Cisco MEM3800-512D enterprise networking (router/Catalyst switch/UCS families) Telecom System Card / Module

The Cisco MEM3800-512D is a 512MB DDR DRAM module, Cisco part number 15-9165-01, built for the Cisco 3800 Series Integrated Services Router, covering the 3825 and 3845 models. It adds to the router’s main system memory, which Cisco IOS uses for routing tables, packet buffering and the security, voice and unified communications feature bundles the 3800 Series was commonly deployed to run; these fuller IOS images typically needed memory beyond the router’s base configuration to run reliably. It uses the DDR memory architecture and DIMM slot layout specific to the 3800 Series and is not interchangeable with the memory used on the smaller 2800 Series or the later 3900 Series ISR G2. The 3825 and 3845 have been end-of-sale for some years but remain in service at a number of branch and regional-office sites. Tech-Star (UK-based, shipped worldwide) stocks Cisco components to support ongoing network maintenance.
