Anybody know how I can find a motherboard that supports buffered memory? Internet search not yielding anything . . . everywhere I look it's, "un-buffered memory."

Did a search for, "compatibility with buffered memory," got zero results.

 

Wikipedia calls it Registered Memory. Maybe search for that?

 

This from a computer memory manufacturer:

"0 results for 'buffered"

Komputerbay, however, did return several results for the seach phrase mentioned . . .

Now I need to find a mobo that supports it . . .

 

Can you articulate a reason why you think there should be a motherboard that supports it. AFAIK it offers no particular advantage, and I'm pretty sure there is no way to accommodate both types.
Most of the online articles I can find on the subject are over a decade old. The industry may have moved on.

Registered memory is more commonly used. Motherboards intended for compute servers will support it.

 

Most server boards used ECC memory, which is "buffered" or registered. Standard home PC types of motherboards do not. If you have this ram already and are looking for a motherboard, search for ECC when looking for motherboards. There are many of them on Ebay. I would suspect you have ECC ram chips.
