2011 2.ghz MBP with 240gb SSD. With just light duty, will there be a significant difference in speed using Safari, iTunes, etc?
if you are going from a HHD to and SSD it will be a significant difference in speed. For RAM how ever you will not see a speed change in the same way with light usage. If you use a lot of taps and different programs at the same time RAM will give you a perceived speed bonus as more active files is kept on the fast memory and is not moved to the SSD as often (swap). Personally I think a 8GB is a really nice spot for a light duty machine as you in many cases would not hit the limit daily and have some additional space if you need memory intensive programs (photo, video, some games and such).2011 2.ghz MBP with 240gb SSD.

Considering he said light usage and it is a 2011 machine I think 16GB might be overkill.If you go the halfway "8g route" you will later have to replace both chips again to further upgrade to 16
Any downside to only running one chip vs 2 chips? 1x8gb vs 2x4gb speed wise?Considering he said light usage and it is a 2011 machine I think 16GB might be overkill.
A way to go the halfway route if one is considering upgrading to 16GB in the future would be getting 1 8GB slot and install it with one of the existing RAM moduls.
A little since it is dual channel, so you will lose 1 channel which could affect speed. But you should be able to run 1x8GB + 1x4GB and have a total of 12GB. From what I can find this should not be a problem at allAny downside to only running one chip vs 2 chips? 1x8gb vs 2x4gb speed wise?
Thanks. I currently have 2x2gb chips. Would 1x8 and 1x2 be an issue?A little since it is dual channel, so you will lose 1 channel which could affect speed. But you should be able to run 1x8GB + 1x4GB and have a total of 12GB. From what I can find this should not be a problem at all
That should not be an issue either.Thanks. I currently have 2x2gb chips. Would 1x8 and 1x2 be an issue?
Perfect, thank you.That should not be an issue either.
as long as all the other things on the ram are the same a drop in performance compared to 2 identical RAM should be negligible.
Edit: An old thread here discussing it. Consensus is that if there are a performance difference it is not perceived
