vddq mod help ( old card) and other questions (way out there ?)

well i have this old v7100 sdr card and have been modding it a little and i have not found a vmem mod for it because the ram voltage comes right from the agp slot

but here is my idea

cut all the traces to the agp slot for the vddq, make jumpers connecting the card side of the cut traces the take another psu turn the 5v down to about 4v and connect all the vddq traces to the psu. i figure since i wont have much to loose 4v isnt to much and it will have water cooled ram and core


could this idea work and if it might whats a good votage to run the ram at. the chip a sammy 5ns ram

also i have the vgpu at 2.5v it will run at 285mhz on air but at this mhz the voltage is only 2.29 under load 2.49 with no overclock though

stock mhz are 175 gpu a
165 mem

also what side is the a side and b side of a card

and whtch is the 1st pin on the pinout

just want to make sure
