Hello. I made a post on reddit r/overclocking but it didn't get much attention.

My motherboard: ASUS Rampage II Extreme

RAM: Triple Channel 12 GB (6 sticks)
1 Kit (3 sticks) of this: https://www.google.ca/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=cm3x2g1333c9

CPU Cooler: Cooler Master V8

Currently I have the following overclock:

BCLK: 200
Multiplier: 22
Effective Clock speed: 4400
RAM: 1600
UCLK: Around 3000 (This is the Uncore. It is basically RAM x 1.875... Supposed to use 1.5 - 2 times RAM for Westmere Xeons but I like 1.875)

Vcore: 1.38ish (If I remember right. Was set to 1.38something in bios)
PLL: 1.81v
QPI: 1.25v
DRAM: 1.65v (rating for my memory sticks)

RAM Timings: 9-9-9-24 entered manually. Rest are AUTO.
Load-Line Calibration: Enabled (This is causing vcore to go up under load. It spiked to a max of 1.396V when running Intel Burn Test as reported by HWMoniter.)
Power saving stuff like C1E, Speedstep, Speed State: Disabled.
Hyper-Threading: Disabled

Max temp on the 6 cores when running Intel Burn Test is 66C to 76C.

Some questions.

1) Difference between C1E, Speed Step, C States ? I wouldn't mind a lower power bill so can I enable any of these to work with my overclock ?

2) Leave hyperthreading disabled ? (only use the system for gaming, no video edition or anything)

3) My BIGGEST CONCERN: Load Line Calibration is causing the CPU Voltage to go up under load. HWMonitor is showing 1.39v - 1.42v with a max spike of 1.435v even though I have vcore set in BIOS to 1.38125 or something. Is that vcore too high under load ? I could disable LLC but then it won't be stable.

PS: The system was stable at 4.2 with vcore set to Intel's reccomended max of 1.35. Had to bump it to 1.38something to get it stable for 4.4.

Actually, it might have been stable under 1.35 for 4.2. I was too lazy to test that so I did a quick and dirty 1.35 because my goal was 4.4 to begin with.
