I'd looked into using the second slot ( PCIE 3 ) before but the manual says not to do it whereas the printing on the circuit boards seems to say it's ok at 8x. It's only a 7600 GT so 8x wouldn't be a problem.
I thought I read a thread previously on here about an sli mod but didn't want to void my board this early anway, I also remember something about special drivers.
Anyway I took the plunge and moved the jumpers thinking if it doesn't boot I'll move it back or have to settle for 2x.
It booted fine but one section of Everest says there is nothing in PCIe3 Motherboard/Chipset/Southbridge
PCI Express Controller
PCI-E x16 port #0 Empty
PCI-E x1 port #1 Empty
PCI-E x1 port #2 Empty
PCI-E x2 port #3 Empty
But I found this in another section Dipslay/Gpu tab
Bus Type PCI Express x16 @ x8
Is there something else I could test it with?
Thanks in advance
