If possible could you send me a copy of the factors for a range of about 5G or so for double checking? Email address is in the README file.

Also, are you able to compare that with the 32-bit binary on the same machine? It is possible that the 32-bit SSE2 code is faster than the 64-bit code, and if that was the case then I could probably improve it using 32-bit SSE2 together with the extra SSE registers on the x86-64.
