DISCLAIMER: I am not asking if my particular motherboard support 32GB DIMMs; I'm asking a general question about large-capacity DIMMs.
Does anyone know what is technically required for a motherboard to support 32GB/64GB RDIMMs or LRDIMMs? Obviously the CPU (with integrated memory controller) and presumably also the chipset, but what else? Is there something at the BIOS level that is required to support these? Is there some other physical design/component required (like extra copper in the memory traces to handle higher memory loading)?
I ask because there are a ton of motherboards (OEM and otherwise) that list support for 16GB RDIMMs but make exactly zero mention of support for higher capacity DIMMs. Importantly, no manufacturer explicitly states that 32GB DIMMs won't work; they simply list what does work, and from this it isn't clear whether the implication is that 32GB DIMMs physically won't work or merely that the manufacturer hasn't bothered to perform validation testing...
While I'm generally of a mind to just try it to see if it works, 32GB DIMMs aren't cheap and I'm not keen on paying a 15% restocking fee + return shipping on such an expensive component.
Thanks
