System Profiler RAM Slots

[Thiol]

Someone else pointed out in another thread that on the 11" MBA with 4 GB, if you look in System Profiler under memory, the software says that there are two RAM slots. I can confirm that on my MBA. So:

1) Is the same true on the 13" with 4 GB RAM?
2) Has anyone published a tear down of a 4 GB model just to be absolutely sure that there is only one soldered RAM slot? (I know it's unlikely that a second one got crammed in there, but I'd just like to see the tear down picture)...

Yes same on the 13" with 4gb ram.

As for the teardown, i am pretty positive ram is soldiered on.

It's soldered on and not upgradeable. This has been covered. Don't get your hopes up on user upgradeable RAM, it's just not there.

We know for a fact that the 2 GB models are soldered. But to the best of my knowledge, no one has published a tear down for a 4 GB model. I just want to see it to be 100% sure even though I'm already 99% sure.

Why is this so hard to accept? The mere fact that Apple makes all 4GB models CTO is a good indication of that. Otherwise, they would just let the stores add RAM.

And we're all 100% sure.

Can you link us to a teardown of a 4 GB model?

I'm just curious, not resistant. Software showing two RAM slots is probably just a quirk, but it's worth following on I guess.

It's not showing slots, it's showing banks. RAM is often in two banks for interleaved access for faster speeds. Being in physically removable slots is not required for this.

It's 100% soldered to the logic board. No slots, no upgradability.

I didn't know the distinction. That helps. Thanks!
