I have been building a custom setup for Deep Learning and my specs are as follows:
CPU: i7 8700k
GPU: 2 * RTX 2070
Motherboard: Aorus Ultra Z390
PSU: 750 W
I installed the latest Nvidia drivers along with CUDA 9.0 but running nvidia-smi shows only one GPU. I swapped the GPUs and still only one is detected so there is no issue with the GPUs. The undetected GPU is in a PCIe x8 lane and it lights up and the fans work. The third PCIe lane is x4 so it is not possible for me to test the GPU with that. I tried with Ubuntu 16.04 and 18.04 along with linux kernel versions 4.20,4.15 and 4.9 but none seem to detect it. I do not have a SLI bridge connected but that shouldn’t prevent it from being detected I guess. Could anyone please help me out?
