Summary: I had good luck with Intel boards in the past. I guess that it was luck. This board was nothing but trouble. After several frustrating days of dealing with it (I could never get it to boot) and the Intel "help" chat line, I returned it. It was apparently DOA and there was nothing that could be done to revive it. Had I realized how many people have had problems with this board and the many different types of problems, I would not have ordered it.
Summary: I have been purchased the first DX58SO MOBO on february 20 with the i7-920, then few weeks I received them at my place (I live in Venezuela). Firts all work nice and well at firts boot. The Windows XP SP2 was installed without problems (in 18min). Only have 3GB detected from 4GB installed, but not problem at all. All drivers was installed without problems. The BIOS was updated as well.
Summary: The Intel DX58SO Core i7 Extreme Edition ATX board's design could use some improvement. The S-ata plugs are located behind the hard drives making you use the 90 degree S-ata connector (which are supplied) but very hard to get to. The snap on cpu cooler that comes stock with the i7 processor snaps in OK, but, they are just holes in the MotherBoard, no snap in hardware seats. This allows the cooler to vibrate making an audible sound when it runs.
