Hi, Does it matter to use a PCI-e x16, x8, x4? I have a Asus P5k with 1 PCIx16 and 1 PCIx4 Can i use it with a 4870 and a 4850? Will it be faster with 2 PCIx16 or 2 PCIx8? Thank you Eric |

Now I'm crunching with two ATI4850 in a PC with 2 PCIe x8 and I'm getting approximately twice the credit that I got before, when I was crunching with one ATI4850 in a PC with one PCIe x16. |

This host has 2x hd4870 on an Asus Commando with PCI-E v1 x16 / x4. I can't see any difference in the crunching times. |

I have a Asus P5k with 1 PCIx16 and 1 PCIx4 Hi, I have the same board, don't worry about the bandwidth as you are using the GPU only. Overall you won't see any performance benefit for switching to 2x16x, although you will if you're gaming. If anything the board is perfect as you're not wasting money for the dual 16x premium. Just put you 4870 and 4850 in without crossfire and you'll be good to go. Happy crunching |
