4GB dual channel or 6gb single channel?

post #1 of 6
Thread Starter 
So I'm get a Lenovo X220 notebook with an i5-2410m. Since Lenovo's configuration wizard rips you off when it comes to memory expansion, I opted for the default 1 stick of 2GB. My question is will I see a noticeable decrease in performance if I add a 4GB stick instead of going 2x2GB dual channel?

Honestly, there's a negligible amount of performance difference going from dual channel RAM to single channel. I say go for the 6GB.

It would bother me to not run in dual if I could, loss performance.

I say get another 2gb stick and run dual, 4gb is enough in general anyways.

A 4GiB stick plus a 2GiB stick in that system isn't single channel except for the last 2GiB of memory.

Add the 4GiB stick. There will be no reduction in performance unless you use more than 4GiB of memory, and even then, having the last 2GiB in single channel is going to be way faster than not having it when you need it.
