I have looked at the spec sheet and it looks like the vid1 to vss will give you 1.6v core. If This is wrong someone please correct me. I am not sure about your mobo but I believe you can change the voltages some in bios. from the posts I have seen you will need something like 1.65v-1.75v plus some good cooling. I have been told that the 1.3a is hard to get past 124fsb or so. I will be doing some testing myself in about a week on an abit vh6t mobo. I am currently running the same chip on a cheapo Msi 6831 at 112fsb or 1456mhz with no volt mods @ 35c under load, very stable. I will let you Know how mine does, maybe we can compare notes. Good luck
