My settings:
- All c-state stuff disabled
- EIST/Speedstep disabled
- PLL Overvoltage disabled
- Spread spectrum disabled
- DRAM timings: 9-11-9-28-2N (the rest auto)
- DRAM voltage: 1.635v
- Wattage limits: 250/250/250
- Power saving mod: disabled
- Vcore: 1.375 (fixed)
- LLC: Lvl 3
- PCH Voltage: 1.059v
- PLL Voltage: 1.832v

The key was upping the VTT and VCCSA:
VTT: 1.155v
VCCSA: 1.107v

Increasing those last two was *the* solution to make my 45x+2133 clocks stable. I'll try lowering each voltage a bit at a time to see how low I can go, but 100% stable for now.
...What I'd *really* like is 46 or 47x... How much of a difference would that make in gaming anyway?
Absolutely zip. 100MHz is bugger all. You might want to leave speedstep enabled. I disabled it along with all other power saving options and my CPU really didn't like me doing that. Turned speedstep back on and.. everything is fine again. Very odd.
