FAQ
What Cisco router models are compatible with this memory module?
This Axiom 128MB DRAM module is compatible with Cisco 851, 857, 871, 876, 877, and 878 router models. These compatibility specifications ensure the module will function correctly in the memory slots of these specific router platforms without requiring additional configuration or compatibility testing.
What does PC-133 memory standard mean for this module?
PC-133 refers to the memory standard that operates at 133 MHz, providing the data transfer bandwidth appropriate for compatible Cisco router applications. This standard ensures the memory module delivers sufficient performance for routing tables, basic firewall operations, and network services without creating bottlenecks in router functionality.
What is the difference between ECC and Non-ECC memory for routers?
ECC (Error-Correcting Code) memory includes additional circuitry to detect and correct memory errors, while Non-ECC memory does not have this capability. This Axiom module uses Non-ECC architecture because compatible Cisco router models are designed to work with Non-ECC memory, making this the correct choice for these specific router platforms.
What does Unbuffered mean for this DRAM module?
Unbuffered memory modules communicate directly with the memory controller without an intermediate buffer register. This design matches the requirements of compatible Cisco routers, providing simpler signal paths and ensuring compatibility with the router's memory architecture while maintaining reliable data transfer between the memory and controller.
Why is the 168-pin configuration important for this memory module?
The 168-pin configuration ensures proper physical connection and electrical interface with compatible Cisco router memory slots. This specific pin count and layout match the router's memory slot design, providing secure installation and correct signal transmission between the memory module and router motherboard for stable operation.
What warranty coverage does this memory module include?
This Axiom 128MB DRAM module includes a lifetime limited warranty that covers manufacturing defects and ensures long-term reliability. This warranty provides assurance that the memory module will perform as specified throughout its service life in compatible Cisco router installations.
