Why the f*ck not? - a bad ideas only build, by Mussels!

Right... so it wont work as a primary GPU (code 43) but if its the SECONDARY (IGP set as primary) it works fine?

how odd

You're still getting the code 43 error?

When the GPU is installed but i'm booting off the IGP as the primary, i can switch to the 780 and it works fine.

However if the 780 is the primary GPU in any system, its code 43. It's rather strange.

Interesting. That was the original error you were having wasn't it?

at first it would seem working and black screen on 3D, then i got errors loading games, then i got code 43.
I'm trying a BIOS flash, but i get subsystem ID mismatch on all the ones i've found (windforce 780OC) - and the giga utility to flash the BIOSes doesnt load

Damn, I thought reflowing it would help.

The flux probably didn’t make it all the way into middle BGA contacts of the GPU.

I was thinking that after looking at the pictures of it being applied. I looks like there might have been air pocket trapped under the die.

@Mussels
Feel like one more go in the oven? If so, clean the board off completely with 90%+ IPA and then apply the flux, generously, on just two ajoining sides of the GPU die. This will allow the flux to "soak" in under the die as the heat melts it. It's important to keep the board perfectly flat though. What do you have to loose really...

 

[Mussels]

i'll give it another shot when i'm bored, sure

We'll be all looking forwards to the results of such silliness @Mussels

Not silliness. Reflowing does work. It's a service I provide to clients and it works much more often than it doesn't. I've permemanantly revived XB360's, PS3's and the infamous NVidia laptop GPU's. The key is understanding the problem, using the proper tools & supplies, using the right methods and having patience.

 

[Mussels]

the silliness is my total lack of concern for doing the job properly the first time.

Would I be mistaken expecting the same lack of concern on the second and third attempts?

the less i care, the more entertaining it gets.

Exactly!

I wasn't casting aspersions about reflowing in general, just Mussel's efforts with it, as I know reflowing stuff is a great way to fix it if you can.

 

[Mussels]

Okay i have a really bad idea for this, what temp would a GPU need to be for the reflow?

 

[Nuckles56]

It's over 200c I believe so I don't think it's going to work sadly

 

[biffzinker]

Don’t know if this helps:
The temperature of reflow zone will pass melting temperature during this zone with solder paste melted to liquid. During this phase, the temperature of 183℃ above should be maintained for 60 to 90 seconds. Either too short time or too long time possibly causes quality issues of soldering. Thus, it’s extremely essential to control the time span at the temperature of 220±10℃. Normally, the time should be controlled within the range from 10 to 20 seconds.

 

[Mussels]

Oh, i just have a really bad idea i'll try before the rain hits. dont mind me.


This idea is VERY likely to kill the card, should be fun

 

[Nuckles56]

So long as there's an amazing video, we'll be happy

 

[Mussels]

How about a nice GIF? i lacked enough hands

 

[Nuckles56]

That's definitely good enough for me

Is the fire for effect? SO what about the card?

 

[Mussels]

oh no it genuinely caught on fire

i washed it for a bit with some dishes, and now its drying off.
