4Gb is 32 bits, right ?. You may find that it will work but was never
supported by dec/compaq/hp. For early Alphas, 64Mb simms were
typical at the time, so the machines msy not have been tested
with much larger anyway.

Not sure about pc100, but typical Alpha memory was fast page
mode registered ecc, 3.3v, which was a bit oddball even back
then. Check the spec for the machine first, then see what's
available from the add on memory vendors...
