XFX 4830 vmod?

[Ket]

That IC is uP6101BU8 VG(I think)8B6. Last 3 are real tough to read. Default GPU voltage is 1.25v according to the vBIOS, and memory is Samsung -HJ1A, so a vmem mod to 2.1v should see them doing 1100 easy. Bit puzzled about the GPU clocking so low with 1.25v. BIOS modded voltage to 1.17v and the GPU clocked exactly the same.. so I'd guess the GPU is actually getting 1.17v and not 1.25v.

ED - If someone can verify where I think GPU and vmem read points are i'll get some exact numbers with my multimeter.
