Well using 50% fan speed and then run the render test on GPU-Z wait 5 minutes for it to settle and then jumped up the volts and the temps did indeed rise, so it would appear to be working, down side tho could not get past my best overclock on stock volts which was plus 130 on the core, so im guessing that hitting my limit on the GPU, still it was worth a try, thank you
Did you use the Gigabyte BIOS or is yours the reference WF model? In truth, I would be cautious of doing the mod on air cooling and if under water, I guarantee you will get higher clocks with 1.3V at your disposal.
