I want to upgrade my computer system so I brought new Motherboard and CPU. My motherboard is Gigabyte GA-Z77X-UD5H and CPU is Intel core I7 2700K. I also brought new 2 4GB DDR3 transcend RAM. I Install all component and system is working fine. After a few days I install a LSI SAS 9211-8i HBA PCIe x8 host adapter card but my system is not recognize it. I got this card from my old system and it is working perfect on that. I also check this card on another gigabyte G45 series motherboard and it is working perfect. I donít understand card is working fine and motherboard is also new so why card is not recognize by motherboard. Anyone has any idea about this problem then please give me the proper solution.
