Lower CPU speed to about 3.8Ghz (preferably using lower bClk and high CPU multi) and then try to increase dram speed.
If you still get no POST/unstable, try to divide if it is RAM or Uncore by running the Uncore at the same speed but DRAM at lower speed.
Keep in mind that on some cpus, higher Uncore speeds require increase in DRAM voltage.

BTW, what M/B are you using ?
Read my post again
I already ruled out Uncore, because I can run 20x uncore mult fine no problems.
Specs see sig, it's a DFI x58.
