I think that's due more to the increasing number of slots. We just bought a Dell PE R710 and it has 18 slots, so you could go all the way to 72GB using 4GB modules. By contrast, the Dell PE2950 gen III only had 8 slots, so maxed out at 32GB with 4GB mods. Ryan M.

Agreed the price gap is just a bit too much going to that next level, but it's dropping slowly. We just got a Dell R800 (?I think that was the model) and when pricing the 64GB RAM it was actually almost an affordable and cost-effective option, but I don't remember if that was still cramming it full of 4GB chips or if it stepped up to 8GB chips.
