Air benching my WTF cooling R7 260X

My good old R7 260X from WTF cooling has gotten even more WTF and now does 1450+mhz on the core.

And this is the V mod I did on the GPU. I finally got my hands on a 10Kohm potentiometer so I got the core voltage under manual control. Unfortunately a 10Kohm potentiometer is not enough to keep the voltage in "safe" territory and so the card has a minimum 3D load voltage of 1.47V. The 3rd wire on the back is hooked directly to the + leg of one of the output caps and ends in crocodile clip to allow for easy measurement of core voltage with a DMM.  

                                               Here's a shot of the side of the GPU. You can see both the potentiometer and the crocodile clip behind it

The screws on VRAM in this and the shot above are there to cool the memory because in my first runs the memory overheated and crashed when above 1670mhz. That's a massive problem on a card that has an anemic 128bit bus feeding cores 896 stream processors running at 1450mhz.

And here's the card running in my main system. The Gelid heatsink did a great job and kept the core bellow 70C° throughout my benching session. The Hynix VRAM on the other hand was terrible and kept me bellow the 1600point mark in Unigine Heaven DX11 Extreme.
