SSD Plus wird bei Fastboot nicht erkannt

I have a newly bought SDD PLUS 480 and it is not recognized when using Fast boot. I have Gigabyte Mainboard, I prefer still old fashioned BIOS (not shure if else everthing would work fine). My issue is that with nice fast boot the ssd is not recocnized by the BIOS, but my much older OCZ is. I thougt maybe it is firmware issue, I have UG400RL, but the SSD Toolkit doesn’t offer any firmware update. What else I could do, or could be a manufacturing issue?
Thansk a lot for any help
