Problem solved, juhuuuuuuuu…
Ok, like this.
If you install windows 7, 64 bit, and Decklink Extreme PCI, you can put only 3,0 (3×1024)GB of RAM and thing will work.
If you put 4 or more not working.
I prove this on my new computer with 8 GB of RAM.
So I have installed dual boot system.
Windows 7, 32 bit, can see 3,5 GB of my 8 GB installed RAM and my decklink work.
Windows 7, 64 bit, can see all 8 GM of RAM, but deckling not working.
So like this I can live, capturing with 32 bit, later working on 64 bit.
If this help somebody please let me know on elvir_radeljas@hotmail.com
