Description
This 256MB DDR2 memory module, identified by HP part number DY543AV, is designed for specific HP server and workstation platforms that utilize ECC Unbuffered DIMMs. Operating at a speed of 400MHz, which corresponds to the PC2-3200 standard, it provides adequate bandwidth for entry-level server tasks and older workstation applications. The CAS latency of CL3 is typical for DDR2 memory of this speed, offering a balance between performance and compatibility. As an Unbuffered DIMM (UDIMM), this module does not have an onboard register, meaning command and address signals are sent directly to the memory chips. This makes it suitable for systems with fewer memory slots or lower memory capacity requirements. The inclusion of ECC (Error-Correcting Code) functionality is a key feature, enabling the system to detect and correct single-bit memory errors, thereby enhancing data integrity and system stability, which is crucial in server environments. The HP DY543AV operates at the standard DDR2 voltage of 1.8V. Its compatibility is generally limited to HP systems that specifically list this part number or require DDR2 400MHz ECC UDIMMs. This memory module is a component for maintaining or upgrading specific HP business machines where reliability and error correction are necessary.
