Description
The HP PM847AV is a 4GB memory kit specifically designed for server environments that utilize DDR2 memory technology. This kit comprises four individual 1GB Registered DIMMs (RDIMMs), each operating at a speed of 400MHz. Registered DIMMs are crucial for server stability as they include a register that buffers command and address signals, reducing electrical load on the memory controller and allowing for higher memory capacities and improved reliability. The memory modules are configured as 1Rx4, indicating they are single-rank modules with a data width of x4. This configuration is often optimized for specific server chipsets and memory controllers to achieve maximum bandwidth and performance. The CAS Latency (CL) is rated at 3, which is a measure of the delay between the memory controller requesting data from the module and the data being available. Lower latency generally translates to faster response times. This 4GB kit is suitable for upgrading the memory in compatible HP ProLiant servers or other systems that support DDR2-400MHz RDIMMs. By increasing the system's RAM, users can expect improved multitasking capabilities, faster application loading times, and better overall system responsiveness, particularly when running memory-intensive applications or virtualized environments.
