Dell 8GB 4R RDIMM 1066MHz Memory Module

The Dell A3858988 is an eight-gigabyte memory module that brings new life to a Dell PowerEdge R310 server. Built on DDR3 SDRAM technology, it operates at 1066 MHz and installs in a 240-pin DIMM slot. Because it uses a four-rank registered configuration, the module delivers added signal integrity and stability that standard unbuffered memory cannot match.

Dell qualifies this module specifically for the PowerEdge R310, so you can expand capacity without worrying about firmware conflicts or timing issues. Administrators who run virtualization workloads, database applications, or large file shares on an R310 will see immediate benefits: more memory headroom translates into smoother multitasking, faster response times, and reduced paging to disk.

Installation is straightforward. Power down the server, open the access panel, insert the module into an available DIMM socket, and secure the clips. After power-up, the R310 automatically recognizes the new capacity and adjusts settings to match the 1066 MHz speed.
