Does Dual channel matter in this scenario?

post #1 of 6
Thread Starter 
So a friend gave me this stick of RAM he didn't need.
I know it's overpriced on the site but I got it for free so who cares.
http://www.bestbuy.com/site/olspage....=1200703058743

Now I want to add it to my existing system where I already have 2x1Gig Mushkin Ram in dual channel mode? Then I would be adding one 2gig stick that doesnt run in dual channel. Is it worth it?
I know the best way of having 4gigs is to have 2x2 but I'm just curious how this would work out.

Also does anyone know if this model overclocks well?

Dual channel can make a whole lot of difference depending on the situation.

This test should help you decide.

EDIT: Although that test is run on an AMD machine where the memory controller is on die. I don't think dual channel makes a whole lot of difference with current Intel cpus since the memory controller isn't on die.

Thanks. I understand the advantages but my question is what affect would I get adding one 2gig stick of memory to my existing 2x1 setup?

imo, more ram trumps dual channel. In that setup, I'd go for it, especially since you got it for free. If you end up not liking it, you can always take it out.

Install it and benchmark it to find out.

Some motherboards (I know the 790i chipset does this, not sure about yours) can run memory channels seperately. So you'd have the original two sticks still in dual channel mode and the leftover stick in single channel mode.

I'll look into it.
