Nice to see the jumper actually works.
Could you check if your Samsung vram is 1.0 or 1.2ns?
The voltage increase should be of 0.5 which can be reached by simply modifying the BIOS
Anything higher is only reached by hardmods.
I just asked at xtremesystems how to measure vcore with a multimeter in this PCB,
as soon as my card arrives I'll check the voltage increase.
It doesn't say on the RAM itself, not sure how to check it otherwise.
