SM951 as OS boot device information

Is the 1.30B BIOS update for Z97 Exteme 6/3.1? Couldn't find it in the update section would you post a link?

You can contact ASRock support in the link below. If you clicked on the orange colored font Support link at the top of every forum page, all the ASRock support links are listed, including this one:

On a Z97 board, PCIe booting through an Ultra M.2 port is one thing, and through a PCIe slot is another. Using a PCIe slot may require a UEFI/BIOS update.

Thx parsec.  I sent a note to support asking if the pro4 could boot the 950 from a PCIe slot.  I'll let you know what they say.  

If anyone wants to monitor the temperatures of their AHCI SM951s in a RAID 0 array (or not), try CrystalDiskInfo. By some miracle it can read the temperature data of these SSDs while a member of a RAID 0 array, which is a great accomplishment IMO.



You can also choose a graph Option by choosing the temperature SMART attribute.

Thanks for posting your experience Ronzer, although I'm not happy you lost your RAID 0 array.

Your description of the failure is identical to mine. I never had this happen with SATA SSD RAID 0 arrays. I could clear the UEFI or update to a new version, but all I had to do is reset the SATA mode to RAID right after the clear or update, and the RAID 0 array was fine.

I have no idea how to avoid this problem yet... or if it is even possible. I'm blaming it on the RST PCIe Remapping option, but that is really just a guess. I don't see this as a problem with the board or the UEFI in general. It might be due to the 14.5 Option ROM, but that is a pure guess.

IF the default setting of RST PCIe Remapping was Enabled, then things might be different, but doing that would require SATA SSD users to Disable that option.

Macrium Reflect has worked great for me with SATA RAID 0 arrays, with the UEFI configured as needed for PCIe SSDs. I have not yet attempted to restore the OS from a Macrium backup and recovery media USB flash drive which is required for that process.

The only other technique I have not tried is removing the SM951s before the UEFI clear or update, then resetting RST PCIe Remapping to Enabled, and mounting the SM951s again. A bit of a pain to do, if it will even work.

This is a cutting edge thing we are doing, the first board and Intel IRST driver that allows these RAID 0 arrays, plus a new chipset. I can't imagine this situation being permanently the way it is... or at least I hope so...
