Thanks for your reply! And did NVIDIA GeForce GTX 1080 (8GB GPU RAM) report “RAM not available”? I tried NVIDIA GeForce GTX 3070 (8GB GPU RAM) and 32GB RAM, but it reported this error. So I am finding a machine that can satisfy RAM requirements (3DFlex train job - RAM unavailable - #2 by apunjani) and not GTX 4090 at the same time.
