I am having an issue when I add a PCI-e card into the 4X PCI-e slot on my lanparty UT sli-d board. The system wont post when the card is in the system, It is an lsi logic megaraid SAS 8308ELP raid card that is a 4X pci-e card, I have tried it in both the 4X slot and the 2nd 16X slot with and without sli enabled, and with both 1 and 2 video cards in the system. I get no video no post with it, and it comes up fine when i dont have the card in the system. I have tried reseating memory and processor and all the pci-e cards, disconnect fans and hard drives, I have a 550w power supply an opteron 170 which was OCed but now isnt, 2GB DDR 500 corsair memory, and i tried with just 1 stick of memory in the system. I also tried switching my proc heatsink and removed and reinstalled my motherboard from the case. LSI claims it is a motherboard issue and not a card issue, so i emailed DFI support, but i wanted to see if anybody here had any ideas.
