Hello everyone,
I'm looking for feedback on "fine-tuning" an overclock and possible increase. My system as follows:

cpu: i7 920 D0
mobo: EVGA E758-A1
memory: OCZ Platinum 6GB (1600)
psu: corsair 850hx
gpu: xfx hd 5870
cooler: Prolimatech Megahalems

Last stable OC as of 1/5/12 @ 3.66

Frequency Control;
CPU Multiplier ( 20X )
CPU Host Frequency (Mhz) ( 183 ) [3850Mhz (183x21)]
MCH Strap ( Auto )
CPU Uncore Frequency (Mhz) [2933 (16X )]
CPU Clock Skew ( 0 ps )
Spread Spectrum ( Disabled )
PCIE Frequency (Mhz) ( 100 )

Voltage Control;
EVGA VDroop Control ( With VDroop )
CPU VCore ( 1.34375v )
CPU VTT Voltage ( +150 )
CPU PLL VCore ( Auto )
DIMM Voltage ( 1.650 )
QPI PLL VCore ( Auto )
IOH VCore ( 1.4 )
PWM Frequency ( 800KHz )

CPU Feature;

At 3.4 my temps were around 60 during 14hrs of Prime. At my current pace of 3.6 my temps maxed at 68 after 12 hours of Prime; however, the room was rather muggy and I was too lazy to put the ceiling fan, stand-alone fan, or AC on lol. Prior to discontinuing Prime I added some air circulation and temps reduced to 65 (was still fairly muggy). I have yet to see any errors or BSODs. Are there any settings I should adjust for better performance? What adjustments could I make to hit 3.8-4.0 without overstressing the cpu and temps?

Thank you for assistance!
