I have a brand new MBP 13" with Dual Core i5 2.5 Ghz, 4GB DDR3 RAM and 500 GB HDD. It runs smoothly but I have been intrigued by the fact that both the memory slots are in use all the time even when I'm doing very light work in my MBP. Is it normal or is there a problem? My HDD has enough space left (around 430 out of 500 GB).
MacBook Pro, OS X Mountain Lion, 13" 2.5 GHz Dual Core i5, 4 GB
Nothing wrong, that's the way things are supposed to work. Normal & all is OK.
Thank You! May I ask you why is it that both slots are being used even when I'm doing nothing heavy duty at the moment? I'm going to upgrade to 8GB after 4-5 months. Is it going to show the same even then?
Your computer uses matched pairs of RAM & both will always be in use. Worry when one slot stops working.
So then even 8GB of RAM(when I upgrade) will show 'currently in use' for all the slots? And does my MBP tell me when one slot stops working?
Yep.
If one slot fails, your computer may not even boot. Your computer is fine...enjoy.
Let's hope that day doesn't come anytime soon!
Thank You once again and have agreat weekend..
Some models have more slots, and they don't all have to be full ("in use"). My Mac Pro (tower) has eight slots, six used, two empty and available for expansion.
As I already mentioned, I have 4GB. I know that's standard now but should I be worried about not having free slots? I will be stepping it up to 8GB in a few months.
Ignore markwmsn's post, doesn't apply to you & did nothing but add confusion. Your computer shipped with both slots full, and is designed to run with both slots full. Will it run with only run slot in use...yes. Is it designed this way...no. Your computer will have the best performance using matched pairs in both slots, as designed.
Are my memory slots supposed to be 'currently in use' all the time when I turn on my MacBook Pro?
