I have a computer with 2× 1 GB DDR3 1067 MHz RAM modules. Now I bought 2× 2 GB DDR3 1600 MHz modules.
- Should I remove the 1 GB modules and use the new ones only (2× 2 GB = 4 GB total)? The new modules are faster and I will keep the dual-channel.
- Should I use all of them (2× 1 GB + 2× 2 GB = 6 GB total)? The thing that worries me is will I lose the dual-channel mode if I connect them like this? Also, won't all the modules run at the lowest frequency (1067 MHz)? Will this decrease my performance a lot?
Which combination of modules will give me the best performance?
