I found this thread that seemed to have the solution:
http://forums.ocworkbench.com/showthread.php?t=153800
I'm using low-profile memory to fit under the Noctua NH-U14S CPU cooler I'm using and that thread indicates the board may not recognize low-voltage DIMMs. I put in one DIMM of regular voltage memory and tried to boot so I could go into the BIOS and set the voltage manually.
The same thing happens -- power comes on for about one second and then goes off.
I can only put the regular-size DIMM into the B2 slot. It won't fit under the CPU cooler (which is why I got low-profile memory). The manual doesn't indicate if it's going to work with the memory in that slot but I wouldn't expect it to. But getting it into the A1 or B1 slot means removing the CPU cooler, after which I'll need to clean the CPU, reapply paste and reattach it.
So before I do that I'd like to have some idea if I've identified the problem and if removing the cooler and installing the regular DIMM in another slot will be necessary.
I haven't had any replies to this thread so far but I see there are a lot of very knowledgeable people here (far more knowledgeable than me).
Can anyone here help?
Thanks.
Mike
