I just did a really quick voltmod on my 6800 vanilla.

The ram normally craps out at anything above 860mhz. It is now running 900mhz stable.

w00t!

All I did was put a 2.2k ohm fixed resistor between TP13 and TP14, didn't even have to solder. Stuck the pins through, bent them some, and used doublesided tape on the other side to keep it from moving around and arcing.

900mhz on GDDR1 isn't half bad, I intend on increasing the voltage some more and break 1000mhz on stock 2.2ns timings.

I broke 1000mhz on loose timings before but it yielded worse performance.

This was an easy mod to do :)
