I'm trying to solve a problem with mine. I've installed the block three times now.

First off I did get the paper washers and also instructions I believe to not over tighten.

The score is that I'm getting lockups. On the second time of removing the block, I was intending to take the card back. I stuck the stock air cooling back on, and put the card back in the machine just to check some stuff and the lockups had gone.

There's so many parameters that I don't know if it's drivers or not. Anyway have stuck the block back on and I'm getting lockups again. Can't make it through 3dmark06 at 750/900. The key thing is that I am hearing that high pitch sound. More intense when 1.25v are going through the card.

I wonder if that's due to the screws being over tightened? I'm going to try and loosen them up a bit. Fun'n'games.
