Solved Slot numbers and RAM relationship question Tags: Memory RAM Notebooks Lenovo Last response: December 8, 2012 3:29 PM in Memory Share shaltzer December 7, 2012 5:12:52 PM I have a notebook Lenovo G450 with two slots. The max RAM for the notebook is 4GB. I already have 2GB RAM installed at slot #1. I'm planning to upgrade the RAM into 4GB. The question is which is better between these two options? 1. Add new 2GB RAM at slot #2, so total RAM is 2GB + 2GB = 4GB 2. Replace 2GB RAM from slot #1 with 4GB RAM, so slot #2 is empty.

However, it is always suggested to use MATCHED pairs of RAM. So out of those 2 options getting 1 4GB stick and putting it in slot 1 would be suggested. Either that, or replace the 1 2GB stick you have with a matched set of 2 x 2GB sticks. Performance wise, you will see no difference.

Which is nice, but usually doesn't make as big of a difference as you'd think. m 0 l Can't find your answer ? Ask !
