I have Gigabyte x58-ud5 MB with two Gigabyte ATI HD 5450 pcie cards in PCIE1 and PCIE2 slots. My problem is that when I put both of them in and boot the MB, it posts but from only PCIE1 (only monitor attached to monitor 1 comes up). I tried several different combinations: 1. Interchange the PCIE cards (both of them are working good) 2. Change the first display option to PCIE2 in BIOS (when I do this monitor attached to PCIE2 comes up but PCIE1 monitor doesn't come up) I was wondering how to get the display from both the cards at the same time. My config is: Core i7 920 Gigabyte X58-UD5 2XGigabyte ATI HD 5450 3X2GB OCZ OCZ3G1600LV6GK DDR3 1600MHz Thermaltake 850W Arctic Freezer Pro Rev.2 Cooler Antec 900 2 Case P.S. I do not have the MB in the case yet as putting it in the case is causing some kind of short. The MB is currently on a cardboard and another case is on the way!
