AMD south bridge SB950 ( in Gigabyte 970A-DS3P rev 2.1 ) has 2 flaws

[pbx...@gmail.com]

i) Out of 6 SATA sockets, only 2 ( 4th & 6th ) can pass Microsoft's check during
installation of Windows 7/ 8/ 8.1/ 10.
ii) If 2 ssd are connected, both ssd's OS ( & boot sector ) installed will be
ruined in just 24 hr's use ; just 1 ssd can be controlled ( via 4th / 6th
socket ) without error.

These 4 sockets can pass, only if 1 ssd is connected, north bridge ( 970 ) & HT Link speeds are both 1.8 ghz, voltage auto, north & south bridges & gpu are well cooled ( 2ndary / tertiary hsinks & fans added ). Weird.
I want to post a photo of Microsoft's rejection, but this site does not allow.
