Product Description
The HP GZ475AV memory kit provides a total of 2GB of DDR2 RAM, supplied as two 1GB Fully Buffered DIMM (FB-DIMM) modules. These modules operate at a frequency of 667MHz, identified as PC2-5300, and are engineered for server and workstation applications where stability and compatibility are key. The FB-DIMM design incorporates an Advanced Memory Buffer (AMB) chip on each module, which isolates the memory controller from the DRAM chips, thereby improving signal integrity and enabling higher memory capacities and speeds. This kit features a 2Rx8 configuration, indicating that each 1GB module is dual-ranked and uses x8 (8-bit wide) DRAM chips. Dual-ranking allows the memory controller to access different ranks of memory independently, potentially enhancing performance through improved utilization of the memory bus. The x8 DRAM chip width is a common configuration for DDR2 modules. With a CAS Latency (CL) of 5, these modules offer relatively fast response times for DDR2 memory. FB-DIMMs are known to generate significant heat due to the AMB chip, so they are equipped with integrated heat spreaders or heat sinks to manage thermal output and ensure reliable operation within server environments. This HP-branded memory kit is a suitable choice for upgrading or populating memory in compatible server systems.
