Anyone having luck with the correct CPU voltage on K8N NEO2 Platinum?

[IHYLN]

Been trying like hell to get past 1.63v on the MSI K8N NEO2 board. 10% on 1.55 should be 1.7v but it undervolts to 1.63-1.64

this severely limits my OC as I can sometimes hit 2700 and sometimes I cannot so I'm stuck doing 2600 when I know this chip can do 2800 watercooled at 1.7v

I looked up voltage mods and all I found were VDIMM mods and nothing on vcore

any ideas?

edit: I have an antec 430 truepower power supply btw

any ideas? I'm probably going to ditch this board when I can get a better nForce3 motherboard

I went and flashed my board to the 1.2 bios and I get better voltage readings. At least 1.85 gives me 1.77 and I can run a bit more stable now.
