(Sig. for specs)

Whatever I set the vcore to in bios above 1.45, it doesn't seem to change. It reads 1.45 in cpuz, and 1.50-1.52 in SpeedFan. I got a pretty good stable overclock, but I think if I could up the voltage another 0.05V, I could get more MHz. Any way to do that with this board?

I have the BIOS Vcore set over 1.5V here, but it ain't showing: http://www.intpcentral.com/uploads/2690.JPG

I have noticed the A8N32 being very strange when it comes to v-core. I set my vcore from 1.30-1.40 and it always shows 1.39 in every checking program(CPUZ, Speedfan, Asus PC probe II and AI Booster). I think the motherboard automatically looks for an optimal v-core and ignores your voltage settings if it feels they arent good. Maybe it is some form of internal circuit protection, or just a bad design.

Currently my Opteron 170 is running at 2.667 using "stock vcore", as in its set to 1.350 in the bios. But CPUZ and everything read 1.39, so that could account for my quite nice "stock vcore" overclock.

I dont know if there is any workaround as of yet, but it is frustrating not being able to accurately control vcore.

As far as which of your vcores is correct, try downloading CPUZ 1.33 (you have 1.30). Or use Asus PC probe II, which I would assume most accurately would read an Asus Mobo.

I've been fooling around with it, and I might be able to offer some observations: if you enable CPU Overvolting, it'll add 0.2V to your vcore setting. So, for example, if you set Vcore to 1.30 and enable CPU Overvolting, you'll get about 1.5V in actuality, but with me it only shows in SpeedFan, not cpu-z.

I'm having another issue now, that is lately, with otherwise stable OCs (afaik), whenever I reboot the system, it will go to a dead black screen. It doesn't happen if I power off, then power on.
