Samsung 256GB DDR4 PC4-21300 2666MHz Memory Kit (8 x 32GB)

The Samsung ASIRAM4 is a 256GB DDR4 PC4-21300 memory kit that equips compatible Dell PowerEdge servers with the headroom required for demanding enterprise workloads. The bundle contains eight DIMMs, each of which provides 32GB of registered DDR4 memory running at 2666 MHz. A 288-pin interface and a CAS latency value of 19 help sustain fast, consistent data transfer during continuous operation.

Designed for Dell PowerEdge models such as the R440, R540, R640, R740, R740XD, T440, T640, and M640, installation is straightforward. Administrators can slide the modules into available slots to boost capacity for virtualization clusters, in-memory databases, real-time analytics, or large file caching without disrupting the existing hardware ecosystem.

Because the kit uses registered DIMMs, it reduces electrical strain on the memory controller, which supports stability when systems run multiple processors and large memory footprints around the clock. The generous 256GB pool allows more virtual machines per host, larger database buffers, and smoother multitasking, helping organizations consolidate workloads and lower total cost of ownership.
