Hello everyone, I have had issues with my upgraded rebuild for sometime. Long story short if you have a SATA host controller with a AS Media Chip and the card is not seen by your MB. It is not the MB it is the card. You have to flash an older BIOS onto the card to get it to work correctly and the card must be updated in a non 600 series MB. This is the link that has the Bios firmware and the PDF that will explain how to upgrade the BIOS on the card. https://www.silverstonetek.com/en/product/info
