I was getting about 1000 mbs with sdram @ 160mhz, fastest timings. Popped in samsung ddr 333 in there and ran at 160mhz(320mhz ddr) and i only got 1600mbs with the fastest timings. That is really low considering it get beat bad by via kt266a @ 266mhz ddr and Ali Magik 1 @ 266mhz ddr, which is the same chipset! Running on a t-bird 1450 @ 320mhz fsb x 9.0, samsung pc2700 @ 320mhz ddr, Asus A7A266.
