>
>>Negligible electrical conductivity.
Arctic Silver Thermal Adhesive was formulated to conduct heat, not electricity.<<

:smile: Good or Bad have no meaning at all, depends on what your point of view is.

Anyone know what "micronized" silver is? That might be the difference that I don't know about.

Sounds to me like silver that's been ground to micron-sized particles.

Arctic silver is small silver particles coated in dialectric grease, I read off of arcitic silvers website about the pressure, I presume under pressure is squeezes the as together causing conductance.

You shout at me when I have given some completely harmles miss info.
I just tried to help the guy and keep it all on the safe side,trying to avoid any BS 'advices' that plague this forum.
BTW where were you when the guy asked for help?Busy at trolling as usual?

Reply to Era

No no no, I wasnt yelling at you, That was the myth slayer of justice, I did not mean to yell at you and I apologize.

PS: I take offence to the trolling comment, seeing as I was right behind you to offer advice to this poor soul whos burning smell is most likely his psu.

Also, I had seen that harmless bit of misinfo around the forums for a while, just felt like it was the perfect time to clear it up, again I apologize for appearing to yell at you, but I was not trying to yell at you.

It was fats,not you who suggested the psu!
If it's the case of the psu,that makes me the bullshitter.Oh well.

Reply to Era

hmm.. From my experience new computers ussually smell really bad the first couple of days you have them (I'm not kidding, I'm sure other people have noticed that too) but if it's just the chip that's new it might be a problem if things are stinky!

I understand.thanks for the reply.

The troll remark was unfear.I'm Sorry.But sometimes you make so provocative statements that it's rather hard to take you seriously.
Anyway I kinda like your style.Even in the worst cases you are fun to read.

Reply to Era

I dont make really provocative statements, I just debate points vigerously.

I have 1600+ posts and they ALL came from cpu and video forum and most of them are trying to help others with issues or debating technology. I just try to help where I can, and give advice or commentary where appropriate.

I have read many of your posts where yuo help people and give advice.
By saying you are sometimes provocative I didn't mean you behave like meltdown or fugger.no no.
Provocation can also stir up a healty and productive debeat.(cleaning the air for one).

I think thg forums are in all a big mess,but I like it that way.

Well I put on some new thermal paste, I couldn't get the arctic silver stuff, and now the temp is up around 56-57. This is hotter than before, although for some reason, the smell isn't quite as bad. What is a safe temp for the CPU? I am using an AMD approved Cooler Master fan, and the RPMs are in the 6000 range. I was thinking maybe I need a more powerful fan, I was thinking about getting an Antec jet cooled CPU fan, but I don't see it on AMDs approved list, has anyone tried this fan, and with what results.

Also, I should mention, that the CPU only runs that hot under stress, you know after some 3D gaming, it usually idols around 53 or 54.

Thanks again for all the advice.

Derek
