Hope this helps.
Again, the highlighted portion is NOT TRUE.
On every motherboard I've tried it on it depends on which slot which card is in.
On my current board, the top slot is master so, if I put a card in that slot clocked @ 800mhz and a card in the lower slot that's @ 600mhz the card in the lower slot automatically OVERCLOCKS to 800mhz.
If I switch them and put the 600mhz card in the top slot and the 800mhz card in the bottom the bottom one will then under clock to the slower speed of the card in the top slot.
It's a basic Master/Slave hardware configuration.
