Should I even bother putting this in my board to test it?

What is the story on the chip?

If you value your mobo you won't apply a voltage to that thing, PCB is cracked right?

Bought second hand (ebay), supposedly "tested to be fully functional". That's a nice gouge you see there that was never listed in the description.

 

[Idontcare]

I see two gouges, one on the left perimeter and one in the middle of the pads on the right hand side.

How do you even gouge a PCB like that? I can't figure out what they did, unless they dropped it?

Or he dropped a knife on it. That gouge looks pretty bad.

 

[fleshconsumed]

I would try and return it. That looks bad and I'd be afraid it would fry my motherboard.

 

[Gillbot]

Return for refund.

 

[kmmatney]

Well - I'd probably try it. I don't think you'd harm anything. I think most of the connection are power connections, with a lot of redundancy. It doesn't look like any connections are shorted, so I don't think you'd damage anything trying it.

This.

I take it neither of you have damaged one of the pins in an LGA socket mobo? It is very easy to do, and once bent they are so tiny it is near impossible to bend them back into position. (I've tried)

I would not put that CPU into a LGA socket and risk it snagging and bending a pin. Not for $100 would I risk it (unless the mobo costs less than $100 )

If I had a land diagram and could verify that the affected pins were just redundant VDDC pins and not DDR data channels (remember, LGA2011 - there's 4 of them, so there's a lot more pins devoted to the RAM controller) or something else important... or that there's no pad-smear in that gouge shorting out the pins. I'm not going to take a $250 motherboard and give it a whirl.

And then there's this. What's the first thing a mobo maker looks at when they get a board in for RMA? What's the #1 reason RMA's are denied? It's a deep gouge, I wouldn't be surprised if it bent a pin or two out of place.

Contacted the seller already, he's pretty accommodating. Back it goes, and back I go shopping for a new CPU. Unfortunately it means probably another 2 or 3 weeks of waiting to be able to move to LGA2011.

I fail to see how the seller didn't know that the chip was damaged. I take it there is no way the damage could have been caused in transit, i.e the CPU was packaged properly.

 

[GPz1100]

A good seller would have pics of the physical item they're selling, and something like a cpu would hopefully have a top and bottom view included.

I know when I list something, I tend to go overboard with pics (should see the listing for my motorcycle boots - at least 12 or 15 pics showing different angles, the soles, etc..)

Nope. It was packed well (well enough at least) and there was no physical damage to the packaging. The listing was explicit about a couple of very minor scratches to the IHS and the pics were specifically of the top of the chip. Absolutely nothing was said about the bottom of the chip in the listing. Only thing said was "Tested fully functional." Whether the damage was done on removal after said testing, or whatnot, who knows. All I know is I'm out my time + return shipping. Not a total loss, but an annoyance for sure.

Yellow flags prior to purchase to be sure, but nothing overly unusual either.

In hindsight though, definitely suspicious. :hmm:

Not to mention if you load that chip up and it needs one of those pads, it could end up melting one of the LGA pins. Not worth the risk.

Not that it matters now, but intel does have detail diagrams in their data sheets about what the pinouts are.

I would still not install it myself either, and would do what you did

 

[SunnyD]

Just a quick update - quality eBay seller. I dropped the chip off in the mail yesterday and forwarded him a response with a tracking number, which he replied and went ahead and refunded me already and apologized. It could have been worse I guess.

I'm guessing that's how he got the chip or the chip looked after it had been pulled from a working machine (due to own error?) and nothing was thought of it. Some eBay (re)sellers simply don't know the difference. I'll give him the benefit of the doubt on this one.

 

[fixbsod]

I thought some of the more specific diagrams are actually (gasp) confidential ?

[mikeymikec]

I think it takes skill to maim a processor that doesn't have any fragile sticky-outy bits like the processor pins of almost-yesteryear

 

[Dahak]

Probably for some aspects, bit the pinouts are public, for example datasheet vol 1 has the pinouts on page 94 (here)

But I probably would not want to try to as many as this one had, maybe for 1 or 2 pads but

 

[SunnyD]

Well, after looking at a few references (you have to look at the mechanical reference guide to get the landing labels to match up with the landing reference in the data sheet):

(the deep gouge in the middle)
one pin is reserved
one pin is a ground pin
one pin is a DDR0_MA line

(the "smear" on the left side)
both pins on the side are DDR3_DQ lines

So odds are even if there were no shorts on the socket thanks to the damage (reserved pin and ground pin aren't likely to do any damage), I would probably have had memory issues right off the bat since DDR0 is affected (that particular pad is pretty much obliterated and would probably never make contact with the socket), and the system wouldn't have been stable at all. I doubt it would have even booted Windows, let alone make it past POST.

So it couldn't possibly have tested 'working' in the item desc could it. I think the seller must've just gave it a look over after taking the item from someone else and just took their word for it that it was tested.

 

[Vinwiesel]

"Tested Working" is a pretty loose term. Even with the damage it could be at least partially functional as long as none of the affected pins were critical. Maybe all the seller did was check that it boots to bios, or the damaged pins are for the igpu or some other unused portion.

 

[BD231]

The only way to know for sure is put it in and test it.
