I think they are 16MB simms. Hope you didn't pay much for them. And if you
got them from a shop, take them back.

perhaps the MB refers to Mega Bits?

It is 64MB RAM.
A quick look at Pentium 1 class motherboard manuals revealed that none of
them mentioned 64MB modules. And another bit of investigation revealed that
64MB RAMs and above require 4x clock. Therefore is the standard boards only
supply 1x clock you will only see 1/4 of the capacity.

   These are descibed in my list as 16Mbit x 4bit units, which means
that 8 of them are 16Mbit x 32bit, which equates to 64Mbyte of RAM.

   This sticker appears to be correct!

   This is not uncommon with some motherboards.  Either change the
SIMMs or change the motherboards so that they match!

    Try them in a late super socket 7 motherboard and you *may* get
64Mbytes.

     OTOH the decode of the part number reads oddly, so they may only
fit a very limited set of units.

     Regards,
           Harry.

Thanks to all who have replied.  I will verify with the vendor
tomorrow.
