FAQ
What Cisco router models is this memory module compatible with?
This AddOn MEM-1900-2GB-AO memory module is specifically compatible with Cisco 1941 and 1941W Integrated Services Routers. It serves as a factory-approved compatible replacement for original Cisco memory in these router models, ensuring proper fit and functionality within the router's memory architecture.
What are the key specifications of this DDR2 memory module?
This module features 2GB capacity using DDR2 SDRAM technology operating at 667 MHz with CL5 latency. It utilizes a 240-pin DIMM form factor, operates at 1.80V, and includes ECC (Error Checking and Correction) functionality. The memory conforms to the DDR2-667/PC2-5300 standard for reliable performance in compatible router systems.
What does ECC memory provide for router applications?
ECC (Error Checking and Correction) memory detects and corrects single-bit errors that can occur during data storage and retrieval. In router applications, this protects critical routing tables, configuration data, and network state information from corruption, increasing system reliability and reducing the risk of routing errors or network instability.
How does the 667 MHz speed benefit router performance?
The 667 MHz memory speed reduces data access latency, allowing the router's processor to retrieve routing information and process network packets more quickly. This results in faster routing table lookups, improved packet forwarding performance, and reduced processor idle time waiting for memory access, which is particularly beneficial for routers handling multiple network services simultaneously.
