If I fire up Prime Small FFTs though the CPU appears to be stable. Anyone know what's going on??

I had to do a hard restart since Vista become unresponsive due to me trying Prime95 Blend and it eating up all my available RAM. I then tried upping the vcore a couple more notches to 1.35v and it wouldn't even POST. The BIOS just recovered and reverted to stock clocks. Then I tried upping the vcore one more time and it got through POST but wouldn't make it into Windows because it said the kernel had been corrupted. So I went back and tried upping my vdimm from 1.6v to 1.66v and that got me to my Vista desktop. I'm at 19x205 and it's running Prime95 Small FFT's no problem but Windows is only detecting 4GB of RAM still. Task Manager does now at least see 4092 total physical memory. Does the problem sound more like my CPU or the motherboard?
please list ALL of your settings.

Multis and voltages.
