Upgrading or Replacing DRAM DIMMs on the RSP4 and RSP8
Depending on your router configuration and the protocols and features your system is running, you
Note
might require more than the 32 MB of default DRAM for your RSP4, and more than the 64 MB of default
DRAM for your RSP8. Upgrade your system DRAM based on your current configuration, this potential
requirement, and the information in
Table 9-2
Quantity

Two 32-MB DIMMs or one

One 128-MB DIMM
Two 128-MB DIMMs
1. The 32-MB DRAM configuration is the default for RSP4s shipped in a Cisco 7507, Cisco 7513, and
Cisco 7576 router.
2. This DRAM product spare option assumes you already have one 32-MB DRAM DIMM installed in an RSP4 and want to
upgrade to 64 MB of DRAM by adding a second 32-MB DRAM DIMM.
3. When using the MEM-RSP4-64M= Product Number to order spare DRAM, note that two 32-MB DIMMs are currently
shipped. As DRAM supplies warrant, these orders may be fulfilled with one 64-MB DIMM in the future.

Quantity
One 64-MB DIMM
One 128-MB DIMM
Two 128-MB DIMMs
1. When using the MEM-RSP8-64M= Product Number to order spare DRAM, note that two 32-MB DIMMs are currently
shipped. As DRAM supplies warrant, these orders may be fulfilled with one 64-MB DIMM in the future.
2. The 64-MB DRAM configuration is the default for RSP8s shipped in a Cisco 7507-MX and Cisco 7513-MX router. Order
this DRAM if you already have 64MB of DRAM in one DIMM socket and want to upgrade to 128 MB of DRAM by adding
64 MB of DRAM in the other DIMM socket.
Caution To prevent system and memory problems when installing DRAM, the RSP4 and RSP8 DRAM DIMMS
must be 3.3V devices. Do not attempt to install higher-voltage devices (such as those designed for the
RSP2) in the RSP4 or RSP8 DIMM sockets.
To prevent system and memory problems, use the same size and type Cisco DIMM in each socket. If you
have a redundant RSP in the system, the memory size and type on the redundant RSP must be the same
as the memory size and type on the primary RSP.
