Problem description: Just completed a build yesterday and tried booting it up with all RAM installed. Computer responded by cycling power on and off continuously. Googled it and the first response that seemed promising was something up with the RAM.
Attempted fixes: At this point I started trying various fixes from the Googles, which suggested that some boards won't allocate the requisite voltage to RAM and you may have to adjust things manually in the BIOS. Of course, it wasn't POSTing at the time so I didn't have access to the BIOS. I removed all RAM but the one in DIMM 1 and the computer booted up, which was heartening. I adjusted voltage, frequency and manually set timing to match the RAM's specs. Then added more RAM back in and got the same issue. After cycling all the sticks and all the slots, the following picture emerges:
DIMM 1: Boots
DIMM 2: Boots
DIMM 3: Cycling
DIMM 4: Cycling
DIMM 1 & 2: Boots
DIMM 1 & 3: Cycling
DIMM 2 & 4: Cycling
DIMM 1 & 2 & 3& 4: Cycling
Recent changes: None to speak of. This is an initial configuration.
