So lets get back to the topic.

An excellent idea.

Where are we at with the voltage mods?

The best that I can tell, and please correct me if I'm wrong...

The current mod is to replace R10 on the Zeus schematic (R7 in nst6563's first couple posts) with a 7.5k resistor.

See posts https://bitcointalk.org/index.php?topic=644921.msg7311585#msg7311585 and https://bitcointalk.org/index.php?topic=644921.msg7407129#msg7407129

There is something in the firmware or hardware the prevents clock rates over a certain frequency. Voltage modded devices are running at a --zeus-clock of 381 (the suspected maximum)

The speed limiter cannot be overcome in the mining software.


Cooling Mods

Cooling improvements are recommended/required for volt modded devices.

See the following posts for examples of fan mods...

I could have sworn there were recommendations for thermal paste and heat sinks for the ASICs, but I can't find them. Might have gone away with the purge.

I think everyone can agree that adding heatsinks to the outside of the case/heatsink will add surface area, but ultimately does very little for keeping the chips cool.
