Initial testing of this card did not go over all that well. While the memory was able to hit an impressive 860mhz with the core speeds at stock, the maximum speed the core could do was a mild 610mhz, a 30mhz bump from stock speeds. Somewhat discouraged by this, I poked about on how to change the Vcore on this non-reference PCB. After some help from the ever helpful guys at XS.org, I learned that soldering a variable resistor between an IC leg and ground allowed changes to the voltage.
