| From: Alex Volkov via talk <talk@gtalug.org> | The other system I have is from 4 years ago, based on AM3+ platform, so it's | only has PCI v2 (there's a mention of PCI v3 requirements in ROCm | documentation), probably no exposed CRAT tables, and sketchy IOMMU support. | Just installing the card into it would likely not work, and upgrading the | system to something that will support ROCm stack properly would cost more then | $500, whereas just getting gtx off kijiji would be less than $200. I just assumed that my Haswell systems have PCIe v3.0, but I don't actually know. <https://rocm.github.io/ROCmPCIeFeatures.html> Googling for a way of testing for PCIe v3 from the linux command line isn't too rewarding. In the output of "lspci -vv" I see 8GT/s so I think that I have PCIe 3.0.
