Hi, trying to piece together some old systems. Can't seem to identify a stick of RAM. here's the rundown.

Definitely 168 pins, so it has to be a DIMM module.
Not sure of the bus, probably PC100, but could be PC133.
Total of 32 chips on the PCB, 16 on either side. This could possibly mean it's a 32 meg stick, right? I thought originally it was 64, but who knows.
The stick is LARGE, rather cumbersome. Two rows of chips upright.

On each chip the following is printed...

SEC KOREA 813
KM44S4020CT-G10

TQA702EB

There is one extra chip on one side of the board, and it has the following information on it.

PI74FCT
163244AC
Z9803FOC

And that's it. I remember this being in an old AMD 300mhz system a while back, but I'm not sure now. I would pop it in and try it, but I am afraid I will blow it up or somthing because of voltage settings and whatnot. That's kinda why I want to figure out what it is before I shove it into somthing. Isn't there some sore of FCC serial number or somthing I can enter into a database and find out some information? I used to have that link a longtime ago, but I can't find it anymore. Any help would be greatly appreciate, thanks!

You won't hurt a computer by putting the wrong RAM into it.

Turn it on, it will either POST fine, or beep a few times which means it won't work.

See if there's any lettering/numbering on the PCB itself. Could be RAM, or a COAST module or a removable L2 cache.

You can also Google for some of the numbers. This is what I got on a search for KM44S4020CT:
