Well, I get 46.5s on my P4 3.0GHz HT 800MHz FSB (stock, not OC'd), 1GB (2x512 Dualies), P4P800 Socket 478.
HOWEVER, I think this is a terrible benchmark for Hyper-threading machines, check out my CPU usage !! Only 50% !?!?, the rest is idling. Definitely a pointless test if you have HT or a Dual-Core Intel as I'm testing half my CPU versus a complete core of a non HT... When I try calculating more digits my temperature harldy rises
