after playing for months ddr3/45nm
i do feel that less and less effective on tweak a 45nm/ddr3 system.
dont know if someone have the same feeling as I do.

here is 445*9=4G pi_1m/32m & 450*10=4.5G pi_1m/32m results.

maxmem=624m, largesystemcache=1, non-pagefile, copy waza 1.36G.


1) 445*9=4G 1m = 11.468sec


2) 445*9=4G 32m=11min00.562sec



'coz of FSB limited, so it seems damn hard to break 11min
---------------------------------------------------------------------

3) 450*10 1m=10.219sec (can break 10.1sec ?)



4) 450*10 32m=9min59.531sec (just break 10min, any possibility for 9min55sec ? )
