Can i mantain stability with less vcore?

Hi all, i've been having another go at overclocking my i7 920 D0 recently and have managed to get it up to 3.8Ghz with the following Settings.

Multi: x19
BCLK: 200
Mem Multi: x8
Uncore: x16

Vcore: 1.3375v
QPI/vtt: 1.34v
CPU pll: 1.8v
PCIE: 1.5v
QPI pll: 1.1v
IOH core: 1.1v
ich i/o: 1.5v
ICH core 1.1v

The volts seem pretty high for 3.8 and i'm hitting 83 degrees in prime which is a bit too high really. Any tips on getting it stable with a bit less vcore?

12GB Kingston HyperX 1600
GTX 680 SLI
OCZ ZX 850w PSU

i was able to hit 4ghz on all auto settings.

all you can do is lower cpu v one or two notches and test for stability,all comes down to your cpu

ive had one do 4.2ghz with 1.23v

and a couple others needed 1.35v inc a i7 950

Hi, better of using multi at 21.

i'm still now able to drop the vcore much at 3.8 using 21 multi. Just means i have to under clock my ram

Don't they degrade slightly over time and you require higher vcores to maintain same oc?

No but possible the motherboard providing the voltage can
