coney, can I ask what speed and voltage your memory was running at to start with?
According to Corsair, the SPD on the memory should default it to 1333Mhz at 1.5v, if you want the full 1600Mhz then you have to set it to 1.65v manually.
Are you saying that it initially set it to 1333Mhz at 1.5v yet this was unstable?
You might want to have a look at this thread btw:

Hi,
Your right. The memory is detected as 1333Mhz at 1.5v - at this setting the system boots ok.
If you select the XML profile it is detected as 1600Mhz at 1.65v and the voltage is automatically set at 1.65v - at these settings I encounter the cold boot problem described above.
I have currently left the RAM at 1333Mhz at 1.5v.
My other problem is that I am randomly experiencing what I can only describe as freezing.
I have experienced this with the memory set at 1600 and 1333 and on all versions of BIOS available.
I don't know if this is down to the motherboard or some other component.
I've experienced this freezing in WOW and in Windows. Basically, the screen either freezes or a particular process freezes, hard drive stays on and any sound continues as normal.
Sometimes, if you leave it, it will unfreeze and work as normal. Other times I need to restart the system. It never results in a blue screen.
I think I can rule out the graphics card and PSU as these worked fine in my previous build. I don't think it's the hard drive as WOW and Windows are installed on the SSD. So that only leaves:- Motherboard, Memory, SSD or Processor.
I had a look at the other thread you linked to, interesting stuff from Gibbo. Begs the question why Asus have my memory on the approved list in the manual at 1.65v and why they overclock the BCLK as well!
