Default GPU-Z, 7970 Crossfire, second card showing wrong PCIe speed - 04-08-2012, 19:03 | posts: 122

While gaming, GPU-Z is showing that my second 7970 is running PCIe 20. 1.1, its actually switching between PCIe 2.0 and 1.1. is this a GPU-Z bug, or what? most of the time, it shows 1.1

The rendertest shows both @ 2.0

P8Z68 Deluxe/GEN3 and 7970 Crossfire
