Would it say on the Stick? Because I don't recall it saying it on there, I just know the shape of my RAM... I believe it has 2 Notches, I'll have to check again.

Two notches generally is the key for SDR (one near the centre and one over toward one side), but I haven't looked at RDRAM lately... anyone with a P4 with Rambus know what key it uses? Two notches at thirds? One notch? I believe that DDR is a single-notch key near the middle.
Additionally, though you normally have a sticker, the PCB should also be silkscreened at least with an FCC ID, which you can look up to find manufacturer. If you just need the specs (response speed most notably) you can just copy down the ID information from one of the individual chips on the stick, and look THAT up.
There are 3 major types of RAM in use today: <a href='http://www.atmarkit.co.jp/fpc/pcmainterepair/pcmr003/sdram_dimms.jpg' target='_blank'>SDRAM</a> <a href='http://www.mikhailtech.com/articles/memory/crucial256ddr/crucial256ddr-03.jpg' target='_blank'>DDR RAM</a> <a href='http://www.tomshardware.com/cpu/20020402/images/speicher.jpg' target='_blank'>RDRAM</a>
There, your RAM will most likely be one of those 3 types. However, there are alot of variances in those 3 types (speeds, ECC, etc).

Check this <a href='http://www.crucial.com/store/listmfgr.asp?cat=RAM' target='_blank'>Linkeh</a> and fill out your Mobo maker/computer maker.
