Question on Voltage

[Conscript]

OK, got my system up to 1425mhz (9.5x150), and it running stable with no problems. My question is the about of voltage it's using to do this. I know AMD specs say 1.75->1.85V is within it's specs, and I really would like to keep it with in that. I was over-clocking for a while with the voltage detection enabled, and it always said in the BIOS that the Vcore was 1.85. Is that the true voltage to the CPU (meaning it's at the upper end of MD's recommended amout)? The intersting this is, I decided to manually adjust the voltage on the mobo, and initially just put it at 1.85 with my current settings. Afetr bootup, the bios said Vcore 1.94. Does this mean I'm in a dangerous range for the Athlon? I change the jumpers to 1.825, and the bios says vcore 1.9. I tried 1.8 on the mobo, and it wouldn't get past windows, so currently I'm running teh jumpers at 1.825, but the vcore says 1.9. Is this bad for the CPU? If it means my CPU is going to die, then it's not worth the extra bit I'm getting out of it.Incidently, temps went up a bit, but it's still running at 42C idle and about 47C after a few runs of Sndra's Burn in. What do you guys think?
