Compatible Cisco Routers

The Simmtec MEM870-128D is a 128MB DRAM memory card designed for Cisco 871, 876, 877 and 878 series routers. It serves network administrators upgrading branch-office or small-business appliances that require additional system memory. The module matches the Cisco 16-3782-01 part specification for direct replacement.

Pre-Installation Checks

Verify the exact router model number before ordering because this card fits only the four series listed above. Confirm the chassis has a free memory slot and that the current IOS image supports the expanded capacity. Power down the device and follow electrostatic-discharge precautions when handling the module.

Sustained Operation Behaviour

Once installed the DRAM operates continuously at the router's native bus speed without throttling. The memory maintains error-free storage of routing tables, packet buffers and runtime processes during extended uptime. No active cooling is required beyond the chassis airflow designed for the original hardware.
