I then put a low-end X2 into it (also 2200 Mhz and with 512 kB cache) and my build worlds are now twice as fast! :-) SMP does have its benefits. The only drawback was that I had to replace my RADEON card with an NVIDIA due to stability problems in SMP mode. Since I run mostly in 32-bit mode the nvidia-driver port works OK for me. However, that would not be an option in 64-bit mode! --- Gary Jennejohn / garyjATjennejohnDOTorg gjATfreebsdDOTorg garyjATdenxDOTde
