i have a gen2 75t captain DMA, my GPU is mounted verticaly so i had to use a riser cable, i got one from amazon. Pcie x1 gen4 .. but now the dma isn't working, everytime it shows a different error :
FPGA: TINY PCIe TLP Algrithm auto-selected
and
VMM INIT FAILED
and the only time it worked by some miracle .. the speed test failed.
Can anyone help ?
