Re: 520 SDD incompatible with LSI2308 on SuperMicro X9DA7, W2012

I have toolbox 3.1.2 running with Windows Server 2012 with Intel Series 520 240GB drives on a Gigabyte GA-Z77X-UP4TH.  It works fine.

 

I also have toolbox 3.1.2 running on Windows 7 Pro with Intel Series 520 240GB drives on a SuperMicro X9DA7 connected to both the C602 and the LSI2308.  Driver updates alone will help with Series 520 240GB drives connected to the C602, but not the LSI2308.  The only way I got Series 520 240GB drives on a SuperMicro X9DA7 connected to the LSI2308 to work was to do all of the following:

 

1/  Update Drivers as you did

2/  Change LSI firmware to IT mode as you tried, and

3/  Update the SuperMicro system BIO to AMI BIOS X9DA73.226, this updates the Intel SCU to v 3.5.x

 

With these changes toolbox will work with all Series 520 240GB drives on either controller on a SuperMicro X9DA7, however, there is still an issue:

 

The Series 520 drive does not contain a capacitor backup like the series 320 or 710.  Per Intel SCU documentation, when using Intel SCU versions prior to v3.6 this type of SSD can "go to sleep" at inopportune times causing data loss.  Intel released v 3.6.x of the SCU in November, 2012 to fix this problem.  Unfortunately, SuperMicro, as of May, 2013, has yet to release an update to the system BIOS for the X9DA7 with SCU v 3.6.  After 9 months of struggling with this issue on an X9DA7, I have concluded that this motherboard is junk and SuperMicro support lacking.
