It voids the warranty, though.

"the lousy stock turbine" is really efficient, the only way nowaday is something like this

Crazy, they sell what they call a "Gaming Supercomputer" with up to 4 Titans!!! I wish I was really really really rich:

Sounds somewhat like a toxic mortgage...

Sign up for Amazon EC2.

You can spin up two, and more, on demand.

The world is changing.

Sadly, not all are ready for change.

It's too bad the Kepler cards are so inefficient at trial factoring. In comparison, the three-year-old GTX 480 cranks out 373.6 GHz-days/day (according to James' benchmark page) with a mere 480 cores at 700 MHz.

[QUOTE=Redarm;332510]8 hours without error (but also decreased memory clock to 2500 Mhz)[/QUOTE]

Cheers. Thanks for idea.

Trying 2500 mem clock on a double check with the -t option.
