And from black ones (physical x16) too. So, Lord Trident, one more menu with a choice between all 4 psysical x16 pci-e slots will be just fine :
PCI-E1_16X and PCI-E2_16X support 8GB/s (16GB/s concurrent) bandwidth
PCI-E1_8X and PCI-E2_8X support 2GB/s (4GB/s concurrent) bandwidth
And thanks in advance .
