Yes, FH tasks require a lot of RAM. And I think it increases over the duration of the task. So longer tasks need more RAM by the end. This is why I have been recommending for *years* that people should have at *least* 2gb per thread, for any cruncher. There are always a few projects that need lots of RAM, especially the medical projects. So don't skimp. I target 4gb per thread. This comes in very handy when running VMs. So I can run FH tasks in the VM, as well as natively.
