uh oh, burnt up cpu?

[x_dreams]

just bought a xp 2100 and a gigabyte 7vaxp mb. along with the cpu came a volcano 5. unknown to me at the time, the volcano 5 is not rated to cool the 2100. anyway, plugged everything up and pc boots for around 7-8 secs then shuts off. tried it without the heatsink/fan and got the same results. u guys think my cpu may be gone now or what? all help is appreciated!!!!

AMD says you can use the 5 but it seems very boarderline to me.Basically anything over a 1.3 I would not use it. it's hard to say did it ever fire up for any length of time other than 3-8 sec.? If it won't even start post? then i would say by by to the processor any way you can try it on another board? Or try a different processor on this board?

I would also argue the fact with the people you bought it from that the Valcano 5 shouldn't be used on a processor over 1.3? Was this a package deal or did YOU pick the heatsink?

Yikes! Be careful, or you'll burn it up for sure! :p

On a lighter note, you may have a problem with something else rather than your processor at this point. Seems like it would run a little longer than that even with the fan/heatsink you have before it decides to shutdown.
Possibly motherboard or power supply related problems? I would try booting up with just the 'basics' (less draw on the PSU) and see what happens. Could be a short againsed the case somewhere too causing the power supply to shut down.

I agree... it seems that you have a problem, but a burned up CPU doesn't seem to be it. Post back with more details and we can help with the problem solving. Did it beep for POST? Did anything show up on the monitor? Did you smell anything burning? Did you check to make sure the CMOS clear jumper is on the right pins? And so on.....

Well unless the newest XPs do something different from this report (http://www.geek.com/news/geeknews/2001oct/bch20011029008570.htm), I guess x_dreams is gone shopping today.

[jabarnutcase]

Yes..The same quote alarmed me too. :eek:

Kind of a shame x_dreams tried that experiment. He may have still been shopping, but possibly not for a new processor! :rolleyes:

[boneburner]

firing up the CPU w/o a heatsink will fry 50% of newer processors nearly instantly, the rest within seconds. May not have been a CPU problem before, but it is now! YIKES :eek:

[Budfred]

It only would have fried the CPU if the CPU was actually getting powered up. I suspect that it never got that far. I have a P4 that wasn't working and I tried it without the heatsink to see if it even got warm, but not go. I got another mobo, installed it with heatsink and it is working just fine.

So what is the story x_dreams, do you have a nice piece of cyber jewelry or is there still a chance you have a working CPU???:confused:

[boneburner]

I would not recommend powering a CPU w/o HS EVER. The risk is too great and the benfits are nonexistant. One can easily detect heat from a powered CPU with the heatsink in place(liquid-cooled systems being the exception). Even if it does not fry the cpu, the intense, unmitigated heat will cause some insulation degradation, setting you up for future CPU failure or decreased thermal efficiencies(read: hot spots in the core).:(

[Budfred]

Very true, if the CPU is getting powered. When I did it on my P4, I figured the CPU was dead already and I was in learning mode anyway. Since the mobo was dead and the CPU wasn't getting powered, it didn't hurt it at all. I did try feeling for heat with the heatsink/fan installed several times before I tried without and I normally also would NOT recommend running without the heatsink/fan in place. My main point here is that x_dreams may not have fried his CPU if it wasn't getting powered anyway.... If it was powered, it is almost certainly time to go shopping.

Sorry, case of clumsy-finger-double-post. :)

P3's and P4's behave very differently than AMD chips when run without a heatsink. Follow the link I gave and read the story behind it. You'll see that without a heatsink a P4 clocks down, while an AMD burns...

[jabarnutcase]

Yes, getting back to x_dreams somewhat brief original description of his problem, if he is in fact CPU shopping, I suspect his fun is just beginning.

I still have a feeling he has another problem besides! (And that the CPU wasn't the original problem) although it may very well be one of them now. :eek: (Especially being a hotheaded AMD...Which I use myself :))

Fill us in when you can x_dreams!....Man, I hate "unsolved mysteries!" :rolleyes:

(Edit) woops...Snuck that in there just before mine SD :D
(Edit #2)Sorry, can't help it...In reading his post over again, he said it "boots up" for 7 to 8 seconds. Sounds like maybe the CPU was getting power long enough to....Well, you know. :(

[x_dreams]

sorry for the delay, been really busy. i put the chip into a friends mb and the same thing happened, 3-8 secs and nothing. i also tried to boot it up with the "bare" essentials and nothing helping out there. the ps is one that came with the case, tiger pro or something like that. i guess it was really, really stupid to fire it up without the heatsink but i was thinking that it would at least post before cutting off but i get absolutely no beeps or anything. no burning smell or anything to make me think it is burnt up already is present. the fans on both the cpu and the chipset both worked for the few seconds power was available. i was thinking maybe the new wd harddrive had something to do with it but ruled that out quickly. i am waiting on a volcano 9 to come in the mail before attempting anything else with it. u guys think the ps is garbage? thanks for all the help so far.

pretty much puts it to rest.

[jabarnutcase]

We're not sure, but we sure think the CPU is! :eek: :(

Like YODA said, short and to the point. Think about it. If the exact same thing happened when you put the CPU in a friends computer...(By the way, you have a good friend there), the CPU must be shot.

It may be internally shorted causing the PSU to shut down. (Is that what you meant? That your friends computer which was running perfectly shut down when you put your CPU in it?)

Yea, I'd say "pretty much puts it to rest" too.

[Budfred]

We are gathered here in the sight of Bill Gates to pay last respects to this prematurely departed CPU. It never really had a chance to experience a computer life, but it has gone to a better silicon heaven. Let us program, Amen.:p :D

Time to contact the vendor about a possible RMA (return merchandise authorization). Good luck...

[x_dreams]

guess i should get on the phone and see what i can do. man, ut2003 will just have to wait a little while longer........ :(

in heatsinks we trust!!!!

thanks for everyones help

[jabarnutcase]

Good luck x_dreams-

One last thing...In looking back on this thread, something occurred to me- (And you never really told us), but can I assume that when you bought your Motherboard and CPU that they came separately and you installed the CPU and Heatsink/Fan?

The reason I ask, is that when it comes time to install the new one, do a search here or we can help you.
It is very critical that the heatsink/fan assembly mate perfectly with the surface of the CPU along with some other preparations.

There are some excellent threads/posts here on how to achieve that.

I am beginning to think that you're nice brand new XP2100 had a VERY short life after you installed it, due possibly to the fact that the heatsink was not installed correctly to begin with.

Like all of us, live and learn....Again, check back when the time comes and people will be glad to help. :)
