well... we are in the same situation buddy.. My wb didnt fit my card and my card is also dead.. sad...

okay... I have now mounted the wb on a different 4870.. but still no contact to the gpu! Am I doing something wrong or is something wrong with the wb??? please respond...

I have been looking around and my memory seems to be standard for the 4870 so i can`t realy see how that should be the problem. The layout on my card is as far as I can see identical to reference design! It must be some problem with the wb..

What is this little hole here? I don`t see it in the picture of the wb on the ac product picture.

qimonda is the name on the memory

Just mounted my new ac waterblock but when i turn on the pc my card is dead.. the D601 led for core voltage fault is on.  I tok of the cooler and noticed that the gpu doesnt get contact with waterblock!  I have a club3d hd4870 and the ac aquagratiX for the hd 4870. Anyone care to help? how ever i try to mount it the gpu doesnt get the right contact with the gpu
