After a big disappointment with 2 ASUS U3S6 I had chosen because PCIe 4x and 1x non, these 2 cards then were perfectly recognized by my HP ProLiant ML150 G6, and Windows Server 2008 R2 x64. Where ASUS, well recognized by the BIOS, caused a blue screen when Windows starts and collapsing my power.
In short, I highly recommend this purchase.
Note: excellent technical exchange mail with Kalea, as the cards arrive in unmarked boxes where it is indicated as SATA II. But those are SATA III Chipset with ASM1061.
