I have a 1721 with 32MB onboard. It will handle up to 128MB. If I
put in a 128MB SDRAM will this work? IE will the extra memory be
ignored? There are 96MB SDRAM's available but they are somewhat
pricy.

Also can I use the same memory that is used in the 1751, 1751-V, 1760,
1760-V, 2610XM, 2611XM, 2620XM, 2621XM, 2650XM and 2651XM group?

PS the specs seem to be

SDRAM, Non-ECC, PC133, 100-pin, 3.3V DC, Time/Speed: 7.5 ns

The reason I ask is that Advanced Enterprise Services seems to need
128MB.


thanks

Well, Cisco specs say that c1721 support max of 96M DRAM so probably you
have seen ios requirements for some other hardware.

Max DRAM option is 64MB. There is onboard DRAM 32MB or 64MB, which is not
removable.
