PCIe x1 - DeckLink quad (16 lanes?) I'm not very familiar with CPU/MB lanes and want to know if I have no problems with motherboard like this: 40-Lane CPU- 3 x PCIe 3.0/2.0 x16 (x16, x16/x16, x16/x16/x8) *1 28-Lane CPU- 3 x PCIe 3.0/2.0 x16 ( x16, x16/x8, x16/x8/x4) *2 1 x PCIe 2.0 x16 (x4 mode) *3 2 x PCIe 2.0 x1 (x1 mode) *3 1* The PCIe x16_4 shares bandwidth with M.2 x4. When M.2 socket is occupied, the PCIe x16_4 slot will be disabled.
2* The PCIe x16_4 shares bandwidth with M.2 x4. When M.2 socket is occupied, the PCIe x16_4 slot will be disabled.The PCIe x16_3 slot support x8 devices only.
3* The PCIe x16_2, PCIe x1_1 and USB3_E56 connectors share the same bandwidth. By default, the PCIe x16_2 slot and PCIe x1_1 slot will automatically run at x1 mode with USB3_E56 enabled for best resource optimization.Or this one? Blackmagic cards use 1 lane for a single 1080 stream. so a decklink mini recorder or an intensity pro, use a single lane. A 4K card uses 4 lanes, so does a quad 1080 card. You can easily check for this by using the desktop utility of Blackmagic, and creating a status report in the 'about' tab. If you have 6 slots, and on each a 4 lane card, you get 24 lanes, add your graphic card with 16 lanes and you will have 40 lanes used. This could give you 24 HD inputs. That's theory, because most motherboards will cut corners somewhere and your system uses some pcie lanes for other things as well. Watch out for PLX chips too, they're made to route the traffic but can do terrible things with live video. I once posted here somewhere a breakdown of a system that is sold by livestream.com. you can find the hardware they used over there. Except for the weak video card, you could use the same motherboard and be safe. We now own a second system with a 40 lanes xeon, but the quad cards lock up for some mysterious reason, that's why we didn't finish it yet. It must have to do something with the motherboard, but after checking multiple times, we never found the reason. until we can find the reason, we won't finish it. stupid, since we spent a lot of money on the hardware. In theory the motherboard should handle it, but in practise it locks up with quad YUAN cards. Strange, because our 16 lanes system handles them just fine. I'm just saying this, because computers can sometimes do crazy things that are not explainable with just theory :) It's safe to say you should never push a system to its limits lanes whise. Your setup should be fine in theory, any modern board will take these 6 HD inputs. We ran tests on an i7 2600k (16 lanes) and it could handle 5 HD inputs and run stable, 6 made it a little unstable, although it was sending the video, if we started recording and streaming the system would hang a little. We had good results with ASUS and MSI motherboards, an Asusrock one is failing on us right now though. No idea if it's the brand, the design, ..
