Now, this might only be an effect of more extreme overclocks, but it demonstrates a fault in the quality control of the Foxconn LGA1156 sockets.

Thought I'd point it out, might be of interest.

was just going to post this. Shows what happens when bunny rabbits play with electricity

Aye.

For those not into reading long threads, this boils down to bad contact within the LGA socket for any LGA1156 chips... exacerbated by the fact that Core i5 draws as much power (in amps) as Core i7, but i7 has extra pins to draw the current through. When contact is bad with some of the 175 current pins in the 1156 socket, the other pins are overloaded and result in melting the socket and burning the pads off the CPU.

Worst thing about it is, if you did hit a 'high current on pins due to bad contact' scenario under normal usage (which could, in theory, be perfectly possible looking at the terrible pin/pad contact in that Anandtech example) the warranty on both CPU and motherboard is invalid because it only happens in 'extreme' scenarios... and you'd be hard pushed to prove you didn't overclock.

Foxconn fail.

But then, I already knew that from my Blackops board... a support site that 'will be back soon'... pfft... and a copper northbridge block designed for watercooling that comes with an aluminium top... galvanic corrosion much?

Foxconn fail.

Quite possibly. I also think they are complacent because they believe they have the whole market taken.

Its a good illustration of what crap quality connections can do actually, it would be like running a house of a 3x 1.5mm T&E cable :P

Christ, that was one of the options I looked at as well !

This is a pretty big failure ... and just recently I was saying nice things about Foxconn ...

That's why i never buy first generations of pretty much anything.

that's probably a very wise move +1000 ;)

LGA is anything but 'first gen' now. :) It's just Foxconn getting sloppy with their socket QA. Because made no mistake - just about every LGA socket out there is made by Foxconn.

really ???

I didn't know that ! :shock:

Foxconn made every single LGA775 socket, AFAIK, and most of the LGA1366 ones. I'm not so sure about the ZIF sockets that aren't LGA. Also AFAIK, they've lost their apparent 'exclusivity'... other companies now make them also.
