Vcore at 1.88volts?!

[David]

I have a Jetway 663AS Pro Mobo with teh KT133A Chipset. I choose -0.5 volts in the BIOS (A10) and it boots up at...1.88Volts.
Is this REALLY at 1.88volts or is the detector wrong? could I safely use this to overclock?

that doesnt seem like a common voltage-maybe its closer to 1.85v but you coud go as high as your mobo will let you, as long as you have good cooling

The strange thing is, I get 1.88 when I choose to REDUCE the voltage by 0.05volts from 1.55

Eh?! What the heck - is the BIOS lying or am I really running at 1.88volts

Is it safe?
