Hi,all
Heres BMD solution:
Please have a look at, too: https://www.blackmagic-design.com/support/detail.asp?techID=160
The short version is that customers should not use more than 3 GB of
RAM with 64-bit versions of Windows and that most customers should
continue using 32-bit versions of Windows. The DeckLink and Multibridge
Minimum System Requirements support pages have also been updated to
advise a maximum of 3 GB of RAM.
Having said that, we would urge most customers to continue using 32-bit
versions of Windows as the 64-bit versions are really only of use to
some developers. Applications such as Premiere Pro and After Effects
are 32-bit applications and will run more slowly on a 64-bit version of
Windows and there are absolutely no benefits to doing this.
We regard the use of 64-bit versions of Windows, with commercial video
software and Blackmagic hardware, as something to avoid as there are no
benefits and in fact there is likely to be performance degradation. The
only early adopters who should need to use 64-bit versions of Windows
will be some developers.
The reason for releasing 64-bit Windows versions of our drivers was to
make some developers happy. However we are hearing from customers who
have mistakenly assumed that there is something “better” about the
64-bit versions of Windows and are now running in to problems with lack
of support, for mainstream video applications, and also instability
with more than 3 GB of RAM.

We tried it with 3GB and now it works perfectly – and I think BMD will work on it. Because there are a lot of compositors outside who needs more than 3GB.
Cheers,
Oliver
