I bought a used Acer Veriton X4620G. I'm using 64-bit Windows 7. It has four memory slots and came with one 2GB module. I bought a second 2GB module and two 4GB modules, for a total of 12GB. It is working and showing 12GB. Belarc Advisor shows 4GB modules in slots 1 & 2, and 2GB modules in slots 3&4.
I need to know if I have them paired up correctly. The user's guide shows how to install them, but it doesn't give the info I need. And sometimes the slots are in orders such as 2, 1, 4, 3.
How can I tell if I have them paired up correctly?
