i just bought the MSI K9A2 CF, and got only one gc: HD3870 IceQ3 The problem is that the first PCIE slot to near with the SATA port, if i place the GC at the first, i cannot get 2 out of 4 SATA port. I need all 4 SATA port to be used. So, i put the GC in the second slot, boot up and it run properly. When check at CCC, "current bus setting: PCI Express 2.0 x8". How can i change it to run at x16 speed??
