| Epox Tech - I really appreciated your and Aedan's explanation of the Vcore variation but there are a number of reports in other forums of this voltage variation causing boot failure by reducing the Vcore to too low a value during bootup. You will remember that in Aedan's explanation he stated that the lowest Vcore was 1.45
A 1.55v VCORE isn't over volting! In fact AMD's specifications state that the VCO requires an increase in voltage to 1.55v in order to remain stable through some ACPI state transitions. The processor itself changes the VID pins to enable this increase in voltage. During P state transitions, a stock processor will go through VCORE voltages of 1.45V, 1.475V, 1.5V, 1.525V and 1.55V. When the processor is idle, the processor's P state will leave the VID pins set to 1.45V.
This is one of the comments
OMG, nevermind, I was just over reacting. It doesn't fix my Vcore fluctuation issue. The next reboot, I had a cold boot which I had to reset my jumper again after flashing to the lastest BIOS. At the end, my system won't boot if i leave it default at 1.55v which then drops down to 1.35-1.40v during bootup. I had to raise my vcore setting to at least 1.6-1.65v to avoid system instability. The Problem still exists...
There are are also other comments implying that Epox are aware of the problem and are working on it.
Would you like to comment further on this.
