weird trace on the PCI bracket of my GPU

[xt_hydra]

hi.. i recently had some problem with my ancient motherboard configuration

(wich i think i booted too much because after a while it refused to complete the boot process(but now its fine))

and so i took out my GPU to take a quick look at the bracket to see some colors difference.. like somekind of burnt traces

if someone is wondering if i had some power outage.. it happened 2-3 this year..i didnt really care much.. so.. lol

*/EDIT*/

oh and i use HDMI... cuz i have a TV

*/EDIT*/

do someone know what might have caused that?

*/EDIT//2*/

guys i think i might have a serious problem.. i switched from an MSI 990 FXA-GD80 to a 970A-GD45

and i noticed a serious lag issue when i killed diablo at inferno (diablo 3)

then i opened "open hardware monitor"

to see the worst glitch of my life!

i think my FSB almost exploded or something because of an electrical discharge

but as we can see only my CPU got the discharge to 70 celcius

it lasted 3 second

that looks brutal. I would loved to have seen if the bracket was glowing red ;P :D

are you kidding?

because i'm not even sure if thats a reaction overtime

i'm seriously wondering what happened.. i mean.. my XFX 6870 is still working just fine

Yes, I was kidding.

dude that card looks like you spilled some motor oil over it, or someone touched it with oily hands, because oils leave this kind of residue on stuff, it looks like rainbow.

try taking your card out and clean it with a dry cloth, try smelling it and see...

[ZeroPlasm]

I think it is a problem with your power supply, somehow it is delivering "Dirty power" to your rig. Try borrowing a power supply and try it out with yoir rig. If the problem still persist, try using a UPS.

Those are heat stains, typically caused by.. well, heat. Usually it needs to get pretty hot in order to look like that (have a look at motorbike exhausts) but that hasn't happened, otherwise your monitor cables would've molten as well.

Also I don't understand your original post.. What glitch are you talking about? And what lasted 3 seconds?

Why isn't this guy getting the OC record? 3 second 16 Ghz overclock :DDD

[Umeshwarnath]

Ladies and gentleman we have a new world record........ It is a staggering 16.15 ghz overclock........!!! Jk. Something is seriously wtong?

Run a burn test like fur-mark or do a constant loop of unigine heaven and monitor the gpu temps. If you have an infared thermometer just check the key points in your system to see how the temps match to the software values. Also, get a multimeter and check the voltage going to all the points in your system under load because if you have "dirty power" getting thrown around by the PSU you'll see varying voltages by at least 10% from the norm. My money is that there have been short circuits in your system from the outages and the GPU has been damaged. As for the "burn marks" on the bracket, I would suspect a short-circuit.

Damn, world record OC right here!

Did you happen to touch your thermal grease and then touch the GPU? Because that's an oil stain.

If heat cause that something would have melted in the vicinity.

What PSU are you using?

[Salmiakbal]

There's no way that's an oil stain. Oil only gives a rainbow effect when combined with water (washing away motor oil with a hose) and thermal grease isn't even an oily substance.

Usually heat stains like that form when something is subjected to a large amount of heat (motorcycle exhausts) however they can also form when subjected to relatively small amounts of heat for long periods of time (like when gaming in this case)

So why specifically this graphics card might you ask? Well, if the stainless steel used by this card has low-chromium content and rough surface finish then it's more prone to discoloration, so that's probably what has happened.

My money is that there have been short circuits in your system from the outages and the GPU has been damaged.

That's complete nonsense though, why would there be short circuits due to power outages?

Well' date=' if the stainless steel used by this card has low-chromium content and rough surface finish then it's more prone to discoloration, so that's probably what has happened.[/quote']

if i compare the bracket from 6000 series to 7000

the 7000 is black.. so it might be a know problem with some cables... maybe but.. my

6870 doesnt have a rough texture.. its just look slithly less shiny.. so is that what you meant by low-chromium?

ill try to put oil on my wireless bracket.. it look slightly more shiny

well anyway i updated my BIOS(6 months old).. it might have been a bug between the OS and the BIOS

PSU :: XION 1000 watt

1000P14F

2X12 VOLT (20 AMP) && 4X12 VOLT (30 AMP) = 900 watt

UPS? well that would be useful.. i live in an appartement with quite some computers

i remember running the stock BIOS version of my board without support for NB-PCI frequency and it was overheating my GPU in diablo 3
