I was oversimplifying significantly.
And, now that I've been out for a walk, to see my wife's mom, it occurs to me that the more likely scenario is the one that I think others have implicitly assumed. That is, that there is enough logic for the controller to *recognize* the 8G stick, but not enough to fully *decode* it. Particularly, if your compatibility table doesn't mention 8G, there would be no surprise if the motherboard were able to see that it's an 8G stick and decode just half of it. And if that's the case, getting a mate to the 8 you have would leave you able to read the lower half (or maybe the upper half) of both 8G sticks, so you'd be able to access 16G, but not 24. And I can think of a particular decoding arrangement where an 8G stick all by itself could be fully decoded, but when you add more in the second pair of slots there wouldn't be enough decode circuitry to fully map both pairs of slots. Thus the need to use a full set of diagnostics tests if you really want to see what's happening. -- Joel Rees Be careful where you see conspiracy.
