opengl pci express
I'm getting conflicting opinions on this one. I need to build a 4
monitor capable machine from a EP45-UD3P Gigabyte board. It also has to run OpenGL cards. This board has only 1 PCIEx16 and 1 PCIEx8 slots. Will it work and multi-monitor with identical cards in each slot? |

This board has only 1 PCIEx16 and 1 PCIEx8 slots. Will it work and multi-monitor with identical cards in each slot? The P45 has x16 lanes on the Northbridge. These can be split, to make two x8 interfaces. If you look at a number of P45 boards, which have two video card slots, there are four small chips next to the primary slot. Those chips are used for "lane steering". When two video cards are present, the slots run x8/x8. When a single video card is used (in the primary slot), all x16 lanes are connected to the primary slot. The four little chips take the place of the "paddle card" which was present on previous generations of motherboards. So to answer your question, when you use two slots, chances are they'll each be getting x8 bandwidth. (Since I don't know the part number of the four small chips used, I don't know if both PCI Express version 2 and version 1 modes are supported. I presume they are.) As for OpenGL capabilities, check the advert for your prospective card. For example, on this card... http://ati.amd.com/products/fireglv8650/index.html "... has added even more innovation with features like native multi-card support, so users can see more and do more with four displays and AutoDetect" Check your advertising, to see if there is some notion of multi-card support. While I couldn't find a statement on the Nvidia site, this article mentions four display support with a pair of Quadro FX5600. http://machinedesign.com/article/sof...s-display-0424 If there wasn't multicard support, there is still a way of doing it. You can use one video card with two display connectors, then connect two Matrox DualHead2Go adapters, to drive four monitors. The pairs of monitors have a fixed relation to one another then (as a 2560x1024 output on one of the video card connectors, is split mechanically into two 1280x1024 displays for a pair of monitors). Some cards support wider display modes than others, and the resolution of each display fed by the DualHead2Go, will be limited by the video card's capability. The Matrox product page has some tables for various cards, showing what resolution limits exist. HTH, Paul |

I'm thinking the PCIE standard would/ should be backward compatible. |
