E4500 max safe vcore?

Intel's specs say 1.5v. Is this before or after vdroop? Right now I have my E4500 at 3.2ghz. (8x400) But it takes an insane about of juice to get it past 3ghz. Right now I have the vcore at one notch above 1.5v I think its 1.506v. I have been running orthos for the past hour or so far no issues (load temps around 60-62c on both cores. Any lower on the vcore I BSOD'd within a few minutes. What other settings should I be looking at to try and see if I can lower my vcore?

EDIT: heres some caps of my settings in bios

It's best to keep the Vcore below 1.5V. 1.506V won't be too bad, but you might indeed be able to lower it by playing around with your other voltages. Try raising your CPU Termination and MCH Core voltages to 1.3V each, and see if that helps you get stable with less than 1.5V Vcore.

I lowered the vcore to 1 notch below 1.5v and tried raising the CPU Termination and MCH core to 1.3v failed prime in < 20 mins.

Apparently vdroop is a big issue with my board. (GA-EP45-DS3L) with my vcore at 1.51250 CPU-Z shows my idle voltage at 1.472v. Load volts are at 1.456v So after vdroop im under 1.5v. I presume this is safe? I ran prime in blended stress test over night for 8 1/2 hours and it passed. Load temps seem to bounce around a bit according to core temp. I watched it fluctuate from 60-62c on both cores then it would jump up to 65-67c then back down to 60-62c. I checked my log and it did that for the entire stress test. Never went above 67c.

Yep, perfectly safe. As long as the actual voltage is below 1.5V, you're fine.
 
What would be more beneficial? My current OC (8x400) = 3.2ghz @ 1600fsb or (10x333) = 3.33ghz @ 1333fsb? Or would the difference be negligible?
 
Faster clockspeed is faster in general. The speed of the FSB doesn't make much of a difference to performance.
