As a point of 'history' for this PC, I had some serious problems with the original motherboard as discussed in this thread.
I finally got my RMA motherboard back from MSI so I have my new Barton 2600+ burning in at 2013 Mhz (11.5x175) for now everything seems to be stable. I may end up pushing it higher later on, but I'd like to resolve a strange voltage issue first if possible.
My question is regarding the vCore voltage for the CPU. AMD lists the default core voltage for this processor (it's a mobile version) as 1.5 volts. However, when I select "CPU default" for voltage in the BIOS, the system boots at 1.45 volts. This isn't a problem in itself since the system appears to be stable - and cooler - at that setting although overclocking is limited, but if I intentionally crash the PC (hold down the power button, etc.) the system restarts with the vCore set at 1.82 volts. This is obviously way too high, and when it happens the CPU temperature spikes as high as 80C or more. I manually set the vCore to 1.55 volts as this is the lowest manual setting in the motherboard's BIOS and the system seems to run stable but it is running warmer than I would like because of the extra power being pushed through the CPU. Is there any way to manually force the MSI K7N2 Delta2-LSR to run at 1.5 volts other than through the Core Center software within Windows? If I have to use the MSI Core Center utility, I'll do that, particularly since it is easier to do overclocking there than in the BIOS, but I'd really prefer to not have the system even booting up at 1.55 vCore for now. I may end up leaving it that way permanently if I can get my CPU temperature down enough that I push the overclock higher than it is now, so this isn't a critical issue, but it is somewhat annoying.
I have already updated to the newest BIOS for this motherboard since I had to do that to get the system to recognize the Barton properly.
My PSU is a TTGI 450 Watt. It's not top of the line, but is a solid PSU and the voltages on all rails are well within specs when idle and under load as long as the BIOS doesn't set the wrong voltage level. The main problem is the problem with incorrect voltage settings when "CPU default" is selected for vCore in the BIOS.
