Do you insulate ALL the VGA?....
Nowadays Rams are cold bugging like crazy you know....
I used to put 3 or 4 layers of insulation tape and guess what did I discovered with the 5870 one!
NO INSULATION at all as for me for all new cards from now on......

I just plastic spraying them a LOT - BUT A LOT - and I just put the LN2 pot on them and that's it.....

When you fully double/triple insulate them, the PCB get's more freezed inside and the rams runs a LOT colder and they cold bugging....

I encoded this problem yesterday during my tests at full LN2 -190*C and at core frequency 13xxMHz when the PCB around the core took that white colour of snow , reached the rams and then the rams started cold bugging....

In such a case I have to put them on the mod I did as for the 5870 to warm them up a bit....

I'll retry it one of these days and I'll see...
