Summary: Arrived dead; would not post. Did some web searching and found other people as well who would only get a 0x00 post code and no actual boot. Removed everything to troubleshoot, except CPU, and still wouldn't proceed past the first post code. Had high hopes for this motherboard, as the instructions were very clear (compared to other vendors), but execution was lacking.
Summary: I purchased this board as an upgrade to the earlier version, the DX58SO. I liked the 6 RAM slots, USB 3.0 and other advanced features. I pulled all the peripherals from the older board and would then upgrade to 24 GB of RAM to run VM's and take advantage of the 6gb SATA interface. On boot up got the 3 one second beeps continuously.
