Real CPU V-core reading (Ya I know, but I have no answer yet)

Ok, the golden question, I know CPU-Z is said to read the actual real-time voltage and I understand the voltage drop theory. But what I want to clear up is I found out the Vdrop on my board GA-P35-DS3L is 0.03V. So for example If I set my BIOS to 1.53V my actual voltage in windows (cpu-z) is 1.5V. Now Is this safe taking the OC guide into mind and to never go over 1.5V for 24/7 use? Or is it not because my BIOS setting is above 1.5V. Also If anyone knows the multi-meter measuring points for a DS3L I'll even measure it out.

It's 1.5v real for 24/7 usage.

The rule of thumb on 65nm is 1.5v air, 1.6v water.

Ok I have it in windows @ 1.504V and when under prime load it drops down to 1.472. Is this safe voltage wise? Right now I was able to run 3dmark06 stable and havent tried long term prime. But what are you opinions? I'm just trying to get a bit more out of it, I thought I was going to get 3.4Ghz easy, but I had a tough time just getting 3.2Ghz. I tried 3.33Ghz 333FSB 2.4x mem 800Mhz And the damn thing woldnt get past vista login with the same voltage applied, yet at 8x400FSB (1600FSB! boards only rated for 1333Mhz it's a DS3L) I was able to at least move around in windows, but with any heavy load would cause it to crash.
