Burnt CPU looks like...?

[RoyalTenenbaum]

Hello,

Just wondering because I've never seen one, but whats a fried CPU look like? My CPU has some of the black thermal square on it from the heatsink (intel cpu, intel board), but I would assume thats okay.

Thanks

thats from the thermal pad

its fine...look on the underside, if its fried i'd guess it'll look blackened

You'd see scorch marks around some of the pins, and proabably on the CPU socket not the motherboard as well.

If it's just the thermal pad, your chip is fine.

Mine looked perfectly normal...as if it hadn't even burned up.
...but the Duron she never booted no more.

Never mind, I see his neffing comments all over now. An "L" user, obviously.

And BTW, Demon-Xanth, I'm about halfway through the series again, just finished Heaven Cent.

I have a burned up Duron 800 right here...not even a tiny scorch mark...

I fried a 2200+. Looked normal, but I was able to smell when it went (I was stoopid and didnt plug in my HSF properly). I think it depends on how you fried it, but more often than not I should think you'd have to have done some serious frying to get a chip that looks like it's been fried.

Mine was an 800, too!

Burned up or just shorted out? There's a difference.

I have only seen a chip with actual visual clues once. It was a long time ago and I believe the chip was a 486 or roughly around that time frame anyway. I worked in a computer shop and one of the other techs installed a chip incorrectly. I think he put it in 90 degrees off from the correct pin alignment. It actually made a super fine crack in the chip when it blew. I wasn't in the room at the time so I only saw the aftermath.

 

[RoyalTenenbaum]

how was it put in 90 degrees the wrong way? will it even fit like that? i know it won't work like that, but do the pins match up?

I have one that I'm not sure if its burnt or not, but there's a small bump on the bottom

 

[spoondigity]

Whatever he was using it fit or he made it fit well enough. I just remember walking in and him freaking out that he was going to get in trouble. I know he said he didn't get it oriented in the right direction and I think he said it was 90 degrees off. I have no idea exactly what chip it was he was using for sure but it was a socket. We dealt with intel, amd, and even cyrix chips at the time. It also could have been on an adapter. I only got to see the hairline crack in the chip.

Anything will fit with enough force...

How do most CPUs get cracked? I know the heatsink is really securely clasped onto it, but how hard does it touch it? I mean, do some people push down on the heatsink or something and it cracks?

"The die of your Socket A processor is made of silicon, which is glass. It is quite fragile. Careless installation or removal of a heatsink can lead to physical damage such as edge chipping, cracks, etc. Physically damaged processors are not replaceable. Use extreme care when mounting and unmounting the heatsink/fan assembly! Especially, never place any pressure on the top of the assembly as this might crush the die.

The smallest chip or crack in the CPU's die can render the CPU inoperable. While it might operate for awhile, it will probably become unstable during use or fail altogether sometime down the road"

Take a look at this, quite funny when you see some of the images regarding installing cpu's LOL
AMD cpu

 

[RoyalTenenbaum]

i have an intel board and cpu, so i think its different from how an AMD cpu and board are, right? i think the AMD cpus have that little glass square in the middle, but intel's dont'. yeah?

Fried a 1ghz tbird (ayhjar ) before I could even test it. No visable marks accept a fine crack down the ceramic of the cpu.

I did that once, putting a 3.3v DX4 into a 5v socket1 motherboard. There was a pop, a sizzle, and the CPU actually partially melted into the socket. When I finally pried it apart, one of the holes on the socket was solid black and the pin was discolored. It actually cracked all the way through the ceramic, and I had a really interesting-looking 2-piece DX4

Hey, I ended up with that motherboard, I swear (and I still have it)! The funny part is that it still worked just fine with the proper cpu!

That "little glass square" on an Athlon (or rectangle nowadays) is the actual CPU core. Intel's CPU cores are covered by by an intergrated heat spreader.
