The math doesn't go in the 450:300 case.

Results from benchmarking indicate that 450 in the 300 case is actually 1:1 and that "600" in the 300 case is actually 4:3 == effective 400 MHz (800 in DDR speak).
Probably because DDR2 doesn't exist at lower than 400Mhz rated ddr2 frequency.

(300/4)x3 = 225 x2 (DDR) = 450Mhz

Works to me

4:3 on 300mhz isn't 400Mhz, that would be 3:4....

I don't really understand you. Higher mhz = higher bandwidth. What are you comparing to? 975x memory performance is a lot better than other chipsets.
