Hi Glen

I would strongly recommend add more RAM,more 16GB RAM will worth it in the end as I've been on 16GB previously and then on 24GB and still I've maxed my RAM too,due this I've bought extra 16GB and now I'm running 36GB(4x8GB and 2X2GB,my Motherboard have 6 RAM slots) and I've never been in situation I'm out of the RAM,although in MAX I'm sometimes too close to the 32GB due this I will be upgrading to extra 16GB later this month

And I would recommend to render in separate process which only helps with large scenes there

Hope this helps and good luck

Thanks,Jura
