ATI Tool 0.26 + X1900XTX = Black screen??

[arnic]

HI, I am new to this forum. When I try to use the Find Max core button in ATI tool, it reach around 73x+ and then my screen will turn black and all i can do is restart the computer. I can use the find max memory with no problem, just not the find max core. Also, I have new to ATI card, I used nvidia card for all my life and decided to change to ATI. Is this a bug or just my card?

Also, I can move the slider with 3d screen to 722. For cooling I have watercooled the card and reach around 43 on load.

Any help will be good, thank!

You shouldn't rely on the Find Max core/ memory function.
Do it manually and scan for artifacts for at lease 30 mins without error.
