Voltages - I'm confused...

I have a T-Bird 800 and a KT7-RAID motherboard. Of course, I have used a pencil on the CPU, and the multiplier works just fine.

I can go to 900MHz without doing anything to the voltage, but when I go for 950, I have to raise it by 0.075V (from 1.700 to 1.775) to make it stable. I have tried 1GHz at this voltage, but apparently I must go even higher on the voltage to make it stable at 1G. And here's the problem.

I have been told that the T-Bird should be able to handle voltages up to 1.850V, so it looks like I can still go quite a bit higher, right? But: When I set the voltage to 1.700 in the BIOS, the VIA Hardware Monitor (and the PC Health Utility in the BIOS) reports that the voltage is actually 1.76V. And when I raise it to 1.775, the reports say 1.85. So, the question is: can I go any higher? When people tell me it's safe to go up to 1.85V, do they mean the setting in the BIOS or the actual voltage reported by the Hardware Monitor?

If you are properly cooling the TBird it doesn't matter.
The voltage being reported may be incorrect as well. I have my TBird running at 1.88 Volts now as reported ny VIA's hardware monitor. The temp runs about 47C using a F0P32-1 HSF.
When they say it's safe to run it at 1.85 V they are just saying that if the temperature is being controlled it's safe, that includes up to 1.85v or 2.0V for that matter. ( you can't get to 2.0V it's just an example )
