[VoIP] 72 pin EDO memory question

[john jones]

I'm trying to figure out why some 64M 72 pin EDO memory modules don't work in the Cisco MC3810.    Cisco  has always made a  lot of memory  by having internal part numbers with no cross reference numbers.   The 3810 should take 60ns, 16X4 4k EDO, non-parrity modules according to one Cisco document I found.   I thought this meant 16M x 4 bytes (32 bits) and the 4K refers to the refresh rate.  The 64M modules I have all have 8 chips which seems to confirm the no-parity.


Does anyone know what other parameters might exist?  The 3810 uses the Motorola MPC860 processor which can use 8,16,or 32 bits.  I don't know the router uses.

Thanks!
