Windows 7 64 bit + 7.6 Decklink drivers = not working
Just a heads up for anyone. Just moved from windows 7 32 bit to 64 bit. Installed latest Decklink 7.6 drivers and my Decklink SDI will not work. Hopefully this is fixed asap. But in the meantime if you have a Decklink SDI that’s working on 32 bit then don’t move just yet.

Hi Brett,
Can you elaborate on what exactly is now working?

It works fine on 32 bit which is what I’ve been using and does not work under 64 bit. Only moved to 64 bit in preparation for CS5. So at the moment this is a big problem as Premiere Pro and After effects are native 64 bit.

Hi Brett,
Firstly, does the card show up when you go into the Blackmagic control panel in Windows 7 64-bit?

After doing some playing I found it will work as long as you don’t use above 3.5GB ram. This is on a 4GB ram setup. Under 3.5GB it will work okay above and it will not respond. This is on PCI Decklink SDI.

Hello Brett
I have the same situation with my Decklink Extreme PCI-X card, can you explain in more details your computer configuration because I installed 4G ram and the card not working with Vista 64, did Windows 7 64 working ?
and how you reduce the memory from 4G to 3.5G ram in windows 7 ?regards

Ah, we had this problem with Decklink cards back in 2007, when we built machines running XP64 with 8GB RAM.
The problem, according to Blackmagic, was that the PCI cards were unable to work in machines with larger amounts of RAM, as you have described.
We had to remove and sell our PCI cards and replace with PCIe which have been fixed from a hardware point-of-view to be compatible.
So, if your cards are PCI, there is your problem and it will never be fixable as it is a hardware issue. Replace with PCIe units and you should be fine.

Hello Dominic
when we talk about 3 Boxx workstation do not contain PCI-E slot then it’s a big problem and I think that it’s not my problem but decklink support problem
any way I solved the problem and all Boxx’s now working great with windows 64 bit with 4G ram

Hi Brett
it seems we may be experiencing the same problem with the PCI card. Can you tell me how you limited memory to 3.5Gb? I also have some driver/profile installation issues:

Is that something you have any experience with?
thanks for any help you can give!
