Seems like I misjudged the difficulty I would encounter installing the Asus Striker Extreme motherboard.
Before making this purchase I had carried out a quick search of the Asus support forum and come to the conclusion that at the very least the Striker Extreme board that I'd chosen for the quad-core project was going to turn out to be a pain to set up. At the very least I was expecting to have to jig about with the RAM voltage to get the system to boot up past POST reliably. I also expected to have to install the latest BIOS update. The truth is that I've got one system done and it's getting past POST just fine. There may be problems later on, but I'm prepared for these. So far the Asus Striker Extreme strikes me as a darn nice board.
The fine weather means that I'm behind on the build (well, I didn't really have a schedule but I did kinda expect to have it finished by today) but I'll get them finished tomorrow.
I'll try to get some photos posted tomorrow ... I'm particularly interested in showing you what a tight squeeze it was getting the Arctic Cooling Freezer 7 Pro past the heat pipes on the board!
