Why would the MCH chip explode?

Anyone know why the chip marked FW82801EB [I think its the MCH] on 2 AB60N motherboards, on 2 totally separate systems in 2 different apartments would just suddenly develop a microscopic hole and start leaking fluid? Not to mention the awful electrical smell that accompanied it?

One system was a stock P4 2.4B no overclock running very tame settings, the other was a P4Prescott 2.4A running 3GHz with regular settings.

The first board had the CPU voltage on AUTO while the second was pumping 1.4V to the Prescott. RAM voltage was on Auto. The first board died back in April and was sent back to Newegg since it happenned within the refund period. This motherboard lasted less than 2 weeks and died yesterday. Both were listed as refurbs, but came sealed and had all the accessories.

What would cause that chipset to just burn up out of nowhere? Both Power supplies are decent quality [one is a cooler master 350W the other a 450W RaidMax] and are still in new condition...

I googled my ass off but cant find anything that can give me a remote idea on wtf happenned. 😕
 
with the stock 2.4b there's no good explenation. As for the prescott, the motherboard only supports prescott up to 2.8Ghz, so perhaps the 3.0ghz overclock killed it. Perhaps you should avoid refurbed motherboards in the future..
 
I sent it back for rma already, I should have taken pics. It was the chip marked Intel, the southbridge chip. Just smoked up.

Click to expand...

As for refurbs, I purchased quite a few refurbs from Newegg, and these two mobos were the only thing that messed up. 🙂
 
K, I stole this pic from hothardware.com and this is a pic of the chip that exploded on both mobos. I want to track the problem down cuz I just laid down cash for an ABIT AI7 and want to make sure its not me doing anything. LOL.

The one marked Intel... LOL
 
Yeah, thats definatly the southbridge. By the way raidmax PSU's are definatly NOT good PSU's, and have been known to cause lots of problems Was there any standoffs where they weren't supposed to be shorting out the motherboard? Very strange that the southbridge would blow.
 
The other system was connected to a pretty new Coolermaster PSU, and this RAIDMAX, while not the best, has served me well. through 2 AMD systems and 1 P4 system. No studs in the way. I cannot figure it out for my life. Must just be a fluke. Ah well, I used the opportunity to pick up an ABIT AI7. Should eat that old shuttle board for toast. 🙂
 
Just to keep folks informed, I have had 3 of these chips do the same thing. All of them are/were in Dell Optiplex GX270 boards. I'm thinking a bad run of chips.
 
Wasn't their a story about some bad intel chips? Not sure if it was these or some other ones. Caused some production delays. BUt I think it was the 915/925 models not sure though.
