Default Leadtek Geforce GT 220 Extreme Overclocking Experiment

We pour some -180C LN2 over NVIDIA's 40nm GPU to see how high it will scale. With the help of some voltage modifications we are ready to breach some world records at the low end of the video card scale.

John, could you attach both PDF's to this thread? People who are no OCTB-member can't seen the voltmod thread.

Thanks.

I'm actually tempted in buying another GT220 to check for overclockability :-)

Interesting read.

Since the memory chip temperatures are obviously holding the core/shader speeds back, wouldn't it not be very hard to jury-rig an inverted peltier block, hot side on the chips? Wouldn't take very much, adjust the peltier voltage as needed to keep them just above zero centigrade... perhaps with a pot that allowed extra spacing. Or direct heating the other side of the PCB directly underneath the memory solder points, sort of like an inverse waterblock for the memory if it could be insulated from shorting.
