Summary: Buy EVGA, ASUS has too many problems with all their Nvidia chipset boards. SLI Club has alot of input about this! Best now to get the EVGA Nvidia 780i SLI A-1 FTW MoBo, excelent reviews and issue with 45nm is resolved, overclocks well above advertised!
worst Asus motherboard I ever bought, and also the most expensive :-(

Summary: I went thru 4 Asus striker Extreme boards before finding one that would post normally, and that is with ZERO OVERCLOCKING. I don't know what the design flaws of this motherboard are, but there is a lot of 'variety' between boards... You are lucky of you get one that operates to spec.
Summary: The bottom line is that four of 10 ASUS boards could not post long enough to upgrade the bios to 1305 which is essential for a full configuration. Unfortunately the first boards I got for prototyping worked fine. The nightmare followed. Buy something else. Here is my experience.
