I am curious as to the different kinds of RAM. I have a computer that I want to upgrade, but I need RAM that has 3 slots in the teeth. What type of RAM is this?

Lets start with what type and make of cpu you have Intel/or AMD or other. Also the configuration of memory slots would help to some degree 1, 2, 3, or 4 long slots and 2 or 4 shorter slots or some variation of this.
As for the different kinds of ram there is 72pin simm memory which needs to be installed in pairs usually unless you have a Compaq which would run on a single stick. There is also 30 pin simm which is so outdated you might as well quit now, also there is older pc66 EDO SDRAM which has 168 pins and 2 knotches. Pc100/133 SDRAM also has 168 pins with 2 knotches as well. DDR memory has a single knotch and is rated at 200, 266, 333, or 400 mhz. Rambus memory was designed for use with early Pentium 3 class PC's and later adopted to some Pentium 4 class PC's and is generaly installed in Pairs like the older simm's but on some systems from DELL and probably others the configuration was single channel RDRAM (Rambus) and was proprietary.

I have an Intel Pentium III processor and it has long slots for memory. Right now my computer tells me that there is only 28 MB of RAM on it and that is why I want to upgrade

Depending on the chipset the memory will be Rambus or PC100/133 SDRAM

Sounds like you have 1 stick of 32 meg sdram with 4 meg being used by integrated video thus the 28 meg memory.

I purchased 256 MB of SDRAM yesterday and put it in my computer last night. I also left in the original 32 MB. When I look at the system properties it says that I have 252 MB (which you mentioned earlier about sharing 4 MB). Why wouldn't it combine the 256 and 32? It acts like the 32 isn't even in.

The density of the memory plays a role in what memory configurations the board will except. My guess is the 256 meg is high density memory and that negates the 32 meg. If windows 98 is the operating system it is just as well as Win98 can not cache more than 256 meg of ram.

It is Windows 98. I will take out the 32 MB of RAM. Thanks for the help. My computer is running incredibly smoother and faster.
