Reply to comment by vade in I have 6x3090 looking to build a rig by Outrageous_Room_3167

>I run 3x 3090 in a single case, without water cooling, but using one PCI riser and keeping the case open to allow for airflow. This is on a single 1600w PSU, no NVLink.

Oh sweet. So maybe we go the route of 2, 3x3090 machines. Might be the better direction. Was considering 2000W PSU & 4x3090. How much memory & what CPU are you using?

We have a Ryzen 3950 max ram (128gb) - but I’d like to get a system that supports more ram and 16x on all pci slots. But alas - $$$

Isn't that amount of RAM good enough for the setup? Or you think it's a bottle neck in the training, just new to all of this :)

It’s fine - we haven’t had a huge issue due to it but we work on video related projects so memory is always a boon. That’s all!
