|"when I change my system memory multiplier to 3.2 it shows my ram freq at 1066MHz and CPU-Z reports my dram at 533 with a ratio of 5:8"|
Don't confuse the DDR rating with frequency. Your RAM does NOT run at 1066MHz frequency, it runs at 533MHz frequency. 1066MHz is the double data rate, which is frequency x2.
Obviously 5:6 and 5:8 aren't 1:1. You need to change the memory multipler to 2.0 to get the RAM to run at 333MHz. Or better yet, crank up your CPU frequency to 400MHz (1600MHz FSB) & run the RAM in sync at 400MHz (800MHz DDR).
