The 380 has memory on the motherboard, and a model-specific daughtercard for expansion memory.  

It seems reasonable that the Pro bus (I/O card) expansion memory should work in both models, but I don't have any to try that.

If you have a 380 complaining about memory and it has a Pro bus memory card installed, I'd suggest removing that card to see if it's happy with just the stock motherboard memory.
