Questions about RAM.

[sdfsaasdf]

1. Do all computers come with more than 1 RAM slot?

2. Is it always better to have 2 sticks of RAM compared to 1? I heard that if you get two sticks of RAM that are different speeds (128 and 256) your RAM will only run at the 128 speed. So I guess you would have more RAM, but it wouldnt make your computer any faster, is this correct?

I think it will be quite difficult to find a mobo having only ONE RAM slot.

128 and 256 are NOT the speeds, rather they are their storage capacities.

In Dual Channel Memory technology, it is better to have two sticks-preferably of the same capacity and speed. Otherwise, i don;t think there is any benefit of using two sticks instead of a single one provided the total capacity remains the same.

Motherboards with only one RAM slot are more common than you might think. The "off-the-shelf" manufacturers have tried from the beginning to design the cheapest computers possible, with barely enough hardware to be actually called a computer, and sell them to an unsuspected and computer illiterate public. That's why onboard video, audio and modems were designed...

Gateway made an all in one box with a Celeron 400 and one memory slot. Sony made a Vaio just a couple of years ago with I think about a Celeron 700 or 733, 32MB RAM and a slot in front of the case for add-on memory. I'd bet Compaq made more than one, but I don't know of any that I've seen personally.

If you go out and simply buy a motherboard, no, most will have 2 or 3 memory slots. Most build your own parts are a little higher up the ladder...

One 256MB stick of RAM would actually be better than two 128MB ones, the OS has the full 256 to access at one time, or 128 then go looking for a place to find more...in other words more efficient. Keep in mind we're talking nanoseconds, you won't notice the difference..
