Have a new Gigabyte Z97X-UD5H motherboard and Intel SSDSC2BF480H501 2500 series enterprise-level drives (OEM versions from NewEgg), and the BIOS won't see the Intel drives. I've upgraded the mobo BIOS to 10F (the latest), updated the Intel drives to the latest firmeware with the Intel Toolbox utility, rebooted, loaded the "optimized defaults", but no joy. I've swapped power cables, SATA cables, etc etc - still nothing. I have only my keyboard, mouse, DVD drive, USB hub, a single 8gb memory stick (the correct kind according to the Gigabyte site list) and a single monitor (installed on the onboard video currently). I have the network cable connected. No other peripherals are installed.
The PSU is a new 550w ThermalTake from BB, and the voltage is correct, and will power my older platter drives perfectly well. The board also report correct power in the BIOS screens.
If I put the Intel drives in another machine with an older ASUS mobo, they're recognized. As mentioned, while they were in that machine I ran the Intel Toobox and updated the drive to the latest firmware. The ASUS systems shows the discs in disk management, allows me to format them, etc etc.
Is there something obvious I'm missing? Or do I have a bad mobo, or incompatible components?
