6 cards is no problem with the celeron.

The cpu bug was fixed in release 4. But you need to add 16 gig of virtual memory.

There is also a bug in the hashrate displayed. It sometimes show 14x and sometimes 16x. The real speed is probobly around 150-160 but depends on the clocks. Because of the bug in the original code I work with the nvprof profiler to time the kernel, so the speedup is real.

Release #5 will be spread for free to the donators.
