DFI LanPart UT NF3 Ultra-D voltage settings??

[imported_ThEThInG]

I'm ocing the cpu, a 3200 winnie, and i'm a bit confused aobut the voltage settings in the BIOS, there is two different settings that affect the cpu voltage, one varies by .1-.9(which i currently have on .3) the other varies normally like the vcore settings on the Asus A8V i had, which i currently have set on 1.475v. Now CPU ID reads 1.520~1.508, under full loads, which is pretty stable, i have a pretty good PS(OCZ Power stream 520 w), voltages are pretty stable. But why are there two different voltage settings? Is on for the onboard memory controller of the A64's or something like that? If so, why would my Asus board not of had that? Any input would be appreciated.

I'm confused, there were no Winchester cores made in Socket 754?

SKT 939 buddy, the NF3 Ultra is a 939 version of the NF3 250 GB, that was the big difference in the chipset, solid performance moved to 939. So is the Asus A8V Deluxe with Via's KT800 Pro chipset for 939 cpu's. Remember this is older hardware, I got all this stuff about a year ago, SLI just started coming out and barely worked because it had so many buggs.
Remember the reviews of the NF3 SKT 939 roundup? With MSI, DFI and some one else being the top ocers? Back when winnie was first 90 nm production of A64's, it was the latest and greatest overclocker at the time. I'll be upgrading the CPU to a 3800 X2 in a coulple of months, but I want to figure out these weird voltages so i can oc easier, i had to guess with this setup and was lucky to find the right combo.

Ah, sorry. Bump for an answer!

I believe it's to fine tune the voltage so you're only using what you have to so your overclock is stable and heat is kept to a minimum.
