Am i going mad, or is this wrong Running the render test, it only goes to @ x16 2.0, shouldn't it be @ x16 3.0 ? Checked the configuration in the BIOS, all slots are on Auto, and all i can select is Auto, Gen1, Gen2. Im sure it was @ 16x 3.0 when id checked it after just getting it all up and running. EDIT: Very strange, ive sorted it, now reading correctly @ x16 3.0, went into the BIOS, System Agent Configuration > NB PCI-E Configuration, and changed the PCIX16_3 Link Speed from Auto to Gen3. Don't know why i had to do that though, odd.
