I've been playing with 2600K for a few days now.It seems that my 2600K's sweet spot is around 47 * 100 = 4.7GHz. It's LinX 50 loops stable but would fail Prime95 in 20 minutes (BSOD 124).

I wonder what VccSA and VccIO actually do and its importance. Which one powers the IMC? Some says it's VccSA while others say VccIO.

Here's my rig setup and some configuration I've made.

Core i7 2600K [L041B]
Asus P8P67 Pro Bios 1003
G.Skill 16000CL6D-4GBPIS @1866 6-9-6-24 1T
EVGA GTX580

Multiplier: 47 (bench-able @5.0GHz vcore 1.42)
BClk: 100
Vcore: 1.355 - 1.360
Load Line Calibration: Ultra High (Lower than this cause instability/huge Vdroop under load, Extreme= exceed the voltage set in BIOS under load)
CPU Capability: 120% - 130%
VccIO: Auto
VccSA: 0.975
Vdimm: 1.65v
PLL: Auto
Phase Control: Optimized
