Can processor fry mobo?

I've got 3 AMD processors and 2 mobo's from upgrades gone south.

I've finally gotten my "test" box up and running (semperon 2400, 256 mb, soyo mobo) and can finally test components (HD, memory, video, etc.) without tearing my other machines apart.

The unknown's won't work in any combination. Could any of the 3 unknown processors be fried enough to ruin my now working soyo mobo? I'd hate to throw away a good processor, but don't want to fry another mobo either. Is there somewhere that the processors can be sent without costing an arm and a leg?

Thanks in advance!

 

Although it is unlikely unless the fan is failing on the CPU, it is possible for a CPU to fry a mobo. Main causes of this in the past was incorrect voltage settings. But most mobos are auto voltage these days anyway. I dont like AMD CPUs at all personally, and as an OEM we had a high failure rate on these until we stopped using them. They cost half as much and are half as reliable as intel CPUs, even though the speeds are as good. You get what you pay for.

These days the old AMD CPUs are likely to be worth a fraction of your mobo, so i wouldnt risk trying them on your good mobo. Sad but they may just be useless now, unless you donate them to a tech, or come across a very cheap or free working mobo for them later. I have a drawer with 30 + Intel CPUs and 20 AMDs that are all useless now as i cant get mobos for them, so i understand feeling like its a waste of hardware.

 

Personally, I'd take exception with the reliabilty opinion you've voiced and I have yet to hear, read or learn of any FMR data or any other data that would support this kind of statement. However, you are certainly entiled to your opinion and I would tend to agree with most of the rest of what you said while making one observation. As to Intel - I don't think one gets what they pay for compared to any Athlon. K-6's yes, but thats like referencing ancient history in terms of geek speak. The important point - lets recognize this for what it is - an opinion.

Now, as to the unrecognizable CPU's - Fitzincc - get yourself a good magnifying glass and save yourself a lot of time and effort. There's no need to plug in your AMD CPU's in order to identify them.

 

No magnifying glass needed, I have 2 xp2600's and one Duron 1600. All components are less than 2 years old. I'm fairly certain the mobo's are fried but not so sure about the processors. The mobo's are newer style and have auto sense for the cpu's. Any combination of them exhibit the same, no video, no post, no beep, all fans run. The processors are not damaged because of no cooling fan, ESD perhaps (got a little careless doing my own personal upgrade!).

 

Doubtful re: the CPU's

 

Check your warranties as most of the mobos we sell have 2 years warranty!

 

I was helping someone on another forum. Same thing except that he put the CPU into 2 of his friends computers. Not only did he have to replace his own mobo, but those of his friends as well (although you are up to No 3 too ).

It would be good if you could get warranty.

It might be doubtful that all three CPUs are frying mobos, but I would not trust to put any of them into a brand new one. Try to retrace your steps and identify which one may be causing the "frying ". See if you can get a cheap mobo (Ebay?) to try the possible good ones.

Have you reset the CMOS on those boards?

Have you ruled out the motherboard shorting to earth? (try running with mobo outside the case on a sheet of cardboard).

Thanks for the input everyone. Guess I'll wait until I see a mobo on e-Bay.

 

One thing to watch would be the power supply in your case, if you are frying mobos, maybe the ps is playing up. Also get some good surge protection at your pwer point, like a surge protected power board. not the $5 ones either, they are pointless.
