ATI drivers preventing subzero runs

[mike]

The thing why I am 100% sure that this is only in the driver, is the fact that I have this problem also with a X850XT - I can run subzero without any probs with that XT on an earlier driver.
I had already mayor problems with a X850XT CF editon - with coldbugs running pelted - now things are starting to make more sense.
There might be another issue with the X1800XT - but I will know for sure in a couple of days. I have already a fix for the X850 - but I am not at liberty sharing ATM - not until further testing has been done - hopefully this will fix the X1800 as well.
Again maybe ATI has some concerns with the subzero - or it's just a programming error. Makes no sense at all...

I rather think its bios related

My X1800XT can boot at -30 °C with 5.11 CATs and 5.10, no difference. Core does awesome 855 mhz ^^

In attachment you will find a pic of ATI Tool obviously showing that my BBA ATI x1800XT can boot at minus degrees.

And you have never played with BIOS or anything on your card Eminem? Maybe you got an ES card in a retail box
