Any ES40 with fewer than 4 memory options installed (i.e. 8GB _minimum_) is a huge waste of space, energy, and money. With just 2 RAM options installed (i.e. 4GB minimum), the machine is way under-utilized and can only achieve 1/2 its memory throughput. With just one RAM option installed (i.e. 2GB minimum), the machine crawls at 1/4 its potential memory throughput. There are many better, faster, cheaper, smaller, types of systems available if one does not need to break the 4GB 32-bit address space boundary. I.e. I guess FreeBSD doesn't really truly support the ES40 (or anything bigger) at all. You should definitely not list them as supported! I'm sure anyone else familiar with Alphas would make the same assumption as I have that the full RAM configurations of any supported machine would work -- that's the whole reason for wanting a 64-bit address space in the first place! > But surely not on 16G RAM. BUT, that's only half-way to where we want to go with 32GB installed... -- Greg A.
