Type of Memory for 4000 series router

I have one Cisco 4500 with 6 Ethernet, and 8 serial port. It has only 32mb dram. (2*16mb). Now I wan to run BGP in this router. So for that I need min of 128mb memory. It has only two memory slots. Is it possible to upgrade that to 128mb. Will it take 2*64 MB, if yes what is the type of memory needed, Please inform me the part number of those memory modules...

Re: Type of Memory for 4000 series router

The 4500 has only 2 slots, which can take only upto 32 MB. (2*16mb). So you cannot subscribe full internet routes on the 4500.

You may be able to get away with 64 MB

We have 4700's with 64 MB DRAM and 16 MB shared that are running BGP & OSPF see below
