Wow so agressive community ;D

this come from a multi rig GPU mining, mounted rack with 2xSupermicro-X10Drl-i and 2xAsus-Z10PA-D8 24 GPUs but thanks for alerting about my stupidity or nob answer like "it's not clean", no dude it's burned from core to pin...
Just for Infos (only) it happens on this system fully watercooled, including Gpu's (yeahh...i live high in the mountain!) with a bad OC of a non corresponding GPU BIOS (technically not me a soft miss understood my remote command)...
1 tube was too close from the back of this god damn Vega with fire to the ass, tube (flex one) brake mix of high quality coolant from IT industry and an "homemade mix of electronic/eletcric transformer coolant also fully dielectric get every where on the MB in relative quantities; thanks to security valve.

My think; coolant dry between socket and cpu, then became non-dielectric and solid; melting some plastic with first "green skin" from the outside to the core with core heating too because of computing too but to the outside=too hot

My question was, assuming this "green skin" is only protective and copper pad seems to be in fact all linked electrically speaking so going optimist and would say it's ok....but deep inside i know it's dead and i cant go further with this kind of "scar cpu"

My apologize for being and stupid and dirty for your eyes to not rip off my cpu just too ask a more....technical answer.

Thank you very much for this wonderfull welcome on this community by some *******s around!

Technical answer? It might be dead, might not be. Depends where those pads are used for. If they are just grounds or power delivery there's a chance it works. If they are for data connections to the bus or pci-e or ram slots it might still work but those linked slots won't work.

There is however a 98% chance it's dead.

Cars:
-Crashed: (not my fault ) '94 Nissan 100NX GA16DE (a.k.a. NX1600). Renault Laguna Phase I facelift '99 1.6 K4M. (Broke a strut and smacked a tree).

yeah i agree too, i'll will let it go...another hiding question was: is that safe to test it? but i'll not
also i got strange pcie express lanes problem and before extracting it bios post code say B9 which means: "memory train"
so yes, being optimistic is a thing!

thanks anyway bye

Chill everyone.

In everyone's defense your initial post was very very misleading, we can never know if you are knowledgeable or just an average joe that never opened a PC before.

Yes , even if its not dead its damaged for sure(How damaged?) not even the best can tell you (Unless they have schematics of the exact damaged pins).

And that "Green Skin" is the actual PCB, technically speaking a damaged PCB is not the end of it all but with how tightly everything is in/on a PCB these days its safe to assume anything with a damaged PCB is a goner.

Best solution is to test it.

P.S: Expect most threads to go like this when they lack Info or substance with obvious questions (We had turtle_rig after all), but everyone is friendly and welling to spend hours of their time to help you when needed .

k sorry
also i'm really stupid to underestimate the heat from the back of these vega's at 220W (no backplate WC), the tube just melt...my bad i should stop extract and clean...
trtl_ yé, these 12/24Tx2 goes 30Mh/s VerusHash 150W printed on the soft (pretty much accurate htop + turbostat) 180W..not much!
9.6 10kh/s randomSFX...thats good stuff, stable when you dont burn it like a ******

bye

Hi,
Like dropping fresh meat sometimes, actually way too often just asking questions around here so don't feel like the lone ranger it's the pack not you that's the problem.

Just add some electrical tape over the really badly damaged area so nothing happens there on those contact spots.

It's a helpful community. I think your opening post just didn't have really much detail past a picture. Wasn't sure if something burned or if there was just crap on the CPU needing to be cleaned off. So people extrapolated from what they could see and ran with it.

My thought is that it is probably 99% sure to be dead. If one contact pad was busted that would be one thing as there is a chance its a non-essential pad, but looks like several have been taken out, so you've likely taken out several required pads for the CPU to work. That said, your best bet is to just test it.

Some of them look like either electric-corrosion (at best)
Or fully scraped away pins

Can you elaborate again how that accident exactly happened ?
Was the unit into the socket while fluid run into it ?
Such type of corrosion looks strongly like it was powered on with conductive fluid ~ somehow

It also looks like steel-wool cleaned
And then at the end like somebody scratched it with a screwdriver

Please with easy words, describe how on earth that event happend
I personally can't follow the shorted wording you use
Something vega, something melting, 180W . . . i have no idea what actually happened

At absolute best, these pads marked are just corrosion
The first 3 rows mostly relate to current filtering, or aren't used - well just for grounding
But the rows afterwards nearly all of them except lucky pins are used
The best advice i can give, is taping the first rows on which the PCB is damaged with electrical or capton tape
At least the first two rows ~ so you won't short the PCB
Then clean the rest with isopropyle gently, and or maybe look for non conductive non oily WD-40 "electrical spray"
There are many WD-40's
Y
our socket might also need some cleaning if this appears to look like fluid corrosion
