It's not that simple though. I have no idea what else you "adjusted" in the bios. The best I can tell you is put them back to auto.
Best thing to do is to undo all changes that don't related to your CPU's overclock, if that makes sense.
VCCIO: starting with the second-gen Sandy Bridge, this voltage is used for feeding all input/output (I/O) pins of the CPU. It is also used to feed the thermal control bus (PECI, Platform Environmental Control Interface). In more recent boards VCCIO is now IO A and IO D.
VCCSA: deals with feeding the integrated PCI Express controller, memory controller, and display engine. VTT was renamed to VCCSA.
So, you can understand why I cannot give you pinpoint details on how to tweak it. It all depends:
-on how close you are to the max ram speed the board can handle,
-what the cpu can actually handle.
-what the ram is capable of
It's all trial and error. But for right now you want things to be stable. Once stable then tweak knowing that 1.1 is a no go.
There is also the possibility that the ram might be faulty. There is no short way of going about figuring it out even if you had other ram sticks. However, it certainly looks like a signaling issue being intermittent like that.
