Product Description
This HP EM151AV memory kit delivers a total of 2GB of memory, split into two 1GB FB-DIMM modules, operating at a DDR2-667MHz frequency. FB-DIMMs are a specialized type of memory module designed for servers and high-end workstations, featuring an Advanced Memory Buffer (AMB) chip that serializes data transfers. This architecture reduces the electrical load on the memory controller, allowing for higher densities and improved signal integrity, which is critical for system stability in demanding environments. The 2Rx8 configuration indicates that each 1GB module is dual-ranked, with each rank having an 8-bit data width. Dual-rank memory can offer performance benefits in certain scenarios by allowing the memory controller to access different ranks concurrently. The CAS Latency (CL) of 5 is a measure of the delay between the memory controller issuing a read command and the data becoming available, providing a good balance for server workloads. As ECC Registered memory, these modules incorporate Error-Correcting Code (ECC) functionality and are registered, meaning they have a buffer chip that reduces the electrical load on the memory controller. This enhances reliability and allows for larger memory capacities to be installed. The EM151AV is intended for use in HP server systems that specifically require DDR2 FB-DIMM memory, ensuring compatibility and optimal performance for critical business operations.
