LGA 1155 Socket Burn: here we go again

[SubZero.it]

Last year, credible reports of a design defect with LGA1156 sockets made by a certain component manufacturer in particular, made headlines. Reviewers found that extreme overclocking using increase voltages, in test cases, caused certain pins of the socket to burn out, damaging both the board and processor. The defect was found to be caused by shorting between the pins and the socket causing tiny electrical arcs. Motherboard reviewer from TechReaction.net discovered that his Gigabyte GA-P67A-UD4 and GA-P67A-UD7 samples showed signs of socket burn. The publication is yet to receive a reply from the board manufacturer.

LGA1155 and LGA1156 are very similar in physical pin layout, chip package, and retention clips, although the pin-maps are significantly different. TechReaction comments that while only "extreme conditions" cause such pin burnouts, 24/7-stable overclocked settings could, over a period of time, create similar conditions. Only time, and extensive testing will reveal if burnouts are a cause for concern to enthusiasts.

Now have got my fingers crossed!

[Origin_Unknown]

i wonder how many volt's they where using on the OC

[quake6]

There is thread about that... He got it like that from Gigabyte, but again I doubt they used 1.6 - 1.7v

[Sly Fox]

Just now waiting for my UD5 to arrive, and suddenly my OCD is kicking in like crazy.

This is going to drive me insane lol.

Let's hope it's an isolated incident.

[zalbard]

This is a major let down if it keeps going on for yet another socket.
Bet this will put off a lot of enthusiasts.

Wonder why everytime are gigabyte boards emerging in that

[Bojamijams]

Lol @ gigabyte fanboys once they see this thread

[PatRaceTin]

Foxconn again????

whaaaaaaaaaaaaaa how about my UD7@!!!!

[RSC]

I sincerely hope this is an isolated case, as it seems.

[Andrea deluxe]

how many volt??

1.6? ok...

1.4? not ok...

[FischOderAal]

I think it's more a problem of the current than the volts Looks to me as if they heated up too much. An indication for this is the discolouration.

[Dami3n]

There is no solution, is a curse for their "socket madness" strategy

agreed

higher voltage dosnt burn away metal, higher current which turns into higher temps does.

[Andrea deluxe]

Wich mainbord on store(review mobo is not the same) have lotes socket?

[Chrono Detector]

Great, Gigabyte really needs to get their together, or was it Foxconn or whoever is responsible for this mess really needs to shoot themselves for creating another disaster. First it was P55 boards and they have carried the exact same issue to P67, what a joke. I just invested in a P67 setup myself and I'm not happy to hear this.

[Chri$ch]

And what is if it isn´t a socket problem?

I have not used the board at all....I received it in this condition from Gigabyte. My M4E and UD7 are also Foxconn sockets, and have had heavy use without any issues

maybe a production failure and bad quality check @ gigabyte..

the PINs are 1 VCCIO and 3 VSS.

[Buckeye]

My UD4 has shown no sign of this problem <yet>
And none of my P55 boards had this either.

Trying to remember but with the P55 sockets didn't this problem happen to other manufacturers motherboards also and was not limited to Gigabyte ?

[BlueAqua]

Let's not blow this out of proportion yet, it's only been seen on 2 motherboards by the same guy, not a widespread issue. Before everyone attacks Gigabyte with their pitchforks in hand why don't we wait to see if this is a real problem or just an isolated incident.

[Loque]

socket can't take that many awesome gigahurts

Agreed..
Now I don't push my systems to the degree some of you Xtreme people do but I've benched the Intel board with 1.525vcore up to 5088MHz and seen no issues.
What I'd like to know is what voltages with what cooling this guy was using when this happenned.

[JH_man]

Isnt it a bit early to go bananas over this? It may just be a single incident, and may be related to other reasons...

The defect was found to be caused by shorting between the pins and the socket causing tiny electrical arcs.

For the sake of accuracy, let's just get this straight: This is not the reason because "shorting between the pins" didn't happen. That's absurd. What would happen here is that excessive current would have indirectly caused some pins to overheat. Heat is the product of power dissipating in a material due to its resistance versus how much voltage is being applied (which determines how much current there is). The first thing to know is that physical contact points like that in any connector are high resistance joints versus plain metal (wire, pins, etc). The comparatively higher resistance causes more power to be dissipated at that contact point that in the lower part of the pin. This is further complicated by higher temperatures increasing the resistance of the metal. As either voltage is increased or resistance of the load is decreased (when the CPU is doing more work), more current flows. This causes increased heating proportional to each link in the chain's resistance provided the voltage is constant. In this particular case, the high resistance mechanical junction was the first to fail. More heat was being dissipated than the metal could handle and it essentially melted.

This same effect can be found on connections that are dirty but otherwise normal, such as extension cords. Dirty plugs make for hotter connections. If it gets bad enough, things will eventually burn up. This is also the reason why you have to select a wire that's big enough to handle the amount of current you intend to transfer across it instead of just using the same size of wire for everything from cell phone chargers to car engine starters. The metal has a little bit of resistance to it and you must select a conductor that will not overheat. This is also why you must use a bigger aluminum wire than you would a copper wire. Aluminum has more resistance per distance unit per cross-sectional unit, so it heats more for a given size and distance. If a metal had literally no resistance, you could quite literally use a hair-sized wire to power a city.

Going banana over every single incident is what people do on these forums nowadays, heh

Glad i've yet to of made any upgrade moves for a few years!!!

Surly if the pin is touching the pad on the CPU there should be no problem, but clearly it's not for it to ARC. However is it due to the high voltage, well more amp and poor socket pin material at fault
