I just ran the tool on my "old" MSI K9A2-Neo with AMD770 chipset and single PCIe slot - Sapphire HD4870 and GPUz says PCIe 2.0 @ x16 - Cat 9.3

All runs crash with GPU Recover when starting the last level of the test but up to there it shows : CPU->GPU 4.1GHZ & GPU->CPU 880Mhz .... I am guessing that is not good?
