Blackmagic Forum

Hi there. I have an issue because I want to upgrade from SDR to HDR card by Blackmagic. I google maybe 4 days by now and can't find any proper configuration for my PC. I have AMD Ryzen 9 5900x 12 cores, 32 GB ram, gtx 3080 ti 12 GB, and b450 aorus pro(motherboard), 2 SSDs, 1 m.2 nvme, and 2 HDDs. I want to add a decklink 8 pro card to this configuration but bandwidth on my motherboard will be limited. 8k pro needs PCIe at least 3.0 x8 slots. My GPU needs PCIe 4.0 x16 slots. I know I need a brand-new motherboard but I cant find one which will be ok with my configuration and will be not limited. If someone has the same or near my configuration, I'll be happy to tell me what motherboard use.

Well I just googled Motherboard x16 x8 slot and came up with a supermicro board, as well as a web page "best motherboards with 3x pcie x 16 slots"

Google is your friend.

Or just go to your local computer supply shop and ask a tech what they have.

I should add, always read the motherboard manual, so you understand the domino effect of putting a x16 device in a x16 slot. Quite often it can change how the other slots perform, but i would guess if you need 1 x16, and 1x8, it shouldn't be too hard to find. You may need a new case and processor as well, but thats the fun of upgrading a PC.
