Unidentified memory module

The chips (marking: KM44V16104CK-6) are 60ns (the -6 part) and 8Megabytes each:

* http://freepages.misc.rootsweb.ancestry.com/~wb4kdi/PC/Cobalt/


So to find total capacity, multiply how many chips are on the module by 8MB: (16Mbit * 4bits) / 8bits per byte = 8MB (not Mb)

They are DIMMs (168pins, data/address lines on both sides), EDO (refresh listed in above pages) and a neophyte would say that they could either have been used in various "servers" or PowerMacs.

However, they're also 3.3Volts, which tells me they were *NOT* used in PowerMacs, as they would have fried since they only used 5V modules :-)

Thus "server" RAM.


The "other" chips (74FCT 163244CPA) are inconsequential:

@pyrre:

It sounds like 128MB.


@Zac67:

Nice! Thanks for the expert opinion on the buffering chips!

BTW, I have EDO DIMMs (4MB->32MB) for 9xxx series PowerMacs. Let me know if you're interested.
