I have only a PCIe 2.0 x4 and a PCIe 3.0 x16 free and I need to install a 10Gbps SFP+ card and a graphic card for transcoding with Jellyfin (the CPU is an old E5-2620 v2). Since I can’t find any SFP+ card that is x4, do you know a graphic card with decent transcoding capabilities (I’d day 2 4K simultaneously) that is only PCIe 2.0 x4?
Edit: the x4 slot is full length.
Re-reading your post, I just realized you’re probably trying to put a video card in the second PCI-E slot and you need to make sure your board will support that. Some boards will not boot if the only video device is not in the primary slot. If you have onboard video from the CPU this won’t be an issue. But definitely double check the manual for your motherboard.
Yes, I would install the video cars in the second PCI slot, but the motherboard has an integrated video card, does that count? By the way, I don’t have alternatives, if it will not boot, I will not use the graphic card. Thanks!
