Some apps don't report the use of both clock edges or the multiplier effect of how many bytes on the buss.
I can't hold a class in computers here but some docs call out 4 bytes on a buss times 200 would be 800 compared to a single byte buss.
There may be nothing wrong at all here.
I'm tryin gto optimise my computer with the P5GD1 Pro motherboard from ASUS.
The issue I have currently is the Bus speed whcih I belive is rated as 800MHZ but shows as running at 200MHZ.
I'm no Guru, but can this be sorted through jumper settings or something?
