On NCQ - while I see nothing about it in the manual, the mobo recognized my Seagate 200GB SATA drive with NCQ without any issues. I'm at work now but will check tonight to see if there is something listed in device manager that indicates NCQ is enabled and functioning.
On the Orange PCI slot, the manual says, "The orange PCI slot (PCI4) also works as a communcation slot, which allows
you to insert the communcation card." This implies that the slot can be used for comms OR other purposes.
So far, my only issue with this board is that the space between the PCI-Ex16 slot and the first regular PCI slot is very narrow, so if you wanted to insert another PCI card in, you'd need to use PCI 2, 3 or even 4 in order to leave enough space to allow adequate airflow to a cooling-hungry vid card like my BFG 6800GT . I just wouldn't want to cram something right up against it. For now, the system stays nice and cool, but I think that would change if I stuck an Audigy 2ZS card right next the the BFG.
Has anybody else using this mobo got a couple or more PCI slots filled? What's your experience with cooling the vidcard in that situation?
On a positive note, the Zalman 7000 HSF fits just fine, leaving just enough space even for ram with heat spreaders.
