Xfx hd6970

[LiamTheBoss]

So my 6970 is not showing any picture. I have no idea why so i'll go into the story of me mounting my gpu waterblock.

So I started to mount my gpu waterblock, and during this process I ran into some issues, it being a second hand waterblock.

I do not have 1 screw going though the gpu to the block, I also had to use personal screws to attach them together.

After I got it together I put it in my PC case and did the testing of my loop, during testing I discovered the there was a leak in one of my O-rings on the GPU so I started to use a pair or pilers (the non-cutting type) to try and screw it in tighter but that did not work.

I may have put a lot of rotational stress on the gpu while this was happening. But as it was in the PCI-E slot nothing should have happened. Also the card was flooded during this because of the leak, but as my 24pin and GPU connector was no connected at this point it should have been fine. (Bear in mind the 4 pin north bridge power supply was still plugged in.)

So after 2 days of waiting for more coolant and a new fitting to come I drained the system and re-filled it with new coolant.

I have let all the bubbles out and was getting happy (ofc) that my PC was about to work. But then the GPU shows no picture. I dont know why. The POST is fine, 1 beep and there are no issues while its posting the gpu.

I have no-onboard graphics.

Crosshair IV mobo so I have a led style bios.

The GPU is XFX 6970 2GB.

All help will be appreciated!

Alright I took the card out and the block off. There is NO visible damage to the card.

Im starting to wonder if I missed a step during installation.

Is there a blank for the gpu fan connector or something to fool the card into thinking a fan is running?


forgot to mention that I tried an old gpu and it worked. (Old nvidia gpu one of the ones with 4 numbers )

'The card was flooded'? As in the waterblock was filled or card got wet?

If you did flex the card at all it can still break the inner workings of the circuitry. Can you test in another machine? Can you use another PCIE slot for it?

 

[LiamTheBoss]

the area between the waterblock and the back plate was flooded but at that point only the northbridge 4pin was conencted so there shouldnt have been any short circuits

 

[jamesriley94]

Any oxides in the coolant (which should be removed if the water is distilled) will not evaporate and dry off and so will remain on the card, so as soon as it powers back on it can short it out then. Cool is meant to be non-conductive as it uses distilled water, although it is very difficult to fully remove oxide in the water itself.

You need to test more really. I'm not too sure what you want us to say.
If it is water damaged or anything like that - there's nothing you, or any of us could do to fix it.
As I said - Try in a different slot, and try in a different PC if you can.

 

[LiamTheBoss]

So you are saying I should leave it for some more time to dry?

EDIT: Well it got through POST so I assumed it was just an output issue.

 

[jamesriley94]

If the card was completely dead it could still ignore it and make it through POST without recognising it being there.

I'm just saying you need to test it more - if it has been shorted out already, or anything similar - it may not matter however much time you give it - it may just be dead.

Put your old card in, and put the 6970 in a lower slot, with the monitor plugged into the nvidia. Go into the BIOS and see if it's recognised in PCI devices, and device manager

 

[LiamTheBoss]

When I put both in at the same time the computer gave a long non-stop beep (before POST even started or at the very start of it, basically not at the VGA stage). I assumed the cards were conflicting so I just powered down.

 

[jamesriley94]

Alright - try it in a different machine then

 

[LiamTheBoss]

Will do, but the soonest I can is friday at a friends house.

Is there a chance the card can damage a mainboard if its shorted?

 

[jamesriley94]

I think it's possible, but unlikely
