I recently did the pencil Vmod on my x800 pro.
At 1.7v I've managed to push the core to 630mhz.
Temped to go higher, but satisfied for now.

I have a question for you guys that have done this mod though.
If you measure your Vgpu when running...say Ati-tool, does the voltage drop on you?

Mine loses a few hundredths when running ati-tool, but when it does the "heat-up", it drops around .1v

I'm trying to figure out if my PSU is crapping out, or if this drop is normal.
