Wish I could optimize the memory in my head... Anyway, my initial results were: P4 2.8(3.09)Ghz 1GB Ram Win2K 209 seconds I got a couple of lookups in Max, though, so I ended the 10% overclocking. However, I did play around with my DRAM settings, it turned out they were (in "auto") 4,4,8 CL 2.5, I changed that to 3,3,6 same CL, same burst length (8). New time is: P4 2.8Ghz 1GB Ram Win 2K 194 seconds, an 8% improvement that didn't cost anything. Hopefully, this will be stable (2,2,6 CL2 would be "radical", maybe I'll try that later if this seems O.K. after a week or so. Now to make some kind of a list from all these results!
