thanks for taking the time , yes I can confirm the steps you quoted ,and yes I have loaded the driver , during install but the drives simply remain invisible , considering what you have said regarding the crucial drives , I have decided to simply leave the "raid) option for the time being , and have gone back to start ,removing all drives and cables , setting the Sata Ports for AHCI, now windows install sees the drives, and installed no problem, the sequential speeds are a little higher than I was getting with the raid (spinners) but the SSD's are way faster dealing with 4k files , this seems to be giving me a considerable speed boost dealing with my large photo files, and just about all aspects of the PC use are a little faster now .
I will look into "other" possibilities later ,when cash flow improves.
been looking for another AMD board , but the gigabyte website seems quite confusing and jumbled lately , not a gamer , though I do need a respectable performer for graphics and high throughput , do you know what are the latest AMD boards out that may fit the bill, there seem to be no dates to say which are the newest board on the website .
and many simply are not available in the uk.
thanks again , graham
