My motherboard says "DDR1 DDR2" next to the two RAM stick holders. The two holders are identical, and seem only to fit DDR1, though.

Does it simply mean "DDR holder #1" and "DDR holder #2"? Because I'd really like to fit a DDR2 stick in there.

Here is a picture:

I read it as "slot 1" and "slot 2". If only DDR1 fits then it's highly likely it was still just called "DDR memory" at the time the board was made. – ChrisF Jul 25 '12 at 12:10

You are correct in your assertion that they are simply identifiers for the RAM slots. It is not possible to have 2 differing RAM types on a single board.

Exactly.............. +1 for that – ichathan Jul 25 '12 at 12:49
Motherboards that support two different RAM types are rare (and that's not what's happening here), but they do exist: picture, article – Dennis Jul 25 '12 at 13:27
Interesting, i wasn't aware of that. It seems you're right, there are a few boards that support DDR2 and DDR3. – Oliver G Jul 25 '12 at 13:28
