Re: How high can you get

What about Tetra cards then?.. LordMike I'm not sure if you meant to imply this or not, but you may be on to something! Nvidia Tesla cards may not be considered video adapters, they don't even have a video cable port. If that is the case you may be able to have a machine with 4 GTX 295s and 3 Tesla...

Re: GPU overclocking to increase hash/sec

Bars, maybe make a gpu cracker, that goes through 200-500 Million hashes once overclocked.
Then once not overclocked, do the same process and check if the results are equal.

If not, errors are possible. If so, overclocking is valid.

Wouldn't it make more sense to dynamically allocate the necessary number of threads? Then you can say "no limit" or more correctly "limited by hardware, drivers and/or operating system."
