[n00b] Do I need to buy Dual Channel or is 2 Single fine?

post #1 of 10
Thread Starter 
I am a complete noob when it comes to RAM.

Don't kill me!

What is the difference between buying a single stick of 1333MHz 2GB and then adding another of those sticks after I get the money....and getting a 2X2GB Kit?

e.g.

2GB single:

2X2GB Kit:
http://www.ebuyer.com/product/166995

I am under a tight budget trying to get a new computer...so I would prefer if I could upgrade my RAM in stages, rather than a big blowout.

I'm guessing that there are some rules about how modules won't be identical in performance etc. so therefore there will be some performance loss...but how much? Noticable for a casual gamer/heavy websurfer?


Thanks in advance!

If they are the same memory there is no difference.

You could do that if you really had to. Adding another DIMM in the future, if you add a module with the same frequency (in this case 1333), and the same timings, it would be the same as if you added a 2x2 kit in the first place.

Single channel operation (1 stick) will see a significant memory bandwidth hit though, 1/2 of what dual channel operation could provide. Although in reality, based on some benchmarks done by other OCN members, the hit to the system is only about 3% depending on the applications you actually run.

The thing that put me off was that some RAM I have looked at is only available in for example 2X2GB Kits which put me off..making me think that there was something special about them.

It's just a marketing ploy am I right?

I think it's just more common to buy 2, plus I believe it's slightly cheaper.

Well, if you have 2x2gb, then you still have room to expand to more. If you get 4x1gb, then you've just used up all your RAM slots. I think that's the only difference between them. Using dual channel allows both channels to be used so more data can be passed than through only one channel because... there are two channels as opposed to one. You probably won't see much of a difference either way, but what the hay.

I'm that much of a n00b lol...I can do the basics

I'm looking towards building up to a 8GB climax...adding 2GB at a time lol...

PS. There isn't that much of a saving by getting kits...in my neck of the woods (UK) when looking at cheap generic RAM, there isn't much of a difference, infact 2 separate 2GB modules are cheaper by £4!


Thank you everyone for the great support!

I hope all of you have a Very Merry Christmas and a Prosperous New Year!

If you really do intend to purchase generic 1333 9-9-9-24 1.5V RAM (and for a custom build I highly recommend that you don't) you should be going with as cheap as possible because in this case brand doesn't make a difference anymore. Go with one or two of the Corsair kits, they'll be cheaper in the end. Or better yet, find better RAM that runs at 1600Mhz; it scales better in performance & overclockability and is often cheaper.
