Two things for you
The DH57JG does indeed support PM, but you need to run the Intel RST Rapid Store Tech - RAID - then your ports will be PM aware
The MB does not seem to like MICRoN PCI ex cards - the Silicon Image version is fine - but read up on RST and you won't need a PCI ex card
Thanks for your reply... In the mean time I have bought another card a Silion Image SIL3132 and it works properly with PM Support.
As Regards the Intel RST does the motherboard have to be configuratred with AHCI ? Since the software it telling that the system does not meet the minimum requirments...
And if not can it be switched from the BIOS without having to reinstall the OS?
I have a similar issue with Intel SRCSATAWB RAID on DH57JG NAS based.
The system dont boot with 1x 2GB RAM and freezes at post with 58 code indefinitely. With 2x2GB RAM boots ok but RAID startup show "Intel RAID ???" and show wrong device hardware id in Windows 2008 R2 (and Windows 7 x32) device manager.
In others Intel boards desktop boards windows reconized the RAID with PCI\VEN_1000&DEV_0060&SUBSYS_10108086 and DH57JG shows PCI\VEN_1000&DEV_0062&SUBSYS_10108086, install wrong native driver and show "This device cannot start (error code 10)". With the Intel driver the same error.

? Intel SRCSATAWB
Intel support chat said that this board is not designed to raid cards, may work may not.
