I have seen RAM advertised in two way: In single gigabyte sticks and in 2x512 sticks which equals a gigabyte's worth. Someone told me that the 2x512 will provide dual channeling. I haven't the slightest idea what the significance of this means! What is the reasoning behind the differences and what do you gain/not gain by going either way? I will be purchasing a motherboard that can take 4Gig of RAM. Thanks.

I don't know the term very well, but Google is a friend of mine, and he told me to show you these links for some help.

Hmmm... I don't know much about that fancy dual-channelling stuff, but I can tell you what I do know.
On the motherboard, there are a number of slots for memory. Each slot has a certain configuration (PC2700, PC3200, etc.) that indicates the type of memory it can take. One slot, one stick. That's the way it works. The total of the memory in the slots is the total memory on the machine. 3 slots, 256MB each, you get 768MB. Make that a 512, a 256, and a 128, and you get... carry the one... 896MB. Some motherboards may not support that much matching -- you may only be allowed two types. So... memory sticks have to go into slots. One slot, one stick. You want a gig? You can get it on one stick or two. Having read the first of those links, I'm now more knowledgeable. Dual-channelling is a motherboard feature, and in order to support it, you need to have an even number of memory slots -- not three, like me. You also need a CPU that supports it -- unlike me. And when you get one, dual-channelling simply means the memory works with it -- there's nothing extra special about the memory. One stick or two, it's all up to you. Of course... if you buy one single 1GB now, you can buy another one later and dual-channel it... [img]smile.gif[/img]

Ensure the MB is capable of dual channel. Also, know exactly what speed and type of memory it and the CPU require. Memory is at very long term low at the moment, but, high end DDR2 will still cost a small fortune.
Larry's friend will give you all the answers you need. In a nutshell, 2x512 in dual channel (4 lane highway) will allow TWO passage ways to operate. Where as single channel (a driveway) won't.

To keep it simple, two sticks running in dual channel are faster, but obviously they take up more room, not wont allow you to have your MB's potential of RAM

Thanks to all of you; I understand now. The DFI mobo does support dual channeling, but like you said Hive, dual channeling won't allow me to take full advantage of 4 Gigs of RAM. Larry, read all the articles. Wanted you to know your work wasn't wasted!

Albromor, are you actually going to put 4gbs or RAM into this thing? That's way more than what's needed for day to day tasks, unless you have a specific need for it of course.
2 x 512mbs RAM are better than a 1 gig stick, as they have lower latency times which make things happen quicker, and they are also better if you wish to overclock your computer, in the same respect. But that's a different story. Personally, I would only buy a 1gb stick just now if I were going to buy 2 1gb sticks at the same time.

Ross, no I wasn't going to put a full 4 gigs in because I realize that would definitly be overkill. Let me ask you this: What if I got 2 Gigs at 2x512? In other words, 4 sticks of 512 which equals 2 gigs. Doable?

Albromor, I am glad that those links were of interest. I would have never considered it a waste to have posted them because when you asked the question, I realized it was a term I did not know so I investigated it for myself as much as for you.
I have a MoBo that has to have all four slots filled, and came with two duds just to fill them. That meant that I had to have two sticks of real memory there. I ended up buying four sticks of RDRAM of 256MB each. I have dual channeling and did not even know it or what it meant for me. My memory capacity for the system is 2Gig, if I remember well.

Stick with the 2 x 1gb sticks What was your intended budget for the RAM?
