What kind/type of ram goes into a Gateway MFATXSTL EL2 500L?

As far as I can tell it probably takes pc2700 ddr memory

though some P4s use pc133
Does it have something like this on the case:
PENIV1600/256/20GB/1.44MB/S/CDRW/56//10-100LAN/USB/

If you can see the memory slots, how many bumps are in the channel? or notches on the old ram?
1 bump is DDR
2 bumps is PC133 SDRAM

I found that article too. However; that computer is ELP 500C. and my computer that I am trying to fix is EL2 500L. I do not know how close those two models are, knowing Gateway there is none. I have not found any reference anywhere as to what this particular model takes. I had robbed peter to pay paul and now my manager wants peter running again. Its killer because this computer came with 98 and had xp installed. I had installed ubuntu after the fact without issue, but most of our network machines are Windblows. I think I have the drivers, but as I mentioned before....they are rather difficult to find nowdays. .....So anyways, I will go find paul and confirm. It is DDR by the way...and your guess is definitely good as mine. I will check back as soon as I know and accept the solution. I will know tomorrow. Nice having another set of eyes out there. Thanks

go to http://www.crucial.com/

scan ur computer and it will tell how which type of RAM needed so that u can upgrade it

My manager decided to scrap it anyway. but Coral lead me to the same place I had been. Rather than taking the other machine offline that I put the borrowed ram into for a machine not supported (in any way shape or form (Windows 98)) and Gateway not giving a response at all...I chalk it up to a learning experience and Coral47 is knowledgeable. thanks dude

Thank you much.   : )
