P55-UD6 socket burn

[Erklat]

I believe you shouldn't have any problems.
First,it seems that occurs in extreme conditions when vCore is pumped up and CPU starts to drain a lot of
power - the ammount your wife is not likely going to achieve.
Second,I truly believe that actually one or two out of ten (or even more) boards sold really burns.
But most of people like to be on the safe side.

How many burned sockets have you seen with daily (ab)usage with mild OC's ? How many run rigs here at stock speeds ? How many have reported real damage (not some marks on the CPU contacts) All stability issues are now related to the bad socket, pin contact...there's more to that guys......Snowball effect in maximum motion !..... If it was such an issue there would have been more than a thousand RMA's already solely from Gb mobo's... have you seen any or even heard from them ?

More damage detected

crappy ASUS M3F (made at 27 week 2009), with Xeon 3470 after 20-50 hours of usage under deep subzero (-50 to -100°C) on CPU got first alarm bells

CGC_TP_NCTF pin from socket burnout, and same melt parts on CPU . According to intel datasheet that's not critical to function pin, for debug usage only. Few VCC pads on cpu melted and got bumps into CPU PCB substrate.

Rig still working.

great pics TIN

Just above the ones with the blue arrows it appears there is a slight bit more plastic melting from the upward pointing piece of metal from a few of those pins (the piece of metal level with the plastic, not the pin).

Well, I gave up the Core i5!

I bought parts for my new system, and a week later, began to appreciate these issues. They were more than 3 weeks stucked in my office.

Sold my P7P55D Deluxe + i5 750 this week and bought Asus Rampage II GENE i7 + D0.

Really is a shame that the Intel/Foxconn/Lotes, or whoever else has "guilt" in the development of this project, are playing so dirty with their customers, consumers.

Shame!

[saaya]

nice pics tin eof!
are those metal parts next to the pins the lower end of the pins burned 90C? how come they melt and the pins actually dont?

I put together a system for the Wife using this same motherboard. She play's most of the "heavier" games, GTA4, Crysis, etc.

lol, nice wife

I tried tell you guy's a few posts back that those burned posts (blue arrows) make contact with the cpu once installed. Look at the very outside row of pins in the socket, all the pins bend inwards leaving nothing to contact the outside edge of pads on the cpu. Those posts make the marks in the cpu other wise there would be no marks on the outside edge pads all the way around the cpu.

Now look at the 2nd pic of TiN_EOF (the cpu) all the way to the bottom left you see a indentation in the pcb of the cpu and not a pad, if you look very close it looks like it's making contact with the pad in the next row directly in front of it.

Any1 trying to help the motherboard makers solve this issue should have them start looking into the composition of the pins in the socket and a thickness check just a slight variation would drastically change the amount available current draw. It wouldn't be the 1st time poor quality products caused havoc in the electronics market. every1 remember the capacitor issues of years past.

I dont think those posts make contact to the CPU landing pads cowpuppy. It would be blatantly poor contact pressure..

[FireDragon]

It would seem that the problem is lower in the socket itself as the socket seems to take the worst of it and CPU's pads dont seem a burnt as they should b if that was the actual area where there was poor contact, if u look at those pics the tips of the pins r not discolored at all which u would expect from that kind of heat, the fact of the cpu's r not burnt as bad as the pins so that would also lead me to think it ISNT the connection from the cpu to the socket but lower in the socket when u r appy to much pressure in some way, maybe the socket itself is bending enough with high mounting pressure that it is alow somekind of contact inside the socket itself, that is just my .2

Also if u look the pins that r burnt r burnt down very low in the socket where there is the least amount of resistence threw it so this also leads me to believe it is in the socket itself and the burnt pads r the result of the heat traveling threw the pin into the cpu pad, but who knows?

Holy sh**.
I was just planning on building a new computer and I learnt about this only two days before ordering cpu and mobo. I'm still on time to switch again to AMD.

Is the problem solved?
Does the LOTES latch solve the problem?

[jmke]

unless you plan to cool with dry ice, LN2, phase change and want to overvolt the CPU, I wouldn't worry about this issue
and even in those cases, recent revisions have no more issues with the socket...

Or they watercool and plan to run sustained overclocks under 24/7 loads. Always going to be old stock out there, and doesn't lend any votes of confidence for Foxconn's "revised" sockets either.

Seen a enough reports of users with memory issues to wonder how many might be from bad CPU pin contact. Very easy to simply blame the kit as bad, yet some people have gone through several...

[Stefan Payne]

Is the problem solved?

No one really knows, that's the problem.

I've even heard of some instand burned sockets.

They put the system together, tried to boot it up and than it burns, bevore it could even post.

I don't know why that happens but i sure want to know....

[Dahaka]

EVGA P55 FTW over here with the same F * C K * N G problem, probably is all ready dead.

Pictures later when my friend send to me.

[Erklat]

Damn, almost imported eVGA P55 FTW considering it was imune to this issue.

[Mafio]

I've an msi p55-gd60 with foxconn socket, after 20+ hours on LN2 and SS the socket and the cpu are still alive.
vcore was always over 1.55 volt and vtt was always over 1.5 volt but none of the pin is burned.

maybe I was lucky

Nah, the burn was RARE, not mainstream...

Several users has ran several hours 1.65-1.7vcore and 1.7-1.9vtt...
In fact, even on air, I havent been down to 1.5VTT yet.. 1.54v is lowest I have used so far....

[tiborrr]

Here's the P55A-UD3 i obtained. Looks like it uses a complete LOTES socket:

[chew*]

Nah the socket is foxconn and mount plate front and back is lotes, but it doesn't matter. I have yet to burn a socket out on any of the new boards and yet to see someone post it.

[westsider]

same problem with dfi x58-t3eh8
foxconn socket too

and 3 different boards got this problem even without subzero

the first feeling was like a....hey i didnt clock it
what the hell
and after that i already realised this board must have some problem
because i mounted the cpu and never unmounted it
the first time i unmoented ,i see the pins are so fu&/% up like a cut thm with knife

[devil_mcry]

hi,i must return back my p55a ud5 for rma problems

however after the remove cpu, i looked the back side and... lotes clip didn't solving the
problem

my cpu has many "pin" not signed...

[TiN_]

Photos please.

same problem with dfi x58-t3eh8
foxconn socket too

X58? 1366? How can it be?

[Leeghoofd]

Snowbal effect Tin_EOF... now everybody starts looking at pin marks,luckily for me my eyes are so old, that I don't see one pin marking on my I7 CPU's lol

[devil_mcry]

not burned my cpu, but not all pin are checked

however i haven't digital camera (is damaged) and with cell is impossible...

[TiN_]

Hate to report to this thread, but I must.

As you remember from my previous post - ASUS MAXIMUS III Formula has Foxconn and affected too.

History have now bad update with continues. Tested yesterday this combo with 8800GTX. both GPU and CPU was under LN2, CPU temps never go above -50.

CPU was clocked at ~5G, only 1.57 V and lower by DMM reading, and with two cores disables. No HT too. LLC was on. And after 6 hrs of good ocing, i've shut rig off and putoff pot and cpu...and...pics in attachment.


After clean up, straitning pins under binocular microscope, i've put CPU to mobo and rig worked. No more overclock now.

Will never go ASUS from now. Yes, I know, it's foxconn issue, but tired of bullshift marketing of stupid top mobos with idiotic engineering..
